sui generis which, hke the worms in the human body, 

 forms a part of the animal economy ? 



Should the worm ever prove troublesome to the ani- 

 mal, it niii<ht probably be distinguished by its motions 

 and the discharge from its nose, and relief I think, might 

 be afforded by trepanning the exterior bone over the 

 frontal sinuses, in which the worms are chiefly found, 

 about an inch above the socket of the eye, and either 

 drawing them forth with a pair of tweezers, or blowing 

 the smoke of sulphur on them, which would probably 

 drive them down the nostril, whence they might be 

 blown out by the sneezing of the animal, produced by 

 the fumes of the sulphur. The bone over the frontal 

 cavity is very thin, and there is nothing of vital impor- 

 tance intervening to render the operation difficult or dan- 

 gerous. 



11. Prolapsus Vaginae, — This disease seldom, if ever 

 occurs except in advanced stages of pregnancy, and is 

 then oftentimes very troublesome. I have had many 

 cases in my flock, but only the first terminated fatally. 

 In this the inflammation was so excessive, as to render a 

 permanent reduction impracticable : finding therefore that 

 the destruction of both the mother and foetus would be 

 the inevitable consequence unless speedily relieved, I 

 had recourse to the only remaining alternation ; the caesa- 

 rean operation, which was successfully performed. After 

 going through the regular process of killing the ewe, the 

 lamb was preserved and raised, even though ushered into 

 the world, to all appearance a week before its time. 



This affection is generally I think to be ascribed to too 

 much blood, but it is oftentimes brought on by the ewes 

 rearing up against the rack in order to feed over the top, 

 which should by all means be prevented. The vagina 

 may generally be reduced by raising the animal up by
