By this description we find that the manati of Senegal does not differ in any particular from that of Cayenne; and from a comparison made of the head of the Senegal manati with that of a foetus of the Cayenne lamantin by M. Daubenton, he presumes that they are of the same species. The testimony of travellers also agrees with our opinion; Dampier in particular speaks positively, and his observations deserve a place in our history. "It is not only in Blewfield river, which springs between the rivers Nicaraga and Veraga, that I have seen the manati: I have also seen them in the Bay of Campeachy, on the coast of Bocca del Drago, and Bocca del Toro, in the river of Darien, and in the small southern islands of Cuba: I have heard it said that there are a few found on the north of Jamaica, and many in Surinam river, which is a very low country. I have likewise seen them at Mindanea, one of the Philippine islands, and on the coast of New Holland. This animal is fond of brackish water, therefore he most commonly inhabits those rivers which border on the sea. This is possibly the reason why we never meet with any in the South Seas, where the coast is generally high, and the water very deep near land, except in the Bay of Panama; but even there the manati is not to be met with; but the West-Indies being, as it were, a great bay composed of a number of small ones, are generally low land and shallow water, and consequently afford a food which is agreeable to the manati. They are sometimes seen in salt water, sometimes in fresh, but seldom very far from shore. Those which inhabit the sea, and places where there are no rivers that they can enter, come to the mouth of the nearest fresh-water rivers which they find, once or twice in twenty-four hours. They feed on a narrow herbage which grows on the sides of the shores, especially in places where the tides or currents are not very strong. They never go on shore, but always keep in a depth of water where they can swim. Their flesh is sweet, and very good food; their skin is also of great utility. The manati and the tortoise are commonly found in the same parts of the world, and feed on the same herbage."[K] [Footnote K: A great number of manatis are to be found along the low and marshy coasts, and in the vast lakes of Moyacaré, the most southern part of French Guiana, above the Oyapoc. Small vessels from Cayenne go to the fishery of these animals, and bring their flesh salted, a gross aliment which is kept for the negroes. This fishery, which might become an object of important commerce, should be encouraged; it would require a small establishment upon the coast, and would facilitate the means of acquiring some knowledge of a country now unknown, and which, at the same time that it opened new sources of commerce, would prove also an inexhaustible mine of wealth to Natural History.] THE NOMENCLATURE OF APES.
