278 On the Strata of the Dddb Alluvium. [Mat, 



P. S. I have found on comparison that I had come to wrong conclu- 

 sions, with respect to some of the vertebrae, I had the honor to send 

 with the last parcel, of which opportunity I availed myself to send all 

 cf which I had the least doubt. The teeth too, which I have hitherto 

 called camel's, cannot have been rightly classed, as they bear 

 not the least appearance of having belonged to the existing species, at 

 least, the evenness of the crown differs entirely from any anatomical 

 specimen to which I have access. 



I should have forwarded the whole of the undermentioned speci- 

 mens before, but obvious reasons induced me to wait the present op- 

 portunity.

Note. — We intended to have given plates of the principal fossils forwarded by 

 Serjeant Dean, but the friend who had kindly undertaken to draw them has 

 been prevented from accomplishing his task in time ; we must therefore reluc- 

 tantly postpone their insertion and notice. — Ed.
