APPENDIX. STOMACH STAGGERS. 361 



The Stomach, with its contents, of one horse 

 that died of this complaint, weighed nearly 

 sixty lbs. Its coats were so stretched that they 

 were easily torn, and had, no doubt, lost all 

 power of contracting. Some time before 

 death, the food which it contained was ratiier 

 hard, consisting of imperfectly masticated 

 hay and oats. The 3'ellowne.^s observable in 

 the horse's eyes and mouth a])])eared to have 

 been occasioned by the pressure of the sto- 

 mach upon the gall duct, causir:g the bile to 

 return into the circulation. A considerable 

 number of liorses that died of this disease 

 was examined, and the same appearance cb- 

 sei*ved in all of them : we therefore concluded 

 the immediate cause of this kind of stagroerfs 

 was an accumulation of indio-estible food ik 

 the stomach: but as the disease also happened 

 to horses at grass, and in two or three cases 

 even to such as had been at grass some time 

 without being changed into other grass, it" 

 became necessary to inquire into the cause 

 of this accumulation. In many cases, where 

 it attacked horses kept in stables, it was 

 ascertained without difficulty. The horses 

 most liable to it were such as had been muck 

 exhausted by hard work, unwholesome food,
