POTENT WORM-DESTROYERS. 339 



ride of ammonium, two drachms; fluid extract of senna, 

 six drachms ; water sufficient to make three ounces. Dose, 

 one teaspoonful twice daily, in a little water, between the 

 feedings. 



This dose is appropriate for all breeds excepting the 

 small and toy. For the former the dose should be one-half 

 a teaspoonful, and for the latter one-fourth of a tea- 

 spoonful. 



The week of preparation having ended, the night before 

 the male fern is to be administered, and four or five hours 

 after the patient has had a light supper, a goodly dose of 

 castor oil should be given. Then, the bowels having been 

 thoroughly evacuated and the tapeworm uncovered, as it

As the wormseed oil and santonin mixtures — Nos. I

 a cathartic; and here again the preference should be given 

 to castor oil, and the dose of the same graduated according; 

 to the age as follows : — 



For all puppies six months of age, excepting small breeds' 

 and toys, it should be one tablespoonful. For the S7nalt 

 breeds it should be one-half a tablespoonful ; and for toys, 

 one teaspoonful. 



After this age and up to the twelfth month the doses 

 for all varieties can be gradually increased until they are 

 nearly or quite doubled ; and rarely will further increase 

 be necessary for the toys, small and medium-sized breeds, 

 but for the largest dogs three tablespoonfuls of the oil is 

 generally required for very decided effect. 



Attention is again called to the fact that puppies in-
