HERPETIC AND BULLOUS ERUPTIONS. 147 



taken for farcy and even glanders. It is very important 

 not to confound it with such serious disorders, as it is a 

 mild affection, and rarely associated with constitutional 

 symptoms. Treatment consists in purgatives, low diet, and 

 the local applications to be preferred are alkaline and seda- 

 tive lotions. 



HERPES CIRCINATUS. VESICULAR KINGWORM. 



In the year 1841, a Dutch veterinarian, Heckmeyer, re- 

 corded a very remarkable case of vesicular ringworm in the 

 horse. It was observed by him, in the summer of 1837, on 

 a chestnut gelding, 13 years of age, the property of an army 



terinary surgeon. The previous history of the horse showed 

 he had suffered somewhat from derangement of the 

 tive organs. When Mr Heckmeyer saw the animal it 

 covered over the whole body with about two hundred 



tches of denuded hair, and here and there scabs were ad- 

 herent. The patches varied in size from a sixpence to a 

 crown-piece. On examining the eruption it could be readily 

 seen that exudation had occurred, so as to raise considerable 

 vesicles, which, in many places, had dried up so as to form a 

 scab of equal thickness over the whole surface. Wherever 

 the vesicles had formed, a circular portion of skin was 

 affected. On removing the yellowish-brown scabs, many hairs 

 fell off, and the skin was found beneath to be red and tender. 

 Slight friction over the scabbed portions of the skin seemed 

 to be agreeable to the animal, but there was not much itchi- 

 ness. The pulse was hard and full. The mucous mem- 

 branes red, fseces hard, urine brown and scanty, appetite 

 diminished, countenance dejected, and the horse appeared 

 lazy and dull. 



Heckmeyer considered the immediate cause of the erup- 

 tions to be plethora, and that the intense heat of the sun's
