Body characteristics

Trunk

The proboscis, or trunk, is a fusion of the nose and upper lip, elongated and specialized to become the elephant's most important and versatile appendage. African elephants are equipped with two fingerlike projections at the tip of their trunk, while Asians have only one. According to biologists, the elephant's trunk is said to have over forty thousand individual muscles in it[1], making it sensitive enough to pick up a single blade of grass, yet strong enough to rip the branches off a tree. Some sources indicate that the correct number of muscles in an elephant's trunk is nearer to one hundred thousand. [2]

Most herbivores (plant eaters, like the elephant) are adapted with teeth for cutting and tearing off plant materials. However, except for the very young or infirm, elephants always use their trunks to tear up their food and then place it in their mouth. They will graze on grass or reach up into trees to grasp leaves, fruit, or entire branches. If the desired food item is too high up, the elephant will wrap its trunk around the tree or branch and shake its food loose or sometimes simply knock the tree down altogether. The trunk is also used for drinking. Elephants suck water up into the trunk (up to fifteen quarts [14.2 litres] at a time) and then blow it into their mouth. Elephants also inhale water to spray on their body during bathing. On top of this watery coating, the animal will then spray dirt and mud, which act as a protective sunscreen.

This appendage also plays a key role in many social interactions. Familiar elephants will greet each other by entwining their trunks, much like a handshake. They also use them while play-wrestling, caressing during courtship, and for dominance displays - a raised trunk can be a warning or threat, while a lowered trunk can be a sign of submission. Elephants can defend themselves very well by flailing their trunk at unwanted intruders or by grasping and flinging them.

An elephant also relies on its trunk for its highly developed sense of smell. Raising the trunk up in the air and swivelling it from side to side, like a periscope, it can determine the location of friends, enemies, and food sources.

Tusks

The tusks of an elephant are its second upper incisors. Tusks grow continuously; an adult male's tusks will grow about seven inches a year. Tusks are used to dig for water, salt, and roots; to debark trees, to eat the bark; to dig into baobab trees to get at the pulp inside; and to move trees and branches when clearing a path. In addition, they are used for marking trees to establish territory and occasionally as weapons.

Like humans who are typically right- or left-handed, elephants are usually right- or left-tusked. The dominant tusk, called the master tusk, is generally shorter and more rounded at the tip from wear. Both male and female African elephants have large tusks that can reach over 10 ft (3 m) in length and weigh over 200 lb (90 kg). In the Asian species, only the males have large tusks. Female Asians have tusks which are very small or absent altogether. Asian males can have tusks as long as the much larger Africans, but they are usually much slimmer and lighter; the heaviest recorded is 86 lb (39 kg). The tusk of both species is mostly made of calcium phosphate in the form of apatite. As a piece of living tissue, it is relatively soft (compared with other minerals such as rock), and the tusk, also known as ivory, is strongly favoured by artisans for its carvability. The desire for elephant ivory has been one of the major factors in the dramatic decline of the world's elephant population.

Some extinct relatives of elephants had tusks in their lower jaws also (e.g. Tetrabelodon), or instead (e.g. Dinotherium).

Teeth

Elephants' teeth are very different from those of most other mammals. Over their lives they usually have 28 teeth. These are:

Unlike most mammals, which grow baby teeth and then replace them with a permanent set of adult teeth, elephants have cycles of tooth rotation throughout their entire life. After one year the tusks are permanent, but the other teeth are replaced five times in an elephant's life. The teeth do not emerge from the jaws vertically like with human teeth. Instead, they have a horizontal progression, like a conveyor belt. New teeth grow in at the back of the mouth, pushing older teeth toward the front, where they wear down with use and the remains fall out. When an elephant becomes very old, the last set of teeth is worn to stumps, and it must rely on softer foods to chew. Very elderly elephants often spend their last years exclusively in marshy areas where they can feed on soft wet grasses. Eventually, when the last teeth fall out, the elephant will be unable to eat and will die of starvation. Were it not for tooth wearout, their metabolism would allow them to live much longer. Rupert Sheldrake has proposed this as an explanation for the elephant graveyards. However, as more habitat is destroyed, the elephants' living space becomes smaller and smaller; the elderly no longer have the opportunity to roam in search of more appropriate food and will, consequently, die of starvation at an earlier age.

