ZINC SALTS. 637 



Tartar Emetic 



seems, when given internally, to stimulate the glands of the skin, 

 the appearance of which it consequently improves. It is a valuable 

 worm medicine (p. 398). It is also used to increase the action of 

 aloes. Such large quantities as 1 oz. or more, administered daily 

 for several days, have been borne with impunity. As a rule, about 

 ^ lb., given at one time, will kill a horse ; 15 grains a man ; and 

 5 grains a dog. Dose, 1 to 2 drachms daily in the food. 



Turpentine 



may be given internally, as an astringent, in 1 oz. doses three 

 times a day. For destroying worms in the intestines, it should be 

 given in full doses of, say, 4 oz. In doses of 2 oz. it is very useful 

 in cases of flatulent colic. When given internally, it should always 

 be combined with linseed or other sweet oil or with gruel, so that 

 it may not injure the mucous membrane of the mouth, gullet, etc. 

 It is an admirable antiseptic (p. 68). 



Vaseline. 



For making up ointments, vaseline has the advantage of not 

 being affected by the air. But for this purpose it is not as good 

 as lard, for its melting point is lower, and it is apt to spread 

 and leave the agent, of which it is the vehicle, to dry upon the 

 surface of the skin. By itself, it is useful in skin diseases.
