2, Comparison of the Tusks. 

 We are unable to ascertain with precision, whether or not there 

 existed the same differences between the fossil and the Indian ele- 

 phant, with regard to the tusks of the different sexes, and the different 

 varieties, as the fossil tusks are in general found isolated, and as a suf- 

 ficient number of perfect skulls have not been discovered, to enable 

 us to sav whether or not there were adults without lon^ tusks.