Tusks in the lower jaw are also second incisors. These grew out large in Dinotherium and some mastodons, but in modern elephants they disappear early without erupting.

Skin

Elephants are called pachyderms, which means thick-skinned animals. An elephant's skin is extremely tough around most parts of its body and measures about 2.5 cm (1 in) thick. However, the skin around the mouth and inside of the ear is paper thin. Normally, the skin of an Asian is covered with more hair than its African counterpart. This is most noticeable in the young. Asian calves are usually covered with a thick coat of brownish red fuzz. As they get older, this hair darkens and becomes more sparse, but it will always remain on their heads and tails.

The species of elephants are typically grayish in colour, but the Africans very often appear brown or reddish from wallowing in mud holes of coloured soil. Wallowing is actually a very important behaviour in elephant society. Not only is it important for socialization, but the mud acts as a sunscreen, protecting their skin from harsh ultraviolet radiation. Though tough, an elephant's skin is very sensitive. Without regular mud baths to protect it from burning, as well as from insect bites and moisture loss, an elephant's skin would suffer serious damage. After bathing, the elephant will usually use its trunk to blow dirt on its body to help dry and bake on its new protective coat. As elephants are limited to smaller and smaller areas, there is less water available, and local herds will often come too close over the right to use these limited resources.

Wallowing also aids the skin in regulating body temperatures. Elephants spend every day fighting an uphill battle to stay cool. They have a very difficult time releasing heat through the skin because, in proportion to their body size, they have very little of it. The ratio of an elephant's mass to the surface area of its skin is many times that of a human. Elephants have even been observed lifting up their legs to expose the soles of their feet, presumably in an effort to expose more skin to the air. Since wild elephants live in very hot climates, they must have other means of getting rid of excess heat.

Legs and Feet

An elephant's legs are great straight pillars, as they must be to support its bulk. The elephant needs less muscular power to stand because of its straight legs. For this reason an elephant can stand for very long periods of time without tiring. In fact, African elephants rarely lie down unless they are sick or wounded. However, Indian elephants lie down frequently. Elephants are the only mammals to have four knees, most others either have two knees and two elbows, though the knees are often found in the front legs, or they have four elbows, like cats or dogs.[citation needed]

The feet of an elephant are nearly round. African elephants have three nails on each hind foot, and four on each front foot. Indian elephants have four nails on each hind foot and five on each front foot. Beneath the bones of the foot is a tough, gelatine-like material that acts as a cushion or shock absorber. Under the elephant's weight the foot swells, but it gets smaller when the weight is removed. An elephant can sink deep into mud, but can pull its legs out readily because its feet become smaller when they are lifted.

An elephant is a good swimmer and climber, but it can neither trot, run, jump, nor gallop. It has only one gait, a sort of gliding shuffle, which it can step up to the speed of a human sprinter. There are few animals that can travel farther in a day than the elephant.

Ears

The large flapping ears of an elephant are also very important for temperature regulation. Elephant ears are made of a very thin layer of skin stretched over cartilage and a rich network of blood vessels. On hot days, elephants will flap their ears constantly, creating a slight breeze. This breeze cools the surface blood vessels, and then the cooler blood gets circulated to the rest of the animal's body. The hot blood entering the ears can be cooled as much as ten degrees Fahrenheit before returning to the body. Differences in the ear sizes of African and Asian elephants can be explained, in part, by their geographical distribution. Africans originated and stayed near the equator, where it is warmer. Therefore, they have bigger ears. Asians live farther north, in slightly cooler climates, and thus have smaller ears.

The ears are also used in certain displays of aggression and during the males' mating period. If an elephant wants to intimidate a predator or rival, it will spread its ears out wide to make itself look more massive and imposing. During the breeding season, males give off an odor from a gland located behind their eyes. Joyce Poole, a well-known elephant researcher, has theorized that the males will fan their ears in an effort to help propel this "elephant cologne" great distances.

Walking at a normal pace an elephant covers about 2 to 4 miles an hour (3 to 6 km/h) but they can reach 24 miles an hour (40 km/h) at full speed.

 

Evolution

Although the fossil evidence is uncertain, some scientists believe there is genetic evidence that the elephant family shares distant ancestry with the Sirenians (sea cows) and the hyraxes. In the distant past, members of the hyrax family grew to large sizes, and it seems likely that the common ancestor of all three modern families was some kind of amphibious hyracoid. One theory suggests that these animals spent most of their time under water, using their trunks like snorkels for breathing. Modern elephants have retained this ability and are known to swim in that manner for up to 6 hours and 50 km.

