ANTISEPTIC AND ANALGESIC 421 



benefit chronic bronchitis and lung complaints, when accom- 

 panied by excessive or foetid discharges. Parasites lodged 

 in the air-passages are destroyed by creosote, administered 

 by the mouth, or, more effectually, by inhalation, or 

 intratracheal injection. In gangrenous equine pneumonia 

 creosote has been given intratracheally with some advantage 

 in relieving distressed breathing and irritable bowels. It 

 has been tried in purpura in horses, but without any very 

 striking results. Nasal gleet, with enlarged glands and 

 foetid discharge, is sometimes, however, benefited by a daily 

 drachm of creosote, made into bolus with linseed meal. 



For external purposes, carbolic acid has superseded 

 creosote as an antiseptic for wounds, but as a stimulant 

 and escharotic in caries, fistula, canker, thrush, and foot- 

 rot, creosote with an equal part of tincture of iodine, is 

 still used. Diluted with alcohol and water, or with vinegar, 

 it is occasionally used to relieve itching and remove scurf 

 in chronic eczema, prurigo, and psoriasis. It destroys 

 parasites infesting the skin. For mange and scab, Gerlach 

 advised an ounce of creosote, dissolved in fifteen ounces of 

 spirit and forty of water. For intractable follicular mange, 

 after washing the dog with soap and water, or, better still, 

 shaving him, Hunting advises inunction of a mixture of 

 one part of creosote and fourteen of olive-oil, the penetrating 

 power being increased by the addition of two parts solution 

 of caustic potash. Human patients suffering from tooth- 

 ache depending on caries are often relieved by a drop of 

 creosote cautiously placed in the hollow of the tooth. 



DOSES, etc. For horses, lT\xxx. to lT|Jxxx. ; for cattle, 

 f 3i. to 3Jv. ; sheep, Tl\xx. to lT[xxx. ; pigs, TT[v to H|xv. ; 

 dogs, H\i. to H\v. It is given in bolus or pill with syrup ; 

 in emulsion, with mucilage, or oil ; in six parts of alcohol, 

 or in aqueous solution one per cent. ; or conveniently 

 shaken up with milk. As a stimulant or escharotic, it is 

 applied with a camel's-hair brush ; is used in solution 

 in spirit or acetic acid, or as an ointment, made with one 

 part to eight of lard or simple ointment. For skin diseases, 

 equal parts of creosote and sulphur may be made into an 

 ointment with lard, or a liniment with oil. A few drops 

 are sometimes added to turpentine, ammonia, or other
