The young are produced alive in this class, which differs from all others 

 in nourishing the young with milk secreted by the mammary glands. 

 The thorax and abdomen are separated by a diaphragm composed of 

 muscles, which is used in respiration. Man, by his physical characters, stands 

 at the head of this class ; although from his moral attributes some naturalists 

 have denied him a place in the animal kingdom.
