dide of mercury, ammonia water, turpentine, hot water, 

 strong acids or alkalies, belong to this class, in some 

 cases they even destroy tissues. 



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 re- 

 membered that many of them are poisonous, hence must 

 not be left where children or animals can get at them 5 

 there are, however, some of them that may be used inter- 

 nally, such, however, should be used under the veterina- 

 rian's directions. Boracic acid, creolin, carbolic acid, 

 corrosive sublimate (bi- chloride of mercury), permangan- 

 ate 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, thereby preventing 

 or arresting putrefaction. Some members of this family 

 may be used for killing such parasites as lice, ticks, mag- 

 gots 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.,
