easily digested (well boiled gruels, bran mashes, pulped roots, 

 etc. . ) and all bulky, fibrous and fermentescible articles must be 

 proscribed. In weak conditions in which tympany supervenes 

 on every meal, a careful diet may be supplemented by a course of 

 tonics, carminatives and antiseptics such as fceungrec, oxide of 

 iron, hyposulphite of soda and common salt, equal parts, nux 

 vomica 2 drs. to every 1 lb. of the mixture. Dose 1 oz. daily in 

 the food, or J^ oz. may be given with each meal. 



Musty grain and fodder should be carefully avoided, also 

 mowburnt hay, an excess of green food to which the stock is un- 

 accustomed, clover after a moderate shower, or covered with dew 

 or hoarfrost, frosted beet, turnip, or potato tops, frosted potatoes, 

 turnips or apples, also ryegrass, millet, corn, vetches, peas with 

 the seeds fairly matured but not yet fully hardened. When 

 these conditions cannot be altogether avoided, the objectionable 

 ration should be allowed only in small amount at one time and in 

 the case of pasturage the stock should have a fair allowance of 

 grain or other dry feed just before they are turned out. Another 

 precaution is to keep the stock constantly in motion so that they 

 can only take in slowly and in small quantity the wet or other- 

 wise dangerous aliment. 



When it becomes necessary to make an extreme transition 

 from one ration to another, and especially from dry to green 

 food, measures should be taken to make the change slowly, by 

 giving the new food in small quantities at intervals, while the 

 major portion of the diet remains as before, until the faeces indi- 

 cate that the superadded aliment has passed through the aliment- 

 ary canal. Another method is to mix the dry and green aliments 

 with a daily increasing allowance of the latter. Some have 

 avoided the morning dew and danger of fermentation by cutting 

 the ration for each succeeding day the previous afternoon and 

 keeping it in the interval under cover. 



Treatment. Various simple mechanical resorts are often effect- 

 ive in dispelling the tympany. Walking the animal around will 

 sometimes lead to relaxation of the tension of the walls of the 

 demicanal and even to some restoration of the movements of the 

 rumen with more or less free eructation of gas. The dashing of 

 a bucket of cold water on the left side of the abdomen some- 

 times produces a similar result. Active rubbing or even knead-
