180 ■ INJURIES 



tlie cornea, and, through the simultaneous twinkling are 

 carried under the upper lid ; where the particle may stick 

 with so much pertinacity, that its extraction is a difficult 

 operation. The way to remove it, is to seize the upper eye- 

 lashes with the right hand, while the left impresses and 

 fixes the lower lid ; then, to elevate the former, so as to see 

 underneath it. Should this not succeed, we must evey^t the 

 upper lid : an operation which is not difficult — providing the 

 horse be secured, and the operator be expert — and one that 

 will enable us to discover any foreign body. 



Cuts and Contusions do occasionally reach the globe 

 of the eye. They then cause much inflammation, and 

 require active treatment. The most formidable cases are 

 those in which the cornea is penetrated, allowing the 

 aqueous humour to escape, and the iris to protrude. Violent 

 inflammation supervenes ; the lids are closed ; and the 

 animal experiences such pain, as to resist having them 

 opened. We can do little more in the first instance than 

 bleed ; exhibit a purge ; and use anodyne fomentations — 

 warm water in which poppy heads have been l)oiled. As 

 soon as the physic begins to operate, we may probably 

 succeed in separating the lids. Should we find the iris 

 protruding, it will be proper to return it. This must be 

 done with care because of its importance as a portion of the 

 eye and because of the high sensibility it has acquired 

 through friction and exposure. After this, healing eye- 

 washes^ may be used to unite the parts. These should be 

 gently applied by means of a soft camel's hair pencil, and 

 the eye should ])e shaded during the time of treatment which 

 should consist of a gentle course of mercury.

These parts, from abuse and mismanagement, sometimes 



become cut, contused or lacerated. Horses that have 



suffered injuries of this description, slaver at the mouth,
