tion, and even leads to inflammation of the kidneys. The 

 usual symptoms consist in discharge of urine which is at 

 first rather dark coloured, reddish, transparent, and after- 

 wards bloody. The quantity of urine is usually scanty, and 

 it is emitted with pain. The symptoms of a slight renal in- 

 flammation appear, such as stiff gait, sensibility of the loins, 

 staring coat, fever, loss of appetite, suspended secretion of 

 milk, &c. The symptoms of irritative fever and renal in- 

 flammation may be severe, and the animals die. In some 

 cases abscesses form in the kidneys. The disease lasts from 

 one to three weeks. 



This disease is essentially enzootic. It occurs principally 

 in the spring, and when, with great heat, there is a scarcity 

 of water. It is due principally to the astringent principle of 

 plants and young trees which animals eat. In France the 

 malady is due in extensive tracts of land, to genista hispanica, 

 and is hence termed " genestade." Mercurialis annua and 

 perrennis have been noticed to induce the disease by Jungin- 

 ger, Dubois, Schack, and Hering. Kuers has found it due 

 to polygonum hydropiper, when the malady occurs late in the 

 season. Hiibner has traced the malady to be due occasion- 

 ally to arnica montana, and Schneider to aconitum gracile, 

 which induces discharge of blood with the milk as well as 

 with the urine. In Holland, enzootic hsematuria has been 

 attributed to aconite, digitalis, ranunculacese, and especially 

 pedicularis palustris. Weinmann has found it due to pyrola 

 rotundifolia. 



The treatment of this disease consists in removing the 

 animals from the pastures where they have suffered, ad- 

 ministering a full dose of a saline purgative, and following 

 this up by large doses of linseed tea. When the amount of 

 depression is great, camphor and ammonia should be given 

 in gruel or linseed tea. If the discharge by the kidneys is
