different forms; their blood is white; they have trachea*, 

 and breathe by ftigmata : 8th, worms, of which he reckons 

 1,159 ; their heart is of different forms, their blood is white, 

 and they have no apparent entrance for the air. 



Cuvier and Geofl'roy have made feveral intereffing re- 

 fcarcbes in regard to that clafs of animals called mammalia. 

 The former, in a memoir on the rhinoceros, has proved that 

 the two kinds known by Camper, viz. that of Alia and that 

 of Africa, may have one, two, or three horns. The horns, 

 therefore, cannot be a characlcrifmg mark to diftinguifh 

 them. The diftinguifhing mark, however, of the African 

 rhinoceros is, that it has only twenty-eight denies molares, 

 while that of Afia has twenty-eight molarrs and fix hiciforcs. 

 He is of opinion alto, that, there are at Ieaft two other fpe- 

 eies in exigence, and perhaps a third. 



Camper has proved alio, that the African elephant is dif- 

 ferent from that of Alia. The teeth of the latter are com- 

 plied of tranfvciial zones, and thole of the African elephant 

 reprefent on their iurfaee a, kind of trefoils or lozenges. It 

 appears, that beiides thefe two fpecies there exiittwo others, 

 and perhaps three. Swcdianr fays, that the greater part of 

 the elephants' tniks ufed in commerce are collected in the 

 umnenfe paltures of Africa, where thefe animals feed, and 

 that the negroes let fire to the meadows in order to difcover 

 them. 



Audibert propoles to give a hiftory of apes. He has al- 

 xtady publifhed one number, containing fix coloured plates, 

 {oho lize.
