the Human Kind and other Animals. 283 



tie from reading. It seems that it very frequently oc- 

 curs in human births ; but Mr. Blumenbach does not 

 know, that it has ever been observed in the fetal ani- 

 mals of any other mammalia. The professor even at- 

 tempts to account for its non-occurrence in the class of 

 animals*. 



Prolapsus of various kinds are frequently met with 

 among dogs, hogs, and other animals. In the first of 

 these animals, the Prolapsus of the rectum is a com- 

 mon affection. The same animal and the hog are liable 

 to Hernias : particularly, I think, to Umbilical Hernias. 



Herpes, of different kinds, are not unknown among 

 the mammaliaf. Even Tinea capitis, or at least a dis- 

 ease extremely allied to it, afflicts the dog, and other 

 animals. These diseases in the mammalia are often 

 cured by the same mercurial and other medicines, 

 which we employ for their cure in the human kind.
