 I have noticed that its natural colour is white; 

 where it is found of a red colour, without any- 

 apparent signs of local injury, such as tenderness 

 and swelling, it is a symptom of inflammatory dis* 

 ease : if instead of red, a yellow tinge predominates,

 the horse. 



If an excess of tears should be observed, it de- 

 notes a general debility of the organ, and should 

 occasion a more than usual scrutiny. 



But the principal object is to ascertain if the 

 sensibility of the eye is affected : this is discovered 

 by carefully noticing whether the pupil expands 

 and contracts to a perceptible extent on approach- 

 ing the light. London stables are usually dark, 

 and when the horse is examined in the stable, the
