RINGWORM. 



Eingworm is a malady of the skin which occasionally pre- 

 vails 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 wiU. 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 succes- 

 sion 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 appear- 

 ance I have on several occasions observed, and has led me to 

 the opinion that Eingworm is an endemic disease. 



Symptoms. — The symptoms of Eingworm wiU. be illustrated 

 the best by detailing the appearances presented by an indivi- 

 dual 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 vertebrse ; and upon the hind quarters. Each of 

 these spots is about the size of a shilling.
