We are indebted for the knowledge of this animal (_fig. 219._) to M. de la Condamine, and shall therefore give his account of it in his Voyage up the river Amazon. "The monkey, of which the governor of Para made me a present, was the only one of its kind that had been seen in the country. The hair on its body was of the most beautiful silvery white colour: and that on its tail was of a glossy chesnut approaching to black. Its ears, cheeks, and muzzle, were tinctured with so bright a vermilion, as to have the appearance of being the work of art. I kept it a year, and it was alive at the time I was writing this account, almost within sight of the French coast; but, notwithstanding the continual precautions that I took to preserve it from the cold, yet the rigour of the season killed it before my arrival. I preserved it in aqua vitæ, which will prove my description is not exaggerated." By this recital of M. de la Condamine, it is obvious that his description will apply to no other animal than the mico; and that it is a different, and probably, scarce species, since no author or traveller before him has made any mention of it, though it is remarkable for the bright red which animates its face, and for the beauty of its hair. _Distinctive Characters of this Species._ The mico has neither pouches on the side of his cheeks, nor callosities on his posteriors. He has a flaccid tail, which is about half as long again as the head and body. The partition of the nostrils is not so thick as in other sagoins, but their apertures are at their sides. His face and ears are naked, and of a vermilion colour. The muzzle is short, the eyes are distant from each other; the ears are large; his hair is of a beautiful silver white colour, and of a glossy brown on the tail. He walks on all fours, and is about seven or eight inches long. The females are not subject to the periodical emanation. ACCOUNT OF SOME ANIMALS NOT EXPRESSLY TREATED OF IN THIS WORK. We have now finished, to the utmost of our ability, the History of Quadrupeds, but in order to render it still more complete, we shall not pass over in silence those of which we have not been able to obtain an exact knowledge. They are but few, and of those few, many must be looked upon as varieties of those species we have before mentioned; yet feeling it as a duty to state all we knew, or could gain a knowledge of, in the animal kingdom, we determined to add the following, and in which we have been as particular as possible. 1. THE WHITE BEAR.
