608 THE VETERINARY SCIENCE 



Action and Use. — It has a very cleansing effect on a 

 wound, and is greatly used for that purpose. It is also used 

 for fumigating stables by sprinkling a little around on the 

 floor. It is very rarely, if ever, used internally. The strength 

 in which carbolic acid should be used in bathing a wound is 

 10 drops to half a pail of water. For a lotion use 20 drops to 

 a pint of water. For making carbolic oil use 25 drops of 

 carbolic acid to a half-pint of olive or sweet oil, that is about 

 two or three drops of acid to the ounce of oil. ^ It is a mistake 

 to put too much acid in a wash or lotion, as instead of it 

 having a cleansing effect it will then burn the wound and 

 stop the healing action. A very good healing salve is made 

 out of 5 drops of carbolic acid to an ounce of vaseline.
