 his fore legs or upon the manger, will not move or lie down, 

 breathing quick, panting-like. The nostrils are expanded, the head- 

 thrown forward ; the countenance expresses pain and great pros-

 exposed to cold draughts, he is seized with a trembling fit ; the ears 

 are cold, and the respiration hurried, when the ear applied to the 

 chest can plainly detect the imperfect breathing. 



The inability of the horse to take sufficient air into the lungs, 

 causes great and rapid prostration, and the horse will often, from 

 extreme pain, lie down and get up, resembling colic (Summerville) ; 

 but the coldness of extremities, prostration, and condition of pulse, 

 will, if carefully examined, enable an understanding of the real
