fal. Copious injections of warm soapy water are given 

 soon after. Two-ounce doses of carbonate of ammonia 

 follow the purgative at intervals of three hours, with 

 abundance of thin linseed gruel. If the later stages 

 occur, thirty grains of nux vomica should be given and 

 relocated every half hour and the injections continued. 

 When the animal becomes violent it should be secured 

 where it can do no harm, and if need be, sheaves of straw 

 should be so disposed as to protect it from injury. On 

 recovery the feeding .should be gradually restored and a 

 course of tonics followed for two or three weeks. Bran 

 and linseed meal mashes with gentian and ginger will be 

 found useful. 



TUBERCULOSIS. 



The best bred and fed cows are subject to an insidious 

 but most serious disorder which becomes constitutional, 

 and is contagious under certain favoring conditions and 

 disposition of the exposed animals. This disease con-

 changes to a soft, yellowish cheesy mass. These cells 

 rupture and discharge this soft matter, leaving cavities 

 of considerable size, which sometimes destroy the greater 

 part of some important organ, as the lungs, liver, spleen, 

 kidneys, etc. • This disease is communicated by inocu- 

 lation and by eating the diseased meat, or the milk, if 

 the udder is diseased ; but it is more often produced as 

 the result of some local inflammation which seems to

 is abundantly scattered in the atmosphere waiting to find 

 a resting place where it may serve its destructive°purpose 

 in nature.
