7. Antiseptics. This class of drugs has revolutionized 

 both human and veterinary surgery and there is proba- 

 bly no one class of medicines that will pay the stockman 

 as handsome a profit in their use as will the antiseptics. 

 Contagious diseases and wounds become less formidable 

 to handle if antiseptics are used plentifully, consequently 

 the stockman should never let his supply of these useful 

 drugs be exhausted. Fortunately the class is a large 

 one and a selection can be made quite easily. It must 

 be remembered that many of them are poisonous, hence 

 must not be left where children or animals can get at 

 them; there are however some of them that may be used 

 internally, such, however, should be used under the 

 veterinarian's directions. Boracic acid, creolin, carbolic 

 acid, corrosive sublimate (bichloride of mercury), per- 

 manganate of potash, tar, bluestone are antiseptics in 

 common use, and the list is constantly being added to; 

 besides these the various proprietary articles to be found 

 on the market, such as chloro-naphtholeum, germol, 

 zenoleum, possess antiseptic properties to a greater or 

 less degree. Antiseptics act by destroying germs, there- 

 by preventing Or arresting putrefaction. Some members 

 of this family may be used for killing such parasites as 

 lice, ticks, maggots found on the bodies of farm animals. 



The actions of other drugs have also served to group 

 them, e. g., medicines acting on the kidneys, thereby 

 increasing the urine are termed Diuretics; those that 

 lower the temperature of the body, as in fevers, etc.,
