chills, dullness and other phenomena, which belong in gen- 

 eral to acute contagious fevers. The fever appears very sud- 

 denly, usually ranging from 103 to 105° F. although it may 

 exceed this. Generally speaking, the temperature is higher 

 than in influenza and lower than in the contagious pneu- 

 monia of the horse. The pulse is hard and full and some- 

 what quickened; respiration is not very greatly disturbed. 

 Cough is present, though this does not constitute a very 

 prominent symptom of the affection. 



Early in the disease there is a manifestation of pain in the 

 limbs, which is shown by shifting of the weight from one 

 foot to another while the animal is standing and by great 

 stiffness and soreness when forced to move, the movements 

 being accompanied by a cracking sound in the joints. After 

 a time the legs begin to swell, commencing at the feet and 

 extending upward until at times the body is affected. This 

 tumefaction has its chief seat in the subcutaneous connective 

 tissue and is at times very great. As the swelling of the 

 limbs increases, the pain in them tends to abate and at the 

 same time the fever begins to decrease. 



The alimentary tract is greatly disturbed. At first there 

 is a very marked tendency to constipation, in which the feces 

 are covered with large quantities of mucus and their color 

 considerably altered. Defecation causes some pain and 

 straining. Later there is a tendency to diarrhea, which is 

 easily and often fatally intensified by the administration of 

 purgatives, especially of aloes. The conjunctiva becomes 

 bright pink, swollen and edematous. At times the conjunc- 

 tivae are so badly swollen that the eyelids become somewhat 

 everted and the edematous membrane pushed out between 

 them. The eyes are very sensitive to light and the animal 

 attempts to keep them closed. There is a profuse secretion 

 of tears, which flow down over the cheeks. The cornea is 

 frequently clouded, so that vision may for a time be inter- 

 rupted. There is some tendency toward pleurisy, pneumonia 

 and other pulmonary complications. 



From a breeding standpoint, the chief interest lies in the 

 complications of the genital organs. The breeding stallion
