Uses: Externally for enlarged glands, periosteal inflammation, 

 capped hock, curb, chronic synovitis, pharyngitis, and laryngitis; 

 to stimulate granulations in slow-healing wounds and promote the 

 growth of hair. Useful to disinfect the skin before operations; 

 as a parasiticide in mange, ringworm, and f avus ; iodoform is used 

 as a dusting powder in suppurative wounds for its bactericidal and 

 stimulating effect. It also has a slight anaesthetic action.

 specific in actinomycosis ; alterative in chronic bronchitis and laryn- 

 gitis; antidote for chronic lead poisoning; goitre, scirrhous cord, 

 botryomycosis, hydrothorax, ascites, cirrhosis of the liver, and 

 periodic ophthalmia are often improved by the use of potassium

 of resolution in pneumonia. 



What effect has acetanilide on the temperature? Give its action and 

 uses. 

 Acetanilide has a decided antipyretic effect in fevers, but little 

 effect on a normal temperature. It is mildly diaphoretic, slightly 

 antiseptic, diuretic, and depressant to the heart. 



It should be used in very high fevers only, especially thermic 

 fever (sunstroke), in one- to two-drachm doses, repeated not oftener 

 than every six hours. 



State the source and the uses of acetanilide. 



Acetanilide is obtained by distilling together glacial acetic acid 

 and anUine and purifying the residue by repeated crystallization. 

 (See answer to preceding question.)