In the past, there was a much wider variety of elephant genera, including the mammoths, stegodons and deinotheria. There was also a much wider variety of species.[14][15]

 

Diet

Elephants are herbivores, spending 16 hours a day collecting plant food. Their diet is at least 50% grasses, supplemented with leaves, bamboo, twigs, bark, roots, and small amounts of fruits, seeds and flowers. Because elephants only digest 40% of what they eat, they have to make up for their digestive system's lack of efficiency in volume. An adult elephant can consume 300–600 lb (140–270 kg) of food a day. 60% of that food leaves the elephant's body undigested.

 

Social behavior

Elephants live in a very structured social order. The social lives of male and female elephants are very different. The females spend their entire lives in tightly knit family groups made up of mothers, daughters, sisters, and aunts. These groups are led by the eldest female, or matriarch. Adult males, on the other hand, live mostly solitary lives.

The social circle of the female elephant does not end with the small family unit. In addition to encountering the local males that live on the fringes of one or more groups, the female's life also involves interaction with other families, clans, and subpopulations. Most immediate family groups range from five to fifteen adults, as well as a number of immature males and females. When a group gets too big, a few of the elder daughters will break off and form their own small group. They remain very aware of which local herds are relatives and which are not.

The life of the adult male is very different. As he gets older, he begins to spend more time at the edge of the herd, gradually going off on his own for hours or days at a time. Eventually, days become weeks, and somewhere around the age of fourteen, the mature male, or bull, sets out from his natal group for good. While males do live primarily solitary lives, they will occasionally form loose associations with other males. These groups are called bachelor herds. The males spend much more time than the females fighting for dominance with each other. Only the most dominant males will be permitted to breed with cycling females. The less dominant ones must wait their turn. It is usually the older bulls, forty to fifty years old, that do most of the breeding. The dominance battles between males can look very fierce, but typically they inflict very little injury. Most of the bouts are in the form of aggressive displays and bluffs. Ordinarily, the smaller, younger, and less confident animal will back off before any real damage can be done. However, during the breeding season, the battles can get extremely aggressive, and the occasional elephant is injured. During this season, known as musth, a bull will fight with almost any other male it encounters, and it will spend most of its time hovering around the female herds, trying to find a receptive mate.

 

Self-awareness

From a study reported in Proceedings of the National Academy of Sciences, an Asian elephant housed at the Bronx Zoo in New York, repeatedly touched a white cross painted above its eye, when it saw this mark reflected in a large mirror. Another mark made on the forehead in colourless paint, was ignored, showing that it was not the smell or feeling which caused the interest. Elephants are among the very small number of species such as the great apes and Bottlenose Dolphins capable of self-recognition.[16][17]

 

Homosexuality

African, as well as Asiatic males will engage in same-sex bonding and mounting. Such encounters are often associated with affectionate interactions such as kissing, trunk intertwining or placing trunks in each other's mouth. The encounters are analogous to heterosexual bouts, one male often extending his trunk along the other's back and pushing forward with his tusks to signify his intention to mount. Unlike heterosexual relations, which are always of a fleeting nature, often males will form a "companionship" consisting of an older individual and one or two younger attendant males. Same sex relations are common and frequent in both sexes, with Asiatic elephants in captivity devoting roughly 45% of sexual encounters to same-sex activity.[18]

 

Communication

It has been discovered that elephants can communicate over long distances by producing and receiving low frequency infrasound, a sub-sonic rumbling which can travel through the ground farther than sound travels in the air. This can be felt by the sensitive skin of an elephant's feet and trunk, which pick up the resonant vibrations in much the same way as the flat skin on the head of a drum. To listen attentively, the whole herd will lift one foreleg from the ground, and face the source of the sound, or often lay their trunks on the ground - the lifting presumably increases the ground contact and sensitivity of the remaining legs. This ability is thought to also aid their navigation by utilizing external sources of infrasound. Discovery of this new aspect of elephant social communication and perception is due to breakthroughs in audio technology, which can pick up frequencies outside the range of the human ear. Pioneering research in elephant infrasound communication was done by Katy Payne of the Elephant Listening Project,[19] and is detailed in her book Silent Thunder. Though this research is still in its infancy, it is helping to solve many prior mysteries such as how elephants can find distant potential mates, and how social groups are able to coordinate their movements over an extensive territory range.

