ALTERATIVES. 75 



Chronic and capillar}- bronchitis — ammonium iodide, 

 in small, frequently repeated doses. Catarrhal pneu- 

 monia — ammonium iodide and arsenic, to prevent 

 caseation of the inflammatory products. They may 

 be used to promote absorption of waste products, as 

 in lymphangitis, pleuritic or other serous effusions, 

 enlarged glands, duodenal catarrh, bronchitis, pneu- 

 monia, chronic cough, actinomycosis in cattle, pur- 

 pura hemorrhagica, rheumatic affections (with col- 

 chicum), chronic lead and mercurial poisoning. 



Therapeutics of Iodoform and Iodol. — 

 Chronic gastric and intestinal catarrh — iodol between 

 feeding-times. Bronchitis and bronchial catarrh — 

 iodol and senega. To foul wounds, ulcers, sores, etc. 

 — iodoform ; also made into suitable suppositories and 

 introduced into fistulse, the rectum, and genito-urin- 

 ary organs as antiseptics. To open joints, one of the 

 best applications is equal parts of iodoform and pow- 

 dered alum. Diabetes insipidus has been successfully 

 treated with both iodoform and iodol — preferably the 

 latter. 



Hydrargyrum — Mercury. 



Symbol, Hg; atomic weight, 200; quantivalence, 

 2 and 4 ; sometimes called " quicksilver " because of 

 its extreme motility and metallic lustre. It is the 

 only known liquid element, and its most common 

 source is as a sulphide, from which it is obtained by 

 heat to drive off the sulphur and Hg distils over. 



Hydrargyri Chloridum Corrosivum (HgCL). — 

 Corrosive chloride of mercury, mercuric chloride.
