 Vpon the Teeth of Elephants in general ; their Structure, 

 * Growth, Succession, and Differences, with respect to Age 

 and Position. 



J- HK manner in which these teeth grow and succeed each 

 other is so extraordinary,they present in their various states, 

 figures and sizes so variable, that it is not astonishing they 

 have been so often mistaken. 



We have made the following observations upon the two 

 Indian elephants we had occasion to dissect ; but we ought 

 to acknowledge that we were guided by the excellent work 

 of our colleague, M. Tenon, upon the teeth of the horse. 

 Anv thing peculiar we have seen in those of the elephant 

 belongs only to their size and to their peculiar configura- 

 tion. 



We ought also to acknowledge that excellent observations 

 have been already made upon the particular subject of the 

 teeth of the elephant bv M, Pallas f, Peter Camper and his 

 son Adrian ti J^Iessrs. Corse, Home§, and Blake ||: these 

 three last, in particular, have almost exhausted the subject, 

 each of them having of himself discovered some importaiU 

 facts. 



As to the manner in which teeth in general arise and 

 grow, our observations seem to us to confirm the theory of 

 Hunter rather than that of any other author, in so far as 

 regards that part of the teeth which has been called the os- 

 seous substance. But this great anatomist does not seem 

 to us to have been equally happy as to the enamel ; and he 

 has entirely mistaken the nature of the third substance, pc-
