From examinations of samples of urine, and fi-om the history 

 of cases kindly furnished by numerous veterinarians, as well 

 as from what has more immediately come under my notice, I 

 am induced to conclude that the disease originates in an im- 

 poverished condition of the blood, arising from want of proper 

 food ; that the albumen of the blood is thus degraded in quality, 

 and as such is unfit to be appropriated for the nourishment of 

 the tissues, and is consequently excreted by the kidneys and 

 expelled from the l)ody ; that the blood globules are in a 

 broken-down or disintegrated condition, arising from solution of 

 their outer layers or cell walls, when their coloured interior — 

 haematiu — escapes, wliich, mixing with the serum of the blood, 

 and being eliminated by tlie kidneys, gives the characteristic 

 tinge to the urinary secretion. This mal-condition of tlie 

 blood is succeeded by diseases of various organs ; most notably 

 congestion of the liver ; irritation of the intestinal mucous 

 membrane, as expressed by diarrhoea ; paralysis of the intestinal 

 canal, giving origin to an apparent constipation, and in some 

 instances to severe cerebral disturbance, manifested by delirium 

 and convulsions. The irregularity of the heart's action, as M^ell 

 as the feebleness and peculiar trembling or thrilling of the pulse.
