28o Management and Treatment of the Horse. 



ficial aid is necessary to enable it to perform its 

 office. If the theory of Mr. Clark was correct, 

 what would supply the place of those parasites 

 during the time of year that the grub assumed 

 its perfect condition ? In post-mortem examin- 

 ations I have made, proof has not been wanting 

 of their not being inoffensive, as Mr. Bracy Clark 

 supposed. One subject I opened four years ago — 

 a black cart mare, the property of Frederick 

 IS'eame, Esq., of Macknade House, Favershara, 

 which died from violent inflammation, and the 

 stomach, upon opening it, was found covered with 

 these parasites. So thick were they that you 

 could not see one particle of the mucous mem- 

 brane of the stomach, they forming a complete 

 lining. Upon removing the parasites, the mucous 

 membrane was eaten into holes, in some places 

 nearly through the substance of the stomach. 

 They were also found through the entire intes- 

 tines so numerous as to leave no doubt that they 

 were the primary cause of the animal's death, and 

 although they were so numerous in the animal, 

 no one suspected their existence, as none had 

 been seen in the evacuations. The progress of 

 this disease generally manifests itself slowly ; the 

 horse becomes hide-bound, its coat becomes 

 rough and unhealthy, it loses flesh and strength, 

 although it feeds with its usual appetite, and 

 frequently it has a short tickling cough. The 

 bot, as I have said before, is a species of the gad- 

 fly, which may be observed in the months of July, 

 flying actively about the legs of horses in the 

 fields, or sticking fast to their ribs when ridden 

 along a road. These are the females depositing
