:J3 ON THE EYE. 



by the hand to examine the state of the eye, the 

 membrana nictitans or hawe is brought, by the 

 animal, considerably over the surface of the eye, 

 to supply momentarily the office of the eye-lids,

This temporary appearance of the hawe the 

 farrier mistakes for a disease, and generally re-

 and superficial irritation produced by these means, 

 sometimes relieve the eye ; but the subsequent 

 effects is an exposure to inflammation, created 

 by the presence of any extraneous substance, 

 such as dust, hay-seeds, &c. which, from the 

 loss of the hawe, the animal is disabled from 

 wiping away.
