the refraction of the rays of light constantly beaming into the 

 eye will stimulate the nerve too much, and is apt to produce 

 exhaustion of energy in the optic nerve and retina. If the 

 stable is well provided with windows, the walls should be 

 painted of some subdued tone of colour ; and when other- 

 wise, white should be used.

This with the horse, as with man himself, is of para-

 medium quantity, and increased a little daily ; but those 

 who faticfue or even drive a horse hard when in full condi-
