I shall here give a brief statement of the facts and argumenis 
which have been adduced in support of the theory that the 
Mammoth lived and died where its remains were found. For 
these facts I am mainly indebted to the admirable papers by 
Mr. Howorth on the Mammoth in Siberia, which appeared in 
the Geological Magazine for 1880, 
d the remains of the Mammoth been carried down from 
the far south by the Siberian rivers, they would have been 
found mainly, if not exclusively, on the banks of the long 
rivers, such as the Obi, Yenissei and the Lena, and in the 
deltas formed at their mouths. But such is not the case

parts would certainly hinder the growth and full development 
of the animal.
