LIQU1D ANTISEPTICS 



One of the best liquid antiseptics is a solution of bichlor- 

 ide of mercury (corrosive sublímate) in water. One gram of 

 bichloride of mercury is dissolved in one liter (iooo C. C.) of 

 rain or distilled water, as the mercury does not mix well with 

 well water. This solution is colorless and odorles. It should 

 be plainly labelled. 



Another excellent antiseptic is a solution of carbolic 

 acid in water. 



For ordinary purposes in the treatment of wounds a sol- 

 ution of 30 grams ofpure carbolic acid, dissolved in 1000 C. C. 

 of water makes a good antiseptic. This is a three per cent 

 solution, or one part ofacid dissolved in 33 parts of water. If 

 a wound is discharging pus or smells badly, or in punctured 

 wounds of the foot, a five per cent solution of carbolic acid 

 can be used a few times. A five per cent solution is made by 

 dissolving 50 grams ofacid in 1,000 C. C. of water, or using 

 one part of acid to 20 parts of water. After disinfecting the 

 wound a few times with the strong solution, then % use the 

 weaker or three per cent solution. From our experience we 

 prefer to use the 5 % solution a few times on a badly. 

 infected wound until it is well disinfected and then use the 

 solution of bichloride of mercury in the strength of I to 1,000 

 parts of water. 



Another common and excellent antiseptic is creoline 

 mixed with water. It forms a milky emulsión with a strong 

 odor and is good to preveut screw-flies from laying their eggs 

 in wounds. Creoline is used in the same strength as carbolic 

 acid, that is 5 % for the first disinfection and after this in a 3 % 

 solution. 



An antiseptic and astringent solution that is useful for 



sores such as are caused by the friction of harness saddle is 



as follows: 



Acétate of lead 24 grams. 



Sulfate of zinc. 30 " 



Water 1 liter. 



Shake this solution well before using.
