244 INORGANIC AGENTS 



Properties, — Irregular pieces of a liver-brown color,, 

 which by exposure to the air gradually absorb moisture, 

 oxygen, and carbonic dioxide, and change to greenish-yellow 

 and finally to a gray mass containing potassium carbonate, 

 hyposulphite and sulphate. The compound has a faint odor 

 of hydrogen sulphide, and a bitter alkaline taste. Soluble 

 in 2 parts of water, with the exception of a small residue. 



Dose.—B.. k C, 3 ii.-iv. (8.-15.); D., gr.ii.-x. (.12-.6). 



Action Inte7'nal. — Sulphurated potassa has practically 

 the same action as sulphur, internally and externally, 

 although more stimulating locally. Large doses have caused 

 gastro-intestinal inflammation, and the remote effects ob- 

 served after repeated enormous doses of sulphur : i. e., dis- 

 organization of the blood and paralysis of nerves and 

 muscles. It has been administered internally as a substi- 

 tute for sulphur, but is only of value externally. 



Action and Uses External. — Sulphurated potassa is one 

 of the most serviceable agents we possess in the treatment 

 of chronic forms of skin diseases, as psoriasis, lichen, but 

 particularly eczema of the horse and dog. It is locally 

 stimulant, alterative (?), and parasiticide. There is only one 

 drawback to its general use, which is its exceedingly dis- 

 agreeable odor. Peruvian Vjalsam is frequently substituted 

 for this reason in the treatment of skin diseases in dogs. A 

 solution, "yellow lotion," is used in different strengths (1-8 

 to 1-15), according to the amount of stimulation which the 

 skin will endure. The "yellow lotion," is a good agent for 

 killing lice upon the skin. The following prescription will 

 be found of benefit in canine practice.
