Colour, size, and method of living, being therefore insufficient, there remains only those essential characters which may be derived from their figure. Now, all that travellers have said of the sea-bear is simply, that his head, body, and hair, are longer than in our bears, and his head much harder. If these differences be real and striking, they would suffice to constitute a different species: but I am doubtful whether Martin examined them with accuracy, and whether the others, who copied from him, have not exaggerated. "These white bears (says he) are shaped quite otherwise than those in our country; they have a long head like that of a dog, and the neck is also long; they bark almost like dogs that are hoarse; they are not so clumsy, and more nimble than our bears; they are nearly of the same size; their hair is long, and softer than wool. It is said, that common bears have a very tender head, but it is quite contrary with the white bear, for though we gave one several blows over the head, he was not in the least stunned, although they were sufficient to have knocked down an ox.[AB]" We may remark from this description, first, that the author does not speak of these bears as being larger than ours, and that, consequently we ought to suspect the testimony of those who have affirmed, that the sea-bears were thirteen feet long. Secondly, that the hair being as soft as wool does not constitute a specific character, since an animal's going frequently in the water is a sufficient cause for the hair becoming softer, and even more bushy, as is seen by the land and water beaver: those that live upon land, rather than in the water, having a rougher and thinner hair; and what makes me suspect that the other differences are not real, nor even so apparent as Martin speaks of, is that Dithmar Blefklein, in his description of Iceland, speaks of these white bears, and asserts having seen one of them killed in Greenland, which reared itself on his hind feet like other bears; but in this recital, he does not say a word which indicates that the white Greenland bear is not entirely like ours. Besides, when these animals find prey upon land, they do not seek for food in the sea: they devour rein-deer, and any other beast they can seize; they even attack men, and dig up dead bodies. But when almost famished, as they often find themselves in those desart and barren lands, they are obliged to frequent the water, in quest of seals, young walruses, and small whales. They get upon the islands of ice, where they wait for their prey; and as long as they find abundance of subsistence, they never quit their post; so that when the ice begins to float in spring, they suffer themselves to be carried away with it, and as they cannot regain the land, nor even quit the ice on which they are embarked for a long time, they frequently perish in the open sea. Those which arrive on the coasts of Norway or Iceland with these floats of ice, are so nearly famished,
