MATERIA MEDICA AND THERAPEUTICS IO3 



The sulphurous acid is used in foot and mouth diseases, as a 

 spray or on lint; in diphtheria and in epizootic aphthae, etc., as a 

 spray ; used internally in septicaemia and flatulence. 



Antagonists and Incompatibles of Sulphur, Sulphides and 

 Sulphites. — The mineral acids, including sulphuric, decompose 

 the sulphites and hyposulphites. All oxidizing agents are in- 

 compatible, as these preparations have a great affinity for oxygen 

 and the sulphites readily become sulphates. Solutions of the 

 metals are incompatible with sulphides of potash and calcium. 



Antidotes.— Are chlorine water, common salt, sulphate of 

 iron, etc. 



Synergist. — All agents which arrest fermentative processes 

 or promote waste. The alkalies favor their action, both chemi- 

 cally and physiologically. 



IODINE AND ITS PREPARATIONS. 



IODUM — Iodine. — Occurs in bluish black crystalline scales 

 of a metalic lustre, slightly soluble in water, i in 5000, alcohol, 1 

 in 10, ether, 1 in 4, and in a solution of iodide of potash and a 

 solution of chloride of sodium, is very soluble. It is non-me- 

 tallic. It is obtained from the ashes of sea-weeds and should be 

 kept in glass stoppered bottles in a cool place. We use the Re- 

 sublimed Iodine. Dose of the resublimed for horse, 15 grs. to 

 1 dr. ; cattle the same ; sheep, 10 to 30 grs. ; pigs, 5 to 20 grs. ; 

 dogs, y 4 to 1 gr. 



LIQUOR IODI COMPOSITUS— Compound solution of^ 

 iodine, 



Synonym. — Lugols Solution, Iodine 5 parts, potassium iodide 

 10 parts, distilled water qs. to make 100 parts. It is always well 

 to make your own solutions of any strength you desire. Horses 

 and cattle y 2 to 1 oz. 



AMMONII IODIDUM— AMMONIUM IODIDE— Iodide 

 of Ammonia. — White granular, very deliquescent salt, becoming 

 yellowish brown by exposure, very soluble in water and alcohol. 



Dose. — Horse, 1 to 4 drs. average dose 2 drs. ; dogs, 1 to 10 

 grs. Very good in pneumonia where resolution is tardy. 



SODII IODIDUM— SODIUM IODIDE— Iodide of Soda. 

 — Minute crystals or crystalline powder, deliquescent, having a
