312 INORGANIC AGENTS 



Bacelli's treatment of tetanus with carbolic acid lias 

 met with considerable success of late. One drachm of the 

 pure acid in solution (5 to 10 per cent) should be injected in 

 the region of the neck and shoulders of the horse every two 

 hours during the first 32 hours, and less frequently after- 

 ward. As much as 36 drachms may be given to the horse 

 in 24 hours, for there appears to be a special tolerance 

 for carbolic acid acquired in tetanus. 



Instruments are frequently placed in carbolic acid 

 solution (1-40) during surgical operations, although it is 

 sufficient to boil them in water for ten minutes and keep 

 them in the boiled water, or place them in a pure atmos- 

 phere upon boiled towels. Carbolized gauze is prepared 

 from unbleached cotton gauze medicated with half its 

 weight of a mixture consisting of carbolic acid, 1 ; resin, 3 ; 

 and paraffin, 4 parts. Plain gauze, sterilized by baking at a 

 temperature of 140° C. for* two hours, is preferable, and 

 avoids the danger of absorption and poisoning. The gly- 

 cerite of carbolic acid is employed as a local application in 

 stomatitis, upon the ulcerations of actinomycosis with 

 iodine, and also upon the skin to destroy ringworm. It is 

 inferior, however, to tincture of iodine for the latter pur- 

 pose. Two per cent, solutions are recommended to kill 

 lice and the acari of scab and mange. Carbolic acid is the 

 most serviceable remedy we possess to relieve itching. 

 Two per cent, .solutions may be employed upon the un- 

 broken skin, but the strength should not be greater than 

 half this amount upon excoriated surfaces. In sub-acute 

 moist eczema of dogs, carbolic acid with zinc ointment 

 (gr.5- 5 i.), or the following prescription, will be found of 

 value in relieving itching and promoting recovery :
