lining membrane of fistulas of the poll, withers, or lateral cartilages; to 

 swab out a septic uterus, and as a local anassthetic upon the skin. To 

 destroy fistul» the pure phenol is injected and, after two minutes, the 

 fistula is washed out with alcohol. A drop of pure acid, or a line drawn 

 with a brush along a proposed path of incision, may render a hypoder^ 

 mic puncture or superficial incision painless. Carbolic acid with glycer- 

 in (1-16) is one of the most excellent preparations for applying to 

 sluggish ulcers and old sinuses and fistulas. The glycerin appears to 

 entirely offset the corrosive action of the acid, and the result is a stimu- 

 lation of the pyogenic membrane and promotion of healing which often 

 can not be obtained by any other remedy. It is equally effective in 

 canker and foul in the foot of cattle, and in foot rot of sheep (1 part 

 in 10 of glycerin). Injection of ten to thirty drops of a two per cent. 

 aqueous solution into the substance of boils, acne, glandular swellings, 

 poisoned wounds, joints affected with chronic synovitis, and inflamed bur- 

 sas, will often assist recovery and may abort the lesion. In the two last, 

 TTLx-xxx. of the pure acid. 



In acute inflammation, the injections are made twice daily; in 

 chronic conditions, once every other day; and if there is a large extent 

 of surface involved, several injections are done at one time. 



Erysipelatous patches are best treated by swabbing them with pure 

 phenol followed at once by swabbing with pure alcohol. This is done 

 not only to the patch itself but the surrounding normal area should be 

 somewhat encroached upon. 



Wet dressings, made by saturating aseptic gauze in 1^ to 1 per 

 cent, solutions of phenol and applied with a rubber cloth or oil paper 

 or silk covering, have been much used in surgery in the treatment of 

 septic wounds. Many cases of local gangrene have been reported in 

 human surgery following such application to the extremities. It is 

 safer and just as effective to use a 1 per cent, lysol (liq. cresolis co.) 

 solution for an antiseptic wet dressing. 



Bacelli's treatment of tetanus with carbolic acid is said to be suc- 

 cessful. One dram of the pure acid in solution (3 per cent.) should be 

 injected subcutaneously in the region of the neck and shoulders of the 

 horse every two hours during the first 32 hours, and less frequently 

 afterward. As much as 36 drams may be given to the horse in 24 hours, 

 for there appears to be a special tolerance for carbolic acid acquired 

 in tetanus. The writer has found the solution too bulky to be used in 

 practice and its remedial effect is doubtful. Magnesium sulphate is 

 much more efficient. 



The glycerite 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 purpose. Two per cent, solutions are recom- 

 mended 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 unbroken skin, but the strength 

 should not be greater than half this amount upon excoriated surfaces.
