Purpura Hsemorrhagica. 



This is an eruptive, non-contagious, intermittent fever, 

 characterized by petechise on the mucous membrane, and 

 by elevations of cutaneous tissue. It is generally a sequel 

 to debilitating diseases, e.g., influenza, catarrhal fever, and 

 strangles. Purpura may also occur as a result of defective 

 ventilation, bad drainage, and poisonous effluvia. Anti- 

 septics, such as salicylic acid or chlorate of potassium, may 

 be tried. The salts of ammonium are to be avoided. 

 Astringents, e.g., ergot of rye, tannin, and tincture of 

 perchloride of iron, are of great value, as also are alcohol 

 and vegetable tonics. If sores be present, they may be 

 dressed with antiseptic lotions, and if the head be greatly 

 swollen, foment with warm water, but do not incise the 

 swellings.
