 blood, which they have thus liberated, giving to it the red colour noted, 

 and instituting the name of the disease.

 was determined from a sample taken from a recent case I had : —

 water is generally seen standing by itself in the field, with nose extended,

 m.ilkers, the secretion is suspended ; the nose, eyes, mouth, udder, and 

 vagina have a dirty yellow cast, while the lips of the vulva have a 

 tight, puckeredup appearance, and the urine has, as already stated,

 the disease advances, all the symptoms become aggravated, but an 

 obstinate constipation takes the place of the diarrhoea. In my opinion, 

 this suspension of the action of the stomach and bowels is due to the 

 deteriorated blood acting on the nerve centres, causing perverted

 alimentary tract ; and the poor brute's condition becomes much more
