EINGWOEM. 



Eingworm is a malady of the skin which occasionally prevails 

 somewhat extensively. 



The disease is generally manifested upon horses during the 

 summer months of the year ; and from the manner of its 

 appearance, I am of opinion that it arises from causes of an 

 endemic nature. The facts which have led me to form this 

 opinion, I will briefly state. At times I have been three years 

 in succession without seeing a case of the disease; then a 

 solitary one would be brought for treatment, which upon every 

 occasion of the kind would be speedily followed in rapid 

 succession by numbers of others from various parts of the 

 country : after which, the disease would suddenly cease and not 

 be seen by me again, for at least a similar period of time to 

 what I have stated. This peculiarity, in connection with its 

 appearance I have on several occasions observed, and has led 

 me to the opinion that Eingworm is an endemic disease. 



Symptoms. — The symptoms of EiDgworm will be illustrated 

 the best by detailing the appearances presented by an in- 

 dividual case of the disease. 



I. — Existing here and there upon the skin of the 

 animal, are a number of round spots. They are present on 

 both sides of the neck, and upon the left cheek ; — also upon 

 the sides of the shoulders ; upon the back, in the region of 

 the lumbar vertebra? ; and upon the hind quarters. Each of 

 these spots is about the size of a shilling.
