POTENT WORM-DESTROYERS. 33/

 properties. 



Along about the eighth month — but it maybe much 

 earlier or much later — puppies are likely to become in- 

 fested with tapeworms, and although areca nut will often- 

 times expel these troublesome tenants there are other 

 agents that are more destructive to them, and with one of 

 these the reader should be fortified. 



Of the anthelmintics peculiarly adapted to this species 

 of worm, male fern is one of the most active ; and the 

 form and combination should be as follows : — 



Oil of male fern, one-half an ounce ; olive oil, one and

 the toys. 



This mixture, like all others containing disagreeable oils, 

 should be floated on a little milk, as previously advised 

 with worm medicines Nos. i and 2. 



For all varieties of medium or large size the doses of 

 the male fern mixture should be increased by one-half 

 when the second year has been entered ; while with the 

 largest breeds another and similar increase should be made 

 at the beginning of the third year — or in other words they 

 should then be taking two teaspoonfuls of the mixture. 



In every case when male fern fails to have the desired 

 effect, it should be administered again after an interval of 

 a week. 



Obviously in all cases where worm medicines, of what-

 should be comparatively empty that the drugs may be
