Purpura or Spotted Fever, 177 



with blood. The urine is dark colored and has a strong 

 smell. 



The more severe symptoms are remittent in their charac- 

 ter ; they may appear very threatening one day, seem almost 

 gone the next day, but return with the same or greater vio- 

 lence. Therefore the physician should be cautious Low he 

 pronounces the animal decidedly better. 



Treatment. — It is of first importance to remove the ani- 

 mal to a clean, well drained, well ventilated stable. Purga- 

 tives are dangerous and bleeding as good as fatal. What is 

 wanted is to relieve the bowels when there is constipation or 

 irritation by a free injection or by a moderate dose of oil ; and to 

 administer something which will check the action of the poison 

 on the system. The most successful of all drugs for this 

 purpose is chlorate of potash j for the discovery of the appli- 

 cation of which in this disease we have to thank Prof. Wil- 

 liams. He gives half an ounce at a dose, and repeats it twice 

 in the twenty-four hours. A larger dose must not be given, 

 as it is liable to cause irritation of the bowels. Under this 

 medicine the results are most satisfactory ; the swellings 

 rapidly diminish, and restoration to health ensues, in the 

 great majority of cases. 



The treatment preferred by Mr. Chawner is one to act on 



the kidneys and keep up the strength. He prescribes : — 



No. 188. Solution of acetate of ammonia, 2 oz. 



Oil of turpentine, 

 Tincture of chloride of iron, each 1 oz. 



This amount, in a pint of gruel, three or four times a day. 



Or instead of this : — 



No. 189. Sulphate of iron, 

 Powdered gentian, 

 Powdered camphor, 

 Nitrate of potash, each 2 dr. 



For one ball, to be given night and morning. 



The swollen parts may be bathed with vinegar and water,
