  HUNT William Holman Notre côte anglaise Né à Londres, 1827 Mort à Londres, 1910 C'est en entrant à la Royal Academy que Hunt rencontra Millais et Rossetti avec qui il élabora, en 1848, les fondements du PRB (Pre-Raphae­ lite Brotherhood) qui déchaîna le scandélle et les polémiques. Les préraphaélites avaient eu l'impudence de condamner la valorisation exces­ sive (à leurs yeux) des œuvres de Raphaël en déclarant qu'il fallait se pencher sur...

Il réussit la premiè­ re transplantation tissulaire de l'éperon (ou ergot) de la patte d'un coq sur l'os frontal de l'animal. Il avait un énorme pouvoir de concentration. Un contemporain le décrivit de la façon suivante: ' II restait debout durant des heures, aussi immobile qu'une statue, à l'exception de ses mains qui tenaient des pinces pour séparer les fibres d'un...

• Lion - biology.

  Lions usually hunt at night, alone, or in groups. Their preferred prey are large hoofed mammals, such as zebras and wildebeests, but they will go after small hares aswell as huge giraffes. Typically, a lion hunting alone will slowly and silently stalk its prospective victim, trying not to be seen, until it is about 30 m (about 98 ft) away.Then with a burst of speed, the lion will run toward the prey, grab it, and throw it to the ground. The lion kills the prey by biting the back of the animal’s...

• Tiger - biology.

  have a simple digestive system designed to process meat so that the nutrients can be readily absorbed into the bloodstream. With the exception of white tigers, which have blue eyes, all tigers have yellow eyes. Tigers mainly use vision to find prey. Although tigers see about as well as humansduring the day, their large eye openings gather more light than do human eyes, making tiger night vision far superior to that of humans. In addition, a special structurein the tiger’s eye, called the tapetu...

• Dog Family - biology.

  muzzles, long and bushy tails, and large ears. Many foxes hunt by stalking prey and then leaping on it with a distinctive, stiff-legged pounce. Once thought to besolitary animals, foxes are now known to live in groups of up to six individuals. The remaining canids are each highly distinctive. Raccoon dogs and bush dogs are the least doglike canids in appearance. Raccoon dogs, found in eastern Asia, havestubby legs, a stout body, short ears, shaggy fur, and a black face mask that resembles a racc...

• Cat Family - biology.

  cats have coats that are mainly brown, yellow, or gray, often with white underbellies. The cubs of many species of cats have spotted coats, which helps hide them ingrass and underbrush from predators. Adult cats that have mainly spotted patterns in their fur include cheetahs, leopards, clouded leopards, jaguars, ocelots, margays, Geoffroy’s cat, and servals. Singlecolor coats are found in lions, pumas, and jaguarundis. Some individuals among leopards and jaguars, and more rarely in other species...

• Whales.

  whales travel to cool waters near the Arctic or Antarctica every summer. They feed on krill , small animals that look like shrimp. In the winter, baleen whales head for warmer waters near the equator tobreed. Other whales do not migrate. Narwhals, for instance, live year-round in the cool waters of the Arctic andNorth Atlantic oceans. HAVING BABY WHALES After male and female whales mate, it takes from 10 to 16 months for a baby whale to form. The lengthof time depends on the whale species. A wh...

• Stone Age.

  limestone, quartzite, and indurated shale. Ground stone tools could be made on a wider range of raw material types, including coarser grained rock such as granite. Flaking produces several different types of stone artifacts, which archaeologists look for at prehistoric sites. The parent pieces of rock from which chips have beendetached are called cores, and the chips that have been removed from cores are called flakes. A flake that has had yet smaller flakes removed from one or more edgesin orde...

• Reptiles.

  to find mates. A male turtle may stroke a female’s face with his front limbs. Most female reptiles make nests and lay eggs. A few lizards and snakes give birth to live young. All baby reptiles can live on their own as soon as they hatch. But most baby reptiles do not live morethan a few months. Birds, snakes, and mammals eat them. Sharks hunt baby sea turtles. Reptiles can live a long time if they don’t get eaten. Some tortoises may live up to 150 years. Alligatorscan live more than 70 years. Sm...

• Jaguar (animal) - biology.

  scientists have speculated that the jaguar’s robust canine teeth and enormously powerful bite developed specifically to pierce the armor of these reptiles. After killing a large animal, a jaguar will usually drag the carcass into dense cover before beginning to eat. If the kill is made in an open area, jaguars often drag theirprey for considerable distances. On one occasion, a jaguar killed a cow on the edge of a river and swam 790 m (2,600 ft) across the river carrying the cow. Unlike the other...

• Eagle - biology.

  States, is a member of this group found only in North America. It is named for its snow-white head. However, the name bald does not refer to a lack of feathers but comes instead from an outdated word meaning marked with white, as in piebald. The adult bald eagle is blackish brown, with a white head and tail. Its bill, legs, and feet are bright yellow. The bill, which is longer and heavier than the gray bill of golden eagles, is useful for piercing the skin of fish. Bald eagles vary in size....

• Alligators and Crocodiles.

