Thus, when M. Camper opposes to my theory the tooth 

 of a living elephant with thin laminae, and another with 

 thick laminae, it is because the first he has represented, 

 pi, xi.v. fig. 2. of his work, has only ]2 laminae, and pro- 

 ceeds from a young elephant ; and because the other (/Zf. 

 fig. 6., as well as that in p!. xiii. fig. 4 and 5) has 23, and 

 belongs to an old animal. It is only necessary to compare 

 together some teeth with tlie same number of laminae. 



It results from this first character, (the narrowness of the 

 laminK,) that the number of these laminae, whick serve at 

 once for trituration, must have been more considerable in 

 the fossil elephant than in the elephant of India. 



Corse says expressly, that this last has scarcely more than 

 ten or twelve in action at once, and we very often find fos- 

 .sil teeth which have their twenty-four teeth worn: such is 

 that from the forest of Bondy, represented in pi. vi. fig. 1, 



A second character which docs not appear less sensible is, 

 that the lines of enamel which intersect the cuts of the la- 

 jninae are thinner and less festooned in fossil teeth than in 

 others. I remark this in all the specimens of our mu- 

 fcum, one only excepted, of which I shall speak below.
