HERBIVORES, OR PLANT-EATERS. 27 



them, coming at call, and performing curious feats ac- 

 cording to their master's directions. A few years ago, 

 in a large tank of sea-water in the Aquarial Gardens 

 at Boston were two Seals called "Ned" and ^Fanny," 

 which were so tame that they would come to the keeper 

 at call, and allow him to handle them, would shoulder 

 a miniature musket, turn the crank of a hand-organ, 

 shake hands with the by-standers, and "Ned," especially, 

 would even "throw a kiss" to the ladies. Seals feed 

 upon fish, and always eat in the water. They are from 

 three to twenty feet long. The Walrus has a body as 

 large as the largest ox, and is covered with short brown 

 hair. Two of its upper teeth, the canines, or eye-teeth, 

 grow to be tusks two feet long. These tusks assist in 

 climbing upon the ice-banks, and serve as a means of 

 defence, and to aid in securing food. 



HERBIVORES, OR PLANT-EATERS, OR HOOFED 

 ANIMALS. 



These are mammals which feed wholly upon vegeta- 

 tion, and which have hoofed feet, and use their limbs 

 only for standing, walking, and running. Some of 

 them, as the Deer, Antelopes, Sheep and Goats, and 

 Oxen, have the foot divided or cleft, forming an even 

 number of toes ; and all herbivores of this sort chew the 

 cud, and from the latter fact are known as Ruminants, 

 a name which means cud-chewers. Others, as the Horse 

 and Ass, have only one toe to each foot, and are hence 

 called Solipedes or Solid-hoofed animals. Others, as 

 Elephants and the Mastodon, have five toes, and a long 

 flexible snout or proboscis, and from the latter fact are 

 called Proboscidians.
