INTESTINAL PARASITES. Z-7 



while the latter should take no more than one-fourth of 

 the quantities advised. And the doses properly adjusted 

 they should be administered under the rules laid down — 

 that is, they should be given oxs an empty stomach, not be 

 repeated unless the patients are eight weeks of age, nor 

 should No. 2 be used until after that age and No. i ha& 

 been tried and found wanting. 



Here intrudes another delusion, namely, that it is always 

 necessary carefully to graduate doses of worm medicines 

 to the size of the patients. While in some instances varia- 

 tions can be made on this basis with perfect propriety, 

 great ones and nicety of adjustment are not invariably 

 required during puppyhood, for no very marked difference 

 exists between the alimentary canal of a puppy of medium- 

 sized variety and that of one of large breed. Certainly it i&- 

 not very much larger in one case than in the other; and 

 assuredly the difference in capacity counts but little. 

 Moreover, worm medicines are intended for the tenants, 

 not the hosts, consequently unless very powerful drugs are- 

 given — drugs that are largely absorbed and taken into 

 circulation — until matured a setter may be given as much 

 as a St. Bernard of the same age. But the latter, matur- 

 ing later, will bear increases after leaving the setter, and 

 until he, in turn, has reached maturity. 



Excluding small dogs,' for the reason that many of thero 

 are of notoriously delicate natures, the age and the condi- 

 tion of strength are the considerations that should weigh 

 most when estimating doses of worm medicine, or at least 

 medicines of the nature of those herein recommended. 



Returning to Worm Medicine No. i, the reader is again 

 reminded that it is never wise to give medicine of any 

 kind to very young puppies unless they positively require 

 it; also, that vermifuges should be withheld until after 

 the eighth week unless there is evidence that worms are
