3, 4. Longitudinal view of the tusks i-epresented laterally 

 in figs. 1, 2. They both possess the same double 

 curvature as the tusks of the great fossil elephant in 

 the Museum at Petersburgh from the icy cliff at the 

 mouth of the Lena, in Siberia. 

 This curvature is very frequent but not constant in 

 fossil tusks ; it occurs also sometimes in tbe tusks of 

 recent elephants : there is a similar double curvatui-e 

 in the recent tusk of a small elephant from Ceylon in 

 the possession of the Earl of Carnarvon, at High- 

 clere, Hants.

of elephant.

8. Scapula of elephant.

 Fig. L Head of a boss urus, in precisely the same condition 

 with the fossil bones of elephants, and very different 

 from the state of the head of a musk-ox with the 

 external case of the horns still attached to it, which 

 was brought home with the fossil bones, and was 

 found with them on the beach at the bottom of the 

 mud cliff in Eschscholtz Bay, but is so slightly de- 

 cayed that it seems to have been derived from a 

 carcass that has not long since been stranded by 

 the waves. TJiis head of a musk-ox is not en- 

 graved, as it cannot be considered fossil. 



2. External horny case detached from the bony core of 



the horn of an ox : it is in a state equally fresh with 

 the head of the musk-ox j ust mentioned ; and, like it, 

 appears to be derived from an animal recently cast 

 on shore. 



3. Femur of an ox. 



4. Tibia of an ox. 



5. Metatarsus of an ox.
