TYMPANITES. 441 



he ruptured ; rupture of the rumen is, however, very un- 

 common. In the latter stages, brain symptoms are pre- 

 sented. The eyes protrude and are reddened in appearance. 

 The tongue also is allowed to protrude from the mouth. 

 The animal becomes excitable, and then delirious, falls or 

 lies down, and dies within a few minutes. 



Treatment — The treatment of hoven should be pronijDt 

 and energetic. Those remedies which unite chemically 

 with and destroy the gases generated, and prevent the 

 further generation of gases, should be employed. Ammon. 

 carb. 5SS. — 5i. in water will very frequently have the desired 

 effect. The following draught is also of great service in 

 many cases: ol. terebinth ji. — siv., ol. lini. Jviii — 3xvi., and 

 follow with magnesia sulphat. lb. i. — lb. ij., aqua q. s. to 

 dissolve. Chlorinated lime, potassae chlorat., etc., are all of 

 great excellence ; but the oleaginous draught above men- 

 tioned is preferable to all others. If the animal be 

 seriously swollen, and it becomes evident that unless relieved 

 death will occur before the medicines given can take effect, 

 the condition must be relieved by passing the hollow pro- 

 bang into the rumen and allowing the gas to escape through 

 it. Or what is still better, by using the trocar and canula 

 to puncture the rumen, after which the trocar should be 

 withdrawn, and the canula allowed to remain until all the 

 gas has escaped and the abdomen returned to its normal 

 proportions. The operation should not be too long deferred, 

 but should be performed while the animal has plenty of 

 vitality. What is usually sold by instrument dealers as a 

 cattle trocar is objectionable on account of its size, the 

 ordinary horse trocar being preferable. The hollow pro- 

 bang is also good in cases where there is no great amount 

 of ingesta in the rumen. After getting rid of the tympanitic 

 condition a full dose of cathartic medicine should be ad- 

 ministered, in combination with stimulants, as ammonia,
