 great resemblance to the human nails, for which 

 ration these animals have sometimes been called 

 Quadmmane$i as having four hands, rather than 

 four feet*. In some tribes of Mammalia the feet 

 are armed or shod with strong hoofs, either quite 

 entire, or cloven or divided. In such of the Mam- 

 malia as possess the power of flight, as in the Bat 

 tribe, the fore-feet are drawn out into slender fin- 

 gers of an immoderate length, and united by a 

 common membrane or web. In some of the 

 aquatic Mammalia, as the Seals, for instance, both 

 the fore and hind feet are very strongly or widely 

 webbed; and in the Whales, there are in reality 

 only two feet, the bones of which are inclosed irt 

 it are commonly-ailed the fins, while the lobes 

 of the tail in some degree answer the purpose of a 

 pair of hind-feet, but consist merely of strong
