DISEASES OF SHEEP. 



quite incurable. I can only describe it as a soft, 

 spongy tumour, rising- from the bottom of the eye, 

 involving all the textures of that organ, so as to render 

 them scarcely recognizable, and bleeding on the slight- 

 est touch. It is readily removed by passing a stout 

 thread through the front of the eye with a needle, so 

 as to aflPord the operator a hold by which to pull it 

 outwards with the left hand, while, with the right, he 

 cuts round it with a narrow-bladed knife. The opera- 

 tion is attended only with slight pain, but must not be 

 considered the sole curative means ; the sheep must 

 have, at the same time, a frequent change of pasture, 

 to prevent a recurrence of the tumour. 



There is a very large tumour of this description at 

 present in the museum of Guy*s Hospital, taken from 

 a »heep which recovered perfectly.
