GLASS EYES. 



Horses sometimes have one or both eyes of a glassy 

 appearance and gree«iish colour, with the pupil or 

 sight of one detenainate shape : such an eye is bHnd, 

 however deceptive it may appear. The disease arises 

 either from blood thrown over the retina, or from a 

 palsy of this nervous expansion. Sternutatories, or 

 sneezing powders, have been used, and stimulating 

 applications, as brandy, gall, &c. introduced within 

 the eye ; but the benefit derived has seldom been 

 considerable. Dogs now and then have a similar 

 complaint : a remarkably handsome pug, in my posses- 

 sion at this time, labours under it. 



FARCY. 



Farcy and glanders have some connection with 

 each other; but how much, or of what nature, it is 

 difficult to say. Farcy is, however, more worthy of 

 notice in this place, as it is sometimes curable. 

 Farriers have long supposed it a disease of the veins ; 

 but it proves to be a disease of what we have spoken 

 of as the absorbents of the body. The absorbents 

 of the skin follow the track of the veins, and henee 

 farriers thought the disease had this seat. Every 

 one ioiows that farcy appears in tlie form of small 

 buds, which are first hard and indolent, and then 

 burst, and discharge a thin watery matter, and at 

 last degenerate into extensive ulcers. It appears to 

 be both caught and generated : wliile it confines it- 

 self to the skin alone, the horse lives ; but when it 

 degenerates into glanders, or attacks the lungs, it 

 soon produces its fatal effects. While it is confined 

 only to the buds, even though they should run mat-
