 From hence proceed the various species of disorders to 

 which an animal is exposed : among these maladies, 

 there are some which attack only the skin, and produce 

 spots of various colours, wrvikles^ pustules, pimplts '

 nourishment of them to their own benefit, or alter the 

 constitution of them : others are caused by the change
