318 GOEGED STOMACH.— TTMPAin:. 



The abdomen is hard and tense ; the respirations are short, 

 catching, and frequently gasping ; the pulse at the commence- 

 ment is seldom disturbed ; the skin speedily becomes bathed 

 with perspiration, which is sometimes cold, and at other times 

 hot and steaming. As the violence of the pain subsides, rum- 

 bling sounds will be heard to proceed from the abdomen, which 

 are occasionally relieved by an abundant emission of flatus. 



Pathogis^omonic Symptoms. — Excessive or partial disten-

 beans, or a quantity of dry bean flour eaten immediately after 

 severe and long continued labour. 



Crib-biting horses are said to be more prone to Tympany 

 than others ; but this I am unable to verify from experience. 

 Wheat, both in its ripe and green condition, will cause it, and 

 in all probability the death of the animal as well. Several of 

 the most severe attacks of Tympany I have ever observed, 

 arose from the animals having partaken freely of green wheat. 

 Mr. Percival mentions that during " the march of the British 

 Army from "Waterloo to Paris, in 1815, a brigade of horses had 

 been allowed to f^ed in a field of growing wheat, and the con- 

 sequences were, that several of them became tympanitic in the 

 body, and became almost frantic with pain and died," Mr. Per- 

 cival and others who have written upon this form of disease 

 consider that the gas originates from a species of fermenta- 

 tion set up within the food ; but this I believe to be an
