210 THE NATURE AND TREATMENT OP 



Mix the ingredients in the above order. Give one-eighth 

 of the above quantity twice daily. Friction on the external 

 surface with a good stiff brush, will prove also beneficial. 



If the darkened color of the urine is owing to functional 

 derangement of the liver, which may be known by the brown 

 and yellow color of the membranes of the mouth, I should use 

 the following : — 



Powdered Podophyllum, 1 ounce. 



" Hyposulphite of Soda, 2 ounces. 



Mix, and divide the mass into six parts ; give one, night and 

 morning, in a pint of water. Grass, if it can be obtained, is 

 the best food for such a patient. 



RED WATER. 



The changes which occur in the color of urine are the results 

 of various causes. In a preceeding article the reader is in- 

 formed that haematuria, — voiding of blood with urine, — is 

 traceable to certain direct causes, hence the difficulty is of an 

 acute character. 



Now suppose we take a well animal as a subject for exper- 

 iment ; we administer repeated doses of sweet spirits of nitre, 

 or tincture of juniper ; the first thing we notice is, the urine is 

 augmented, or rather more profuse than usual, and of a pale 

 color ; continue the medicaments over a given period and the 

 urine assumes a darker color, first yellow, next brown or coffee 

 color, purple, or even black ; this shows conclusively that the 

 color of the urine can be altered by the use of medicinal 

 agents ; therefore, if a reddened appearance of the urine fol- 

 low the exhibition of strong diuretics, the cause is plain 

 enough and the cure is effected by discontinuing the diuretic 

 medicine, and in restoring the equilibrium of action which 

 should exist among the various excretory organs. Various 

 kinds of food are also operative in producing changes in the 

 color and quantity of the urinary secretion ; beets and carrots 

 when " fed " in quantity for a sufficient length of time, alter 

 essentially, the color of the fluids of the body, urine included.
