The head and the body generally is covered with very long silky hairs of a dark colour; some of which are seventeen inches long; on the middle of the back (which is broad and flat), the hair is lighter and not so long. Beneath the long hairs, in all parts, there is a thick coat of cinereous wool of exquisite fineness. M. Jeramie brought some to France, of which stockings were made more beautiful than silk. The tail is only three inches long, and completely covered with very long hairs, so as to be undistinguishable to the sight. Of this tail, the Esquimaux of the northwest side of Hudson's Bay, make a cap of a most horrible appearance, for the hairs fall all round their heads, and cover their faces; yet it is of singular service in keeping off the musquitoes, which would otherwise be intolerable. The ears are only three inches long, quite erect, and sharp pointed, but dilate much in the middle; they are thickly lined with hair of a dusky colour, marked with a stripe of white. The frog in the hoof is soft, partially covered with hair, and transversely ribbed. The following sketch represents the under surface of the foot of the Musk-ox, the external hoof being rounded, the internal pointed. [Illustration] The foot-marks of the Musk-ox and those of the rein-deer are so much alike, that it requires the eye of an experienced hunter to distinguish them. The mark of the Musk-ox's hoof, however, is a little narrower. The food of the Musk-ox is the same with that of the rein-deer--lichens and grass; and sometimes twigs and shoots of willow, birch, and pine. At present this animal is not found in a lower latitude than 66 deg.; but formerly they came much further to the south; and their flesh used to be brought by the natives to Fort Churchill in latitude 58 deg.. It would appear that they are retiring northward, probably owing to the alarm created by the attacks made upon them by fire-arms. It is worthy of remark, that the American Bison has also retreated considerably to the north. According to Dr. Richardson, the Musk-ox inhabits the North Georgian Islands in the summer months. They arrive in Melville Island in the middle of May, crossing the ice from the southward, and quit it on their return towards the end of September.
