 been completed. 



The female in this group of Jackals has been placed in a very

 ing as she is her frolicsome progeny, two or three of which are 

 engaged in assisting in the despoliation of the victimized fowl.

 accomplished. 



In making the model over which the skin is subsequently fixed, 

 the same principle and the same material is followed and used as 

 was described in the case of the Sunfish. But in the mammal, a

 Figs. 124 and 125. These muscles I have carefully examined in 

 the photographs, and find that they have been reproduced with

This is the only way that perfection can be attained : We must

 ments before the skin is removed; we must take afterward casts 

 of the carcass and make other photographs, and take plenty more
