etc. Inflammation and partial or total clogging- of the organ 

 resnlt. Cantharides will reach the kidnej's after absorption 

 from a large blistered surface. 



Si/)nptoms. — The most important and often the only mani- 

 festations of nephritis (in the course of infectious diseases, for 

 instance) are furnished by the urine. Its quantity is dimin- 

 ished ; it is thickened ; of abnormal color ; occasionally it is the 

 color of blood. Micturation (pissing) is painful; the urine 

 often runs otf drop by drop only, notwithstanding the violent 

 efforts made by the patient. In serious cases the urinary secre- 

 tion may be completely suppressed. 



The lumbar region is very sensitive to the pressure of the 

 hand. At the beginning of the disease we often have renal or 

 kidney colics. The back is arched, the gait stiff and stagger- 

 ing, rising is painful; the animal remains almost constant^ 

 standing. The appetite may be lost. The temperature is ele- 

 vated; in some cases it may range very high. 



Treat})! ent. — Eemove the cause if possible; avoid all irrita- 

 ting food or medicines, and give absolute rest. Try to induce 

 sweating by energetic rubbings upon the surface of the whole 

 bod}'; also hj warm blankets, and wet, tepid compresses ap- 

 plied upon the loins. Give the following physic: Aloes 6 

 drams, calomel 1 dram, ginger 1 dram. Make into a ball and 

 give at one dose. It has a most favorable action, because the 

 purging draws a large quantity of water from the system. 



If there is a total suppression of urine, | ounce of fluid 

 extract digitalis, well rubbed in on each side of the loins over 

 the kidne^-s, will have a beneficial effect by stimulating the 

 kidneys without causing irritation. This application should 

 not be used more than once. 



DIABETES INSIPIDUS SIMPLE DIABETES (pISSIXG).

 twenty-four hours; great thirst, the animal sometimes drink- 

 ing from 20 to 25 gallons of water in twenty-four hours; de- 

 praved appetite; urine of a very pale color, sometimes as clear
