Carbolic Acid.— This important medicine is obtained from coal tar 

 oil. Its smell resembles that of creosote. 



CTse.s.— It isused for various purposes, such as a disinfectant in stables 

 where animals have distempers, fevers, etc. , by washing the stalls, floors 

 and ceilings with water which contains a small quantity of the acid; also 

 used, with gratifying results, for unhealthy wounds and sores, by applying 

 a solution of the following strength: Carbolic acid, one ounce; fresh soft 

 water, six pints; this prevents putrefaction, and will cause the wound to be 

 more healthy and to heal sooner. Carbolic acid is also used for destroying 

 wood ticks, lice and all kinds of parasites, and is quite effective in preventing 

 the hot fly from depositing her eggs when those parts which are commonly 

 chosen by the bot fly are washed with a solution double the strength given 

 above. 



Nitric Acid, (called, also, Aqua Fortis).— This is also a valuable tonic, 

 when properly given. It is extremely sour and corrosive, and should be 

 guarded by the same caution as in giving the sulphuric acid. 



Bone.—li maybe given in doses of five to twenty-five drops, largely 

 diluted with water. 



Sulphuric Acid, (called, also. Oil of Vitriol).— This acid is obtained by 

 burning sulphur, mixed with one-eighth of its weight of nitre, over a 

 stratum of water contained in a chamber lined with sheet-lead. 



Uses. —Many consider this acid to be preferable to any other of the acids 

 for internal use, in debility of the digestive organs, for general weakness, 

 and as a refrigerant. 



Externally, it is used similarly to muriatic acid. When it is desired to 

 use it as a caustic it should be mixed with dry powdered white vitriol, suffi- 

 cient to make it of a pasty consistence, so it can be confined to the location 

 which it is desired to cauterize.
