COLLECTION OF MAMMALIA. 325 



The four following cases contain nineteen 

 species of the order pachydermata. The Arabian 

 horse, the baskir horse covered with long hair, 

 the zebra, and the quagga, are remarkable for 

 their beautiful form or variety of colours. The dif- 

 ferent species of wild boar are placed between 

 the legs of these larger quadrupeds, and amongst 

 them the Pecary of America, which has a glan- 

 dulous opening in the back, whence issues a 

 foetid humour. 



In the last case are the cetacece, vulgarly called 

 blowers. A foetus of the whale, a porpesse, a 

 large dolphin, and the dolphin of the Ganges, a 

 very rare species sent by MM. Diard and Duvaucel, 

 are the most remarkable animals of this order in 

 the Museum. 



We have been obliged to place in the middle 

 of this room, on account of their enormous size, 

 the male and female elephants, which lived in our 

 menagerie ; as also the one-horned rhinoceros of 

 India, which lived at Versailles ; the two-horned 

 rhinoceros of Sumatra, and the unicorn of Java, 

 which we owe to MM. Diard and Duvaucel ; and 

 lastly, the two-horned rhinoceros and the hippo- 

 potamus, brought from the Cape by M. Delalande. 



and the birds. The monotrema in fact differ from mammalia in the 

 want of mammae, and by being oviparous, but they approach them in 

 the other organic systems.
