IN ANTISEPTIC SURGERY 569 



In horses, as in human patients, a few, frequently repeated 

 doses arrest attacks of acute nasal catarrh when given in 

 the earlier stages, and appear to have a similar power in 

 gastro-intestinal and urinary catarrh. Frohner recommends 

 it in cystitis. Kobertson used it in equine influenza accom- 

 panied with gastro-intestinal symptoms. Other practi- 

 tioners testify to its value in purpura and also in strangles. 

 In zymotic and malarial fevers it is not so effectual as 

 quinine. Feser has shown that it exerts no antipyretic 

 effect in septic or pyaemic fever. Conjoined with tannic 

 acid it is prescribed for obstinate diarrhoea in calves. 



In antiseptic surgery, salicylic acid is sometimes substi- 

 tuted for or alternated with carbolic acid or creolin. It is 

 serviceable in the treatment of canker and open joint, for 

 abating the itching and discharge of eczema, for dressing 

 sores on the teats of cows, washing out the uterus in metritis, 

 and with alcohol as an injection in otorrhcea. Its anti- 

 septic effects are increased by admixture of boracic acid. 



DOSES, etc. Horses and cattle take ^iv. to i. ; sheep 

 and goats, 3J- to 3 n 'j. ; swine, grs. xlv. to grs. Ixx. ; dogs, 

 grs. v. to grs. xxx. of sodium salicylate, administered with 

 mucilage or glycerin, in bolus, electuary, or drench. Sali- 

 cylic acid and salicin are used in similar amounts. The 

 larger doses are given in fevers ; the smaller, repeated 

 frequently, in rheumatism, in the muscular form of which 

 a solution may be injected deeply into the affected part. 



For surgical purposes convenient solutions are made by 

 dissolving one part each of salicylic acid and borax in 

 thirty to fifty parts of water. Ointments and liniments are 

 prepared with one part acid, mixed in a heated mortar, 

 with twenty to twenty-five of vaseline or bland oil. Sali- 

 cylic collodion, for protecting small wounds, consists of 

 salicylic acid one part and flexible collodion nine parts. 

 Salicylic cream, employed as a pigment for surgical wounds, 

 is composed of two parts salicylic acid, and ten parts of 

 glycerin. The B.P. ointment consists of one part acid, 

 and forty-nine parts of white paraffin ointment. Lint, 

 cotton-wool, or jute, soaked in 4 to 10 per cent, hot, watery 

 solution, made with borax to ensure solubility, absorbs the 

 acid, and is used as an antiseptic covering for wounds and
