496 The Ohio Naturalist. [Vol. IX, No. 6, 



fat. 127 grams were removed from other portions of the body in 

 pieces of varying size. The whole amounted to 627 grams or 

 more than one-sixth of the weight of the body. In view of the 

 presence of fat in thin sheets between the muscles and over them, 

 a conservative estimate would be that the amount of fat stored 

 for use during the winter's cessation from activities was more 

 than one-fourth of the total weight of the animal. 



In our common hog, which does not hibernate, the thickest 

 layer of fat is likely to be over the shoulders — the most- exposed 

 portion. 



It would be interesting to learn the conditions in other ani- 

 mals, such as the bear, which hibernate. In this case it is plain 

 that as the raccoon curls up in the hollow tree with his nose 

 between his hind legs and his tail over his head and shoulders, the 

 rump and back make the less protected part of the circle. Hence 

 the location of the heavy fat blanket in that region.
