POTENT WORM-DESTROYERS. 335 



three-fourths of a teaspoonful ; the tenth month an even 

 teaspoonful ; while once fully matured they can safely be 

 given nearly one and one-half teaspoonfuls. 



For all puppies of varieties of medium size, as collies, 

 the dose of areca nut should be increased by one-half a 

 teaspoonful every second month until the sixteenth month 

 is passed ; that is, commencing with one teaspoonful 

 after the fourth month, after the sixth it should be 

 one and one-half ; the eighth, two ; the tenth, two and 

 one-half ; the twelfth, three ; the fourteenth, three and 

 one-half ; the sixteenth, four ; and this should be the 

 dose thereafter. 



The reader is reminded that the basis of these estimates 

 is an even teaspoonful. 



In adjusting the doses of areca nut for the largest breeds, 

 precisely this same method of increase should be employed ; 

 that is, commencing with one teaspoonful after the fourth 

 month if this dose is increased by one-half a teaspoonful 

 every second month, in the sixteenth it will be the same 

 as for medium-size breeds. But the increase should be 

 persisted in, and in the same ratio, until after maturity, 

 which is about the twenty-fourth month. In other words, 

 the dose after the eighteenth month will be four and 

 one-half teaspoonfuls ; the twentieth, five ; the twenty- 

 second, five and one-half ; and the twenty-fourth, six. 



Doses estimated on these lines are only of moderate 

 size, yet, as a rule, they are quite as effectual as much 

 larger doses. And it is always better in cases of worms 

 to resort to fairly small doses and repeat than give a 

 single very large one. 



When giving powdered areca nut to quite young pup- 

 pies the best vehicle is milk ; but the quantity should not 

 be over a tablespoonful, for force must be used in adminis- 

 tration.
