154 VOMITING. 



But veterinary surgeons are well aware that in acute cases 

 of vomiting, in cases of stomach staggers, the stomach has 

 already given way, and by this the mucous membrane form- 

 ing hernia, through the laceration, any obstruction at the 

 cardiac orifice is overcome. The close manner in which the 

 organs are applied to each other in the abdomen explains how, 

 with an inert and, indeed, torn stomach, by the action of 

 the abdominal walls, ejection readily occurs. Those who may 

 be incredulous that, after the walls of the stomach having 

 given way, there could be any vomiting, may be reminded of 

 a case referred to by Longet, in which a woman, having swal- 

 lowed sulphuric acid, suffered from violent vomiting up to 

 the time of her death, after which it was found that the walls 

 of the cavity had been completely destroyed. 



with spume generally, and some of the smaller ramifications contained 

 similar dark fluid to that ejected. The lining membrane of the bron- 

 chial tubes was inflamed. The heart was perfectly natural : no staining 

 of arterial or venous tubes. 



" The abdomen presented distention of the stomach, which was very 

 large, and contained fluid of the same kind as that retched up : also, 

 some fragments of half-digested hay, part of a ball with its paper 

 envelope, some bots which were adherent both to the cuticular and to 

 the villous coats, and several irregular elevated spots of ecchymosis 

 beneath the villous coat, particularly contiguous to the cuticular coat, v 

 which must have been effused during the great contractile effort of the 

 stomach : internally, this viscus was not inflamed, but externally it was 

 discoloured. The duodenum was also distended for eighteen inches of 

 its length, and then suffered contraction, as if tied with a band, about 

 an inch and a half broad. On opening the intestine it was extremely 

 inflamed, almost approaching to gangrene, just anterior to the pallid 

 and compressed portion. The other intestines were healthy. The 

 liver was much gorged, and the hepatic duct and branches were dis- 

 tended with bile, which flowed out freely when the duct was divided. 



" Thus we have another condition inducing vomiting in the horse. 

 Although I have seen hernia of the foramen of Winslow, vomiting did 

 not accompany it."
