controlled by cross tying or tying the head up short to prevent him 

 from biting, rubbing, or lying on the blistered area. The tail must 

 be tied up if within reach of the blister. The blister should be left 

 on for 24 hours and then washed off and the parts kept clean and well 

 oiled to prevent cracking of the skin. Blisters should not be applied 

 to the back of joints or to any acutely inflamed parts.

MEDICINES. 



283. Acetanilid. Antiseptic. Used externally as a dusting 

 powder, alone or in combination with other drugs. 



284. Acid, arsenious (arsenic). Irritant, caustic poison. 

 It is sometimes given as a tonic in the form of Fowler's solution 

 in J to 1 ounce doses. 



285. Acid, boracic (boric acid). Nonirritant antiseptic. Used 

 in all strengths up to a saturated solution as a mild soothing anti- 

 septic in diseases of the eyes, and as a wet or dry dressing for wounds. 

 Also in the form of an ointment for burns, etc., strength 10 per cent. 

 Used alone or in combination with other drugs. 



286. Acid, carbolic (phenol). A caustic, disinfectant, and anti- 

 septic. Pure carbolic occurs in crystals which may be dissolved 

 by heat and the addition of glycerin, alcohol, or water. Carbolic 

 acid is a powerful poison and is readily absorbed from raw surfaces, 

 hence must not be used too freely in strong solutions. A 5 per cent 

 solution may be used to disinfect the unbroken skin, but on raw 

 surfaces, a 2 per cent solution is sufficiently strong. When applied 

 externally in full strength it burns the skin and causes it to turn 

 white. This burning action may be stopped by the application of 

 alcohol. In poisoning, alcohol, brandy, or whisky should be given. 



287. Acid, salicylic. A useful antiseptic, but irritating to the 

 tissues and but slightly soluble in water. A saturated alcoholic 

 solution is of value in the treatment of indolent sores and ulcers. 



288. Acid, tannic. Astringent. Dose J to 2 drams. Useful 

 internally in the treatment of diarrhea and dysentery, given alone 

 or in combination with other drugs. Externally it is used to check 

 bleeding from raw surfaces; in solution, in alcohol or witch-hazel, 

 it may be used to harden tender shoulders. It is also useful in the 

 form of an ointment, 1 to 4, for scratches, etc.
