234 Management and Treatment of the Hoi'se. 



and totally free from all opacity or cloudiness 

 over its entire surface. As I have said before, 

 the best method of examining the eye of the 

 horse is to place the cheek of the scrutinizer close 

 to the cheek of the horse, both behind and under 

 the eye. The latter position is the most advan- 

 tageous to see it thoroughly. The open air is 

 not favourable for the examiner (hence dealers, 

 knowing the horse has defective vision, are always 

 anxious to bring them out to the light). The 

 head of the horse should be a little within the 

 door of the stable, and, by looking outwards, any 

 defect is rendered more visible. If any faint, 

 whitish, milk-like streaks be noticed passing over 

 the cornea, it is certain the animal has had 

 inflammation in that portion of the eye ; but 

 should the centre part of the cornea be perfectly 

 transparent, and yet the margin of it where it 

 unites with the sclerotica have a hazy ring, it 

 may be concluded that this has been occasioned 

 by recent inflammation, and consequently the eye 

 is predisposed to a return of it. During the 

 operation of thus inspecting the eye, mind that 

 no white or pale-coloured object be near, as its 

 form and great transparency are very likely to 

 reflect these rays, and deceive the person making 

 the examination. Attention to the ^dilation and 

 contraction of the pupil will materially aid a 

 person in the detection of blindness or otherwise. 

 When the cornea and crystalline lens are quite 

 transparent, with the retina paralysed, and of 

 course not liable to be afi'ected with the light, it 

 is extremely difficult to detect blindness either
