330 DISEASES OF CATTLE. 



bowl or basin, containing one ounce eacb of common salt 

 and oxide of manganese, and pour over this a mixture, 

 say, water, half an ounce; sulphuric acid, one ounce and 

 a half; stir with a stick, and chlorine gas will be evolved. 

 When sufficiently stirred, leave the place, and close the 

 door. Repeat the inhalations for two or three times, 

 and let two days pass before each subsequent inhalation. 

 If the animal be much weakened by the parasites, mix 

 carraway and fenugreek in their feed, of each a quarter 

 of an ounce, once a day for a week or so. 



Hoven. — Tympanitis or Brum-helli/. — So called from 

 the appearance and sound. This disease is the evolution, 

 or giving off of carbonic acid gas, from the large quantity 

 of grass or clover when wet, contained within the rumen 

 or paunch, together with the suspension of the function 

 of digestion, and peristaltic action of the bowels, all of 

 which combined, go to make up the disease called hoven. 

 Hoven may occur in one hour, for we often see 

 cows turned out to pasture in the morning, and are al- 

 most found suffocated in an hour afterward. There is 

 obviously no time to be here lost. Every farmer should 

 always be prepared to meet and cure such cases as they 

 occur, as there is no time to run for assistance. 



Cause. — Over filling the paunch, and in too quick a 

 time, before the stomach has time to act upon it; and 

 hence fermentation is set up. 



Symptoms. — Great distress; the sides are distended, 

 and when struck, sound like a drum, the beast lying and 

 rising ; the breathing is hurried ; there is great suffering, 

 and if not speedily relieved, the rumen will give way, 

 burst or rupture; if this does not happen shortly, the 

 brain becomes affected, and the beast dies unconscious. 

 The disease runs its course with fearful rapidity.
