AND HIS DISEASES. 173 



disease of the left eye. Gn looking into the eye, the trae 

 nature of this phenomenon could be plainly seen ; the worm 

 appeared to move in every direction, and with remarkable 

 quickness. We recommended its removal from the eye by 

 an operation, and immediately brought the horse to our in- 

 firmary. He was cast in the usual manner ; and with a 

 -smaU lancet we made an incision into the antero-inf erior part 

 of the cornea, allowing the aqueous humour to escape, and 

 with it the little worm, wnich measured one and a-half inches 

 in length, and was thickest in the middle, tapering towards 

 either extremity. After the operation the eye was covered 

 with a cloth saturated with cold water, a dose of purgative 

 > medicine administered, and three days afterwards he was put 

 to his usual work. 



FUNGUS H^MATOIDES, OR BLEEDING FUNGUS. 



The mucous membrane of the eye is occasionally the seat 

 of cancerous deposits. They are generally rapidly developed, 

 and are largely supplied with blood-vessels, which are readily 

 ruptured by the least ^pressure, hence the name, " bleeding 

 fungus." 



These tumours are very often the result of some injury to 

 the eye, and sometimes grow to an enormous size ; we have 

 met with eases where the fungus extended half-way down the 

 cheek, giving the animal a very ungainly and most loathsome , 

 appearance. In such cases the eye is totally destroyed. 



Treatment. — This must consist in the free use of the knife, 

 and in the early stage they may be completely removed; 

 every particle must be caref uUy cut away, and the parts after- 

 wards dressed with a mild caustic. When very large and 

 involving the eyeball, it is necessary to remove the whole 

 orbit.