 

Reproduction, calves, and calf rearing

Reproduction

Females (cows) reach sexual maturity at around 9-12 years of age and become pregnant for the first time, on average, around age 13. They can reproduce until ages 55-60. Females give birth at intervals of about every 5 years. An elephant's gestation (pregnancy) period lasts about 22 months (630-660 days), the longest gestation period of any mammal, after which one calf typically is born. Twins are rare. Labor ranges in length from 5 minutes to 60 hours. The average length of labor is 11 hours. At birth, calves weigh around 90–115 kg (200–250 lb), and they gain 1 kg (2–2.5 lb) a day. In the wild, the mother is accompanied by other adult females (aunts) that protect the young, and baby elephants are raised and nurtured by the whole family group, practically from the moment they are born.

Motherhood and calf rearing

Elephant calves

Elephant social life, in many ways, revolves around breeding and raising of the calves. A female will usually be ready to breed around the age of thirteen, at which time she will seek out the most attractive male to mate with. Females are generally attracted to bigger, stronger, and, most importantly, older males. Such a reproductive strategy tends to increase their offsprings' chances of survival.

After a twenty-two-month pregnancy, the mother will give birth to a calf that will weigh about 250 lb and stand over 2½ feet tall. Elephants have a very long childhood. They are born with fewer survival instincts than many other animals. Instead, they must rely on their elders to teach them the things they need to know. The ability to pass on information and knowledge to their young has always been a major asset in the elephant's struggle to survive. Today, however, the pressures humans have put on the wild elephant populations, from poaching to habitat destruction, mean that the elderly often die at a younger age, leaving fewer teachers for the young.

All members of the tightly knit female group participate in the care and protection of the young. Since everyone in the herd is related, there is never a shortage of baby-sitters. In fact, a new calf is usually the center of attention for all herd members. All the adults and most of the other young will gather around the newborn, touching and caressing it with their trunks. The baby is born nearly blind and at first relies, almost completely, on its trunk to discover the world around it.

Allomothers

After the initial excitement dies down, the mother will usually select several full-time baby-sitters, or "allomothers", from her group. According to Cynthia Moss, a well-known researcher, these allomothers will help in all aspects of raising the calf.[citation needed] They walk with the young as the herd travels, helping the calves along if they fall or get stuck in the mud. The more allomothers a baby has, the more free time its mother has to feed herself. Providing a calf with nutritious milk means the mother has to eat more nutritious food herself. So, the more allomothers, the better the calf's chances of survival.

 

Effect on the environment

Elephants' foraging activities help to maintain the areas in which they live:

Threat of extinction

Hunting

The threat to the African elephant presented by the ivory trade is unique to the species. Larger, long-lived, slow-breeding animals, like the elephant, are more susceptible to overhunting than other animals. They cannot hide, and it takes many years for an elephant to grow and reproduce. An elephant needs an average of 300 lb (140 kg) of vegetation a day to survive. As large predators are hunted, the local small grazer populations (the elephant's food competitors) find themselves on the rise. The increased number of herbivores ravage the local trees, shrubs, and grasses. Elephants themselves have few natural predators besides man and, occasionally, lions.

 

Dehabitation

Another threat to elephant's survival in general is the ongoing cultivation of their habitats with increasing risk of conflicts of interest with human cohabitants. These conflicts kill 150 elephants and up to 100 people per year in Sri Lanka.[20] Lacking the massive tusks of its African cousins, the Asian elephant's demise can be attributed mostly to loss of its habitat.As larger patches of forest disappear, the ecosystem is affected in profound ways. The trees are responsible for anchoring soil and absorbing water runoff. Floods and massive erosion are common results of deforestation. Elephants need massive tracts of land because, much like the slash-and-burn farmers, they are used to crashing through the forest, tearing down trees and shrubs for food and then cycling back later on, when the area has regrown. As forests are reduced to small pockets, elephants become part of the problem, quickly destroying all the vegetation in an area, eliminating all their resources.

