hind paw. Each pad consists of a mass of fibrous tissue and fat, 

 and a large trilobed one is placed beneath the ends of those bones on 

 which the animal rests in walking, as represented in the figure here

 CELLS, MAGNIFIED 300 DIAMETERS. 



A number of cilia are seen on the flattened 

 superficial end of each cell, which also con- 

 tains a nucleus with a nucleolus.

given. But, as before observed, the skin does not clothe the exterior 

 of its body only ; at the margin of the lips it is reflected inwards, 

 lining the mouth and continuing onto line the whole alimentary canal, 

 and it also lines all the other passages which open on the exterior of 

 the body. The cat's body may thus be compared with a ring-shaped 

 air-cushion which has been very much drawn out on each surface, 

 the central vacant space being also greatly prolonged, but contracted 

 in diameter to represent the alimentary canal.
