PREVENTION, SYMPTOMS AND TREATMENT ^9 



liquor, potassae, 3iv, olei olivse, giiiss. The squeezing of pus from 

 all pustules, as soon as they appear, is an important part of the 

 treatment in evacuating the mites. The mites may be discovered by 

 a magnifying glass in this pus, or in scrapings of the skin in the 

 scaly form. 



Recently the daily injection of a 2 per cent, carbolic acid solu- 

 tion through a fine needle about and in the pustules has been used 

 and cures have been reported after two weeks of this treatment. 



Masturbation — Onanism. 



This bad habit may be cured by enforcing proper exercise, or 

 work, and light diet; by punishment (it is reported that a stallion 

 was cured by being made to stand two hours daily in cold water 

 for two weeks) ; by permitting a proper amount of coition; and, 

 finally, if all else fail, by performing castration. Dogs and rams 

 and, less commonly, bulls and stallions are afflicted with this habit. 



Metritis, Acute and Chronic. 



Acute metritis is commonly due to traumatism and infection 

 during or after parturition. It begins as an endometritis ; metritis 

 and perimetritis are sequels. There may be loss of appetite and 

 flesh and vaginal discharge. The speculum is essential to make a 

 diagnosis. Local inflammation and erosion of the cervix (Endo- 

 cervicitis) occur first; the womb is enlarged and tender in metritis 

 proper, and fixed by inflammatory exudate, so as not to be freely 

 movable, in perimetritis. The condition differs from puerperal 

 fever, or septic metritis, in being unaccompanied by high fever or 

 symptoms of general infection. Acute metritis often becomes 

 chronic. In either form there may be contraction of the os with 

 retention of secretion in the womb. 



Treatment. — This is purely local and requires considerable 

 time and professional care, so that the expense usually contra- 

 indicates it. The animal may, however, recover spontaneously at