 

Controversy

Despite all the fears of extinction, some scholars claim that the elephant population of Africa as a whole has actually increased over the past ten years, most notably in Botswana, which currently is experiencing elephant overpopulation. [3]

 

National parks

Africa's first official reserve eventually became one of the world's most famous and successful national parks. Kruger National Park in South Africa first became a reserve against great opposition in 1898 (then Sabi Reserve). It was deproclaimed and reproclaimed several times before it was renamed and granted national park status in 1926. It was to be the first of many.

Of course, there were many problems in establishing these reserves. For example, elephants range through a wide tract of land with little regard for national borders. however, when most parks were created, the boundaries were drawn at the human-made borders of individual countries. Once a fence was erected, many animals found themselves cut off from their winter feeding grounds or spring breeding areas. Some animals died as a result, while some, like the elephants, just trampled through the fences. This did little to belie their image as a crop-raiding pest. The more often an elephant wandered off its reserve, the more trouble it got into, and the more chance it had of being shot by an angry farmer. When confined to small territories, elephants can inflict an enormous amount of damage to the local landscapes. Today there are still many problems associated with these parks and reserves, but there is now little question as to whether or not they are necessary. As scientists learn more about nature and the environment, it becomes very clear that these parks may be the elephant's last hope against the rapidly changing world around them.

Additionally, Kruger National Park has suffered from elephant overcrowding, at the expense of other species of wildlife within the reserve. South Africa slaughtered 14,562 elephants in the reserve between 1967 and 1994; it stopped in 1995, mostly due to international and local pressure. Without action, it is predicted that the elephant population in Kruger National Park will triple to 34,000 by 2020.[21]

 

Humanity and elephants

Harvest from the wild

The harvest of elephants, both legal and illegal, has had some unexpected consequences on elephant anatomy as well. African ivory hunters, by killing only tusked elephants, have given a much larger chance of mating to elephants with small tusks or no tusks at all. The propagation of the absent-tusk gene has resulted in the birth of large numbers of tuskless elephants, now approaching 30% in some populations (compare with a rate of about 1% in 1930). Tusklessness, once a very rare genetic abnormality, has become a widespread hereditary trait.

It is possible, if unlikely, that continued selection pressure could bring about a complete absence of tusks in African elephants, a development normally requiring thousands of years of evolution. The effect of tuskless elephants on the environment, and on the elephants themselves, could be dramatic. Elephants use their tusks to root around in the ground for necessary minerals, tear apart vegetation, and spar with one another for mating rights. Without tusks, elephant behavior could change dramatically.[22]

 

Domestication and use

Elephants have been working animals used in various capacities by humans. Seals found in the Indus Valley suggest that the elephant was first domesticated in ancient India. However, elephants have never been truly domesticated: the male elephant in his periodic condition of musth is dangerous and difficult to control. Therefore elephants used by humans have typically been female, war elephants being an exception, however: as female elephants in battle will run from a male, only males could be used in war. It is generally more economical to capture wild young elephants and tame them than breeding them in captivity (see also elephant "crushing").

War elephants were used by armies in the Indian sub-continent, and later by the Persian empire. This use was adopted by Hellenistic armies after Alexander the Great experienced their worth against king Porus, notably in the Ptolemaic and Seleucid diadoch empires. The Carthaginian general Hannibal took elephants across the Alps when he was fighting the Romans, but brought too few elephants to be of much military use, although his horse cavalry was quite successful; he probably used a now-extinct third African (sub)species, the North African (Forest) elephant, smaller than its two southern cousins, and presumably easier to domesticate. A large elephant in full charge could cause tremendous damage to infantry, and cavalry horses would be afraid of them (see Battle of Hydaspes).

Throughout Siam, India, and most of South Asia elephants were used in the military for heavy labor, especially for uprooting trees and moving logs, and were also commonly used as executioners to crush the condemned underfoot.

Elephants have also been used as mounts for safari-type hunting, especially Indian shikar (mainly on tigers), and as ceremonial mounts for royal and religious occasions, whilst Asian elephants have been used for transport and entertainment, and are common to circuses around the world.

African elephants have long been reputed to not be domesticable, but some entrepreneurs have succeeded by bringing Asian mahouts from Sri Lanka to Africa. In Botswana, Uttum Corea has been working with African elephants and has several young tame elephants near Gaborone. African elephants are more temperamental than Asian elephants, but are easier to train. Because of their more sensitive temperaments, they require different training methods than Asian elephants and must be trained from infancy hence Corea worked with orphaned elephants. African elephants are now being used for (photo) safaris. Corea's elephants are also used to entertain tourists and haul logs.

