The marsh gas varied from 16 to 39 per cent., being especially- 

 abundant in cases of abstinence. It should, therefore, be in large 

 amount in the tympanies which accompany febrile and other 

 chronic affections. Hydrogen sulphide was found only in traces, 

 recognizable by blackening paper saturated with acetate of lead. 



Oxygen and nitrogen were in small amount and were attributed 

 to air swallowed with the food. In the work of fermentation the 

 oxygen may be entirely used up. 



Lesions. These are in the main the result of compression of 

 the different organs, by the overdistended rumen. Rupture of the 

 rumen is frequent. The abdominal organs are generally blood- 

 less, the liver and spleen shrunken and pale, though sometimes 

 the seat of congestion or even hemorrhage. Ecchymoses are 

 common on the peritoneum. The right heart and lungs are 

 gorged with black blood, clotted loosely, and reddening on 

 exposure. The right auricle has been found ruptured. Pleura, 

 pericardium and endocardium are ecchymotic. The capillary 

 system of the skin, and of the brain and its membranes, is 

 engorged, with, in some instances, serous extravasations. 



Prevention. This would demand the avoidance or correction 

 of all those conditions which contribute to tympany. In fevers 

 and extensive inflammations, when rumination is suspended, the 

 diet should be restricted in quantity and of materials that are
