The horse to have only seven pounds of hay each day, 

 during the time, and when the purgative commences to 

 operate, give two ounces oil of turpentine in half a pint 

 of luke-warm water, in a drench, and trot the animal for 

 five minutes. 



CLA.SS IV. 



OPHTHALMIA — GUTTA SERENA INFLAMMATION OF THE EYE — 



DEAFNESS LOCKED JAW. 



Ophthalmia, or Mood Blindness. 



Should four days pass, and the inflammation not be 

 abated, we may begin to suspect that it is the ophthalmia, 

 especially if the eye is very impatient, and the cornea 

 clouded. The humour often loses its transparency, even 

 the iris changes its color, and the pupil is exceedingly 

 contracted. The veterinary surgeon has now an ob- 

 stinate disease to combat, and one that will generally 

 maintain its ground in spite of all his effoits ; for two 

 or thi'ee weeks the inflammation will remain un- 

 diminished, or if it appears to yield one day, it will 

 return with redoubled violence on the next. At length, 

 and often unconnected with any of the means that have 

 been used, the eye begins to bear the light— the red- 

 ness of the membrane of the lid disappears, the cornea 

 clears up, and the only vestige of disease which remains 

 is a slight thickening of the lids, and apparent uneasiness 

 when exposed to a very strong light.