Elephants are also commonly exhibited in zoos and wild animal parks, the former of which has caused controversy. Animal rights advocates allege that elephants in zoos "suffer a life of chronic physical ailments, social deprivation, emotional starvation, and premature death". [4] However, zoos argue that standards for treatment of elephants are extremely high and that minimum requirements for such things as minimum space requirements, enclosure design, nutrition, reproduction, enrichment and veterinary care are set to ensure the wellbeing of elephants in captivity.

 

Elephant traps

A method of confining elephants practiced in the Indian Subcontinent is far less physical and brutal, and more psychological, than earlier means. It is called the "elephant trap". The following is taken from a newsletter:

From when an elephant is a baby they tie him for certain periods with a rope to a tree. The young elephant tries his hardest to escape, he pulls and wriggles and jumps and crawls yet the rope just tightens and to the tree it remains tied. Learning that, the elephant doesn’t try to escape and accepts his confinement. A couple of years pass and the elephant is now an adult weighing several tons. Yet the trainer continues to tie the elephant to the tree with the same rope he’s always used, for the simple reason that the elephant has the concept in his mind that the rope is stronger than him. Abiding to this conditioning the elephant is trapped for life. To break free all the elephant has to do is erase that limiting thought for in fact he is free to go.

Elephant rage

Musth

Adult male elephants naturally enter the periodic state called musth (Hindi for madness), sometimes spelt "must" in English. It is characterised by very excited and/or aggressive behavior and a thick, tar-like liquid secretion that discharges through the temporal ducts from the temporal glands on the sides of the head. Musth is linked to sexual arousal or establishing dominance but this relationship is far from clear. A musth elephant, wild or domesticated, is extremely dangerous to humans. Domesticated elephants in India are traditionally tied to a tree and denied food and water for several days, after which the musth passes. In zoos, musth is often the cause of fatal accidents to elephant keepers. Zoos keeping adult male elephants need extremely secure enclosures, which greatly complicates the attempts to breed elephants in zoos.

Musth is accompanied by a significant rise in reproductive hormones. Testosterone levels in an elephant in musth can be as much as 60 times greater than in the same elephant at other times. However, whether this hormonal surge is the sole cause of musth, or merely a contributing factor is unknown: scientific investigation of musth is greatly hindered by the fact that even the most otherwise placid of elephants may actively try to kill any and all humans. Similarly, the tar-like secretion remains largely uncharacterised, due to the extreme difficulties of collecting a sample for analysis.

Although it has often been speculated that musth is linked to rut, this is unlikely, because the female elephant's estrus cycle is not seasonally-linked. Furthermore, bulls in musth have often been known to attack female elephants, regardless of whether or not the females are in heat.

The Hindi word "musth" is from the Urdu mast, which in turn is from a Persian root meaning 'intoxicated'.

The Channel 5 British television program "The Dark Side of Elephants" (20 March 2006) stated that during musth:

Other causes

At least a few elephants have been suspected to be drunk during their attacks. In December 1998, a herd of elephants overran a village in India. Although locals reported that nearby elephants had recently been observed drinking beer which rendered them "unpredictable", officials considered it the least likely explanation for the attack.[23] An attack on another Indian village occurred in October 1999, and again locals believed the reason was drunkenness, but the theory was not widely accepted.[24] Purportedly drunk elephants raided yet another Indian village again on December 2002, killing six people, which led to killing of about 200 elephants by locals.[25]

Charles Siebert reports in his New York Times article An Elephant Crackup? that:

Since the early 1990’s, for example, young male elephants in Pilanesberg National Park and the Hluhluwe-Umfolozi Game Reserve in South Africa have been raping and killing rhinoceroses; this abnormal behavior, according to a 2001 study in the journal Pachyderm, has been reported in ‘‘a number of reserves’’ in the region.[26]

 

 

Rogue elephant

Rogue elephant is a term for a lone, violently aggressive wild elephant, separated from the rest of the herd. It is a calque of the Sinhala term hora aliya. Its introduction to English has been attributed by the Oxford English Dictionary to Sir James Emerson Tennant, but this usage may have been pre-dated by William Sirr.
