TAIL. 261 



drivers. The operation of ovariotomy will generally cure 

 such animals of this disease (nymphomania). Almost all 

 Arab horses, and certain horses in all countries, keep 

 the tail rigidly fixed to one particular side, near or off, 

 when walking, unless, indeed, to use it when occasion 

 demands. English thorough-breds, however, at the same 

 pace, generally swing it from side to side in an easy, free 

 manner, somewhat similar to that in which a fast and fair 

 walker uses his arms when going along at, say, the rate 

 of six miles an hour. The difference, here, seems to be 

 due to the thorough-bred's longer stride and greater free- 

 dom of action.
