and abrading and excoriating the surface. The croup may be 

 aUernately drooped and raised and the tail switched. These phe- 

 nomena are not abated by copulation, nor by time, like ordinary 

 heats, but will last for one or more weeks when a new set of 

 .symptoms set in. Meanwhile dull colicy pains cause restless 

 movements, arched back, frequent moving from place to place, 

 crouching by partial bending of the limbs, twisting of the hind 

 parts from side to side. The loins are tender to pressure, and the 

 middle of the flank to pressure or percussion. The mammary 

 glands are usually hot, swollen and tender. The genital erethism 

 may last from four to seven days. Then it subsides, with coinci- 

 dent improvement of the general symptoms and a recovery ensues. 

 Relapses are to be expected sooner or later. 



In fatal cases the erethism subsides, but fever, dullness and 

 emaciation continue, the case becomes aggravated at intervals, 

 weakness and exhaustion increa.se, decubitus may become con- 

 stant or paralysis ensue. The patient dies in marasmus in one to 

 three months. 



In some the genital erethism is absent from the first. There \s 

 dullness, prostration, anorexia, fever, hurried breathing, small 

 rapid pulse, colicy pains, tender abdomen, difficult defecation, 

 coated dung, a glairy (perhaps reddish or foetid; discharge from 

 the vulva, hot, tumid tender mammae, arched and sensitive loins, 

 and stiffness of the hind limbs. 



In all cases alike a rectal examination detects the ovary swollen 

 and exceedingly tender. 



Co2t>. The same general symptoms appear with characteristic 

 modifications. Restlessness, bellowing, pawing, inappetence, 

 arched, tender loins, swollen vulva with discharge, shiny and 

 perhaps foetid but without contractions, abdomen pendent and 

 flanks hollow and tender, udder turgid, hot and painful, move- 

 ments of the hind limbs stiff, halting, straddling. There is 

 greater tendency to salacious movements of the croup. The 

 diagnostic feature is palpation of the ovary through the rectum. 



In chronic cases more or less of the above symptoms are shown 

 in a greatl3' mitigated form, but oftentimes there are long inter- 

 vals of apparent health. Palpation through the rectum is the 

 final test in this as in the more acute cases.
