172 WORMS INFESTING THE DOG. 



mixed with a table-spoonful of lemon-juice, and given at night to 

 a dog previously starved for twenty-four hours, and a dose of oil 

 administered in the morning. The remedy should be repeated at 

 the end of a week, and again in a month or two. It is, perhaps, 

 as well, in order to make sure that the whole animal is expelled, 

 to examine the worms passed for the head, which is about as large 

 as a very small horse bean, with a long narrow neck. Like 

 Indian pink, and, indeed, all other worm medicines, Kousso has 

 sometimes produced mischief, and it cannot certainly be regarded as 

 perfectly safe. As a general rule, however, it is an innocent 

 remedy, and no doubt it is a very effective one. The areca-nut, 

 if administered according to the directions given at page 170, will 

 generally clear the dog of tape-worm ; but it sometimes fails, and 

 I have repeatedly known Kousso succeed afterwards. The leaves 

 and oil of the root of the male fern are strong in their power of 

 destroying tape-worm. The plant should be dug up in the summer, 

 and the top powdered, and carefully preserved in a stoppered 

 bottle. The dose is from one to two drachms made into a bolus, 

 and followed by a dose of oil in a few hours. Of the oil which is 

 sold in the shops eight to ten drops form the dose administered 

 in a bolus, and repeated the next morning. 



The following are the doses of each vermifuge, which must 

 be varied according to the age and strength of the patient : 



Areca-nut (Nux arecd). Two grains to every pound the dog weighs. 

 Stinking Hellebore (Helleborus fcetidus). One grain to every six pounds the 



dog weighs, mixed with double its weight of jalap. 

 Indian pink (Spir/elia Marilandica}. Half an ounce to be infused in a pint 



of boiling water. Then give a full-grown dog from one to two table-
