 structure is, and we will now point out a few of the 

 differences which exist between mankind and other 

 animals. 



The structure of the teeth, and the form and size 

 of the intestines in man, differ considerably from 

 those of the inferior animals. These are so con- 

 structed as to be fitted for the kinds of food which 

 are taken by human beings. 



The teeth have the enamel all on the outside ;

 matter, the top of the teeth is broad and uneven, 

 and has ridges of enamel mixed with the bone. 

 This enables them to grind their food ; for the 

 softer bone wears away, and leaves the teeth very

 the enamel. 



The stomach and intestines of these gramini 

 vorous, or grass-eating, animals, also differ from
