LICE. 387 



CASE applied to both farmers and their butchers, neither of whom 

 seemed to approve the idea which he had conceived of their pigs 

 being lousy, but referred him to those of the Emerald Isle as 

 being sure to gratify his wishes, forgetting that the Irish pigs 

 come to this market to meet English buyers. He accordingly 

 visited a colony just arrived, when he most certainly met with a 

 ready supply; but here they were confined almost entirely to 

 lean animals, and wherever he found a pig fat and healthy, 

 no parasites were to be seen. In walking, this species uses the 

 claw and tibial tooth with great facility, which act as finger and 

 thumb.

This is said by Denny, in his great work on this subject, to 

 have been taken only on the calf. It seems, however, very un- 

 likely that a particular species could be restricted to the young 

 of any animal ; but the figure given by Denny is too unlike that 

 of the ox (H. eurystemus) to allow us to suppose it an abnormal 

 or exceptional variety of it.