  During cold winters, alligators bury themselves in mud. There they can hibernate until spring. WHERE CROCODILES LIVE Four species of crocodiles live in the Americas. These crocodiles are found in southern Florida, Cuba andother Caribbean islands, southern Mexico, Central America, and northern South America. The Indo-Pacific crocodile lives along the seacoasts of India, southern China, Malaysia, and Australia.The swamp crocodile is found in the lakes and rivers of India. The Nile crocodile lives...

• Cheetah - biology.

  animals such as zebras. Unlike most cats, cheetahs hunt during the day, when lions and hyenas that compete with them for prey are less likely to be active. Still,scientists in Tanzania have observed that cheetahs lose 10 to 13 percent of their kills to lions and hyenas. Alerted by the panic of a gazelle herd or by the circling ofvultures, lions and hyenas close in and easily drive the more timid cheetah away from a fresh kill. A cheetah usually stalks prey to within about 10 m (about 33 ft) and...

Richvolcanic soils are found throughout much of the region. A2 People and Languages Mesoamerica was a great melting pot, home to many peoples and interrelated cultures. In...

• First Americans.

  bones and artifacts helped 19th-century archaeologists establish the age of ancient human encampments in Europe. Yet, search as they might, American archaeologists found no comparable evidence of a Pleistocene-era human presence. But several sites revealed stone artifacts thatsome scholars believed looked similar to the ancient stone tools found in Europe. On the basis of this similarity, these experts claimed the American artifacts must be asold. By the 1890s, however, other scholars had challe...

• Wolf - biology.

  VIII RED WOLF The red wolf is smaller than the gray wolf. An adult red wolf stands about 65 cm (about 2 ft) high at the shoulder, measures 100 to 130 cm (3 to 4 ft) in lengthexcluding the tail, and weighs 20 to 36 kg (45 to 80 lb). It has long legs and ears and its head is not as wide as that of the gray wolf. The coat of red wolves varies incolor from light tan to black with reddish head, ears, and legs. Scientists have debated whether the red wolf is a subspecies of the gray wolf, a separate...

• Nunavut - Canadian History.

  The Arctic Lands is a complex geological area that is centered on the Arctic Ocean. It includes coastal plains, plateaus, and mountains. Coastal plains and plateaus arefound in the western Northwest Territories section of the Arctic Lands, such as on Victoria Island, which is mostly a large, flat plateau. In striking contrast to theserelatively gentle landscapes, the eastern Nunavut section of the Arctic Lands is dominated by a jagged chain of ice-covered mountains. The mountains on EllesmereIsl...

Diese Formationen stellen zusammen mit der Antarktis das Herzstück des alten Kontinents dar, der sich vor weniger als 200 MillionenJahren im Jura von Gondwana abspaltete und in östliche und nördliche Richtung fortzudriften begann ( siehe Plattentektonik, Kontinent). Vor ungefähr 100 Millionen Jahren entstand Australien als eigenständiger Kontinent, nachdem sich die Antarktis abgetrennt und in südliche Richtung bewegt hatte. Auch heute noch entfernt sich derau...

• Zebras.

  All zebras like physical contact. They groom each other by nibbling on each other’s fur. They flick theirtails to keep flies away from each other’s faces. THREATS TO ZEBRAS The main natural enemies of zebras are lions, hyenas, and other wild animals. However, people are agreater threat to zebras. People hunt zebras. They hunted a kind of zebra called the quagga until theanimal died out. Today, Grévy’s zebra and the mountain zebra are endangered. People still hunt them for meat and hides.People t...

• Eagles.

  THREATS TO EAGLES Eagles do not like to live near people. Because they are such big birds, they need lots of room to hunt.People have moved into wilderness areas where eagles lived and built farms and cities. People have alsohunted eagles. Chemicals used in farming have reduced the number of eagles. Many kinds of eagles,including the American bald eagle, became endangered during the 20th century. Some governments have passed laws to protect eagles. Conservation groups also worked to help savethe...

• Penguin - biology.

  B Parents and Offspring Once female penguins lay their eggs, both the parents incubate the eggs. The incubation period varies according to species, ranging from 33 days for the little penguinto about 63 days for the emperor penguin. In most medium-sized penguins incubation takes 35 to 38 days. The incubation routine is highly variable among penguinspecies, although in general both sexes participate in incubation and feeding of young. Male and female Adélie penguins take turns incubating their e...

• African Literature I INTRODUCTION African Literature, oral and written literature produced on the African continent.

  that few scholars of African culture know any African languages, and few Africans know an African language other than their own. The best-known literatures in Africanlanguages include those in Yoruba and Hausa in West Africa; Sotho, Xhosa, and Zulu in southern Africa; and Amharic, Somali, and Swahili in East Africa. In West Africa, Yoruba writing emerged after Bishop Ajayi Crowther, a former slave, developed a script for the language and in 1900 published the first Yorubatranslation of the Bible...

• Mammal - biology.

  On land, mammals live in many different habitats, and at a wide range of altitudes. Many mammals dig burrows as refuges or as places to raise their young, but somehave developed a largely subterranean lifestyle, feeding on small animals or plant roots beneath the soil's surface. These animals, including moles and mole-rats, digthrough the ground either with spadelike front paws or with their teeth, and they detect danger by being highly sensitive to vibrations transmitted through the soil.Most m...
