Pomegranate root bark. — Wiv elTcctivc af^ainsf 

 taix'worms in ostriclis, but must l)c uiven in largo 

 doses and followed by a pnrgativ3. (Hutcheou). 



Sulphate of copper (bluestone). — This is !;ii excellent 

 taeniacide in calves and lambs bnt the doses for fowls 

 have not been determined. 



In some expe'rlmcnts which are now in progress I have given 

 GO<^c of a solution of 1 ounce sulphate of copper to 3 pints of 

 water to a full-grrown hen without noticing any ill effects from 

 the dose. Thirty™ of the same mixture killed a half-grown 

 rooster within twenty-four hours. Upon post-mortem it was 

 found that the worms in the intestine were dead. Another 

 half-grown chicken was dosed with 4.'oc of the same mixture 

 and bore the dose very well. 



I am not prepared to recommend bluestone for chickens at 

 present, except in experiments, and would direct attention to 

 the danger of allowing the solution to enter the windpipe, as a 

 very small dose of this solution will kill a fowl if the medi- 

 cine reaches the respiratory organs. As a safe method of ex- 

 periment, I have inserted a thin rubber tube to the crop (a 

 catheter would answer equally as well) and forced the medi- 

 cine through this tube. This method obviates the danger 

 mentioned and is borne very well by the chickens. I caution 

 again, that a large series of experiments in this line is needed 

 before bluestone can be recommended for general use in dosing 

 fowls. 



Perroucito advises the following treatment for tape 

 worms in chickens (dose for one chicken); 



(1) Aloesfsocotrineor carballine), 15 to 20 centigrams. 

 The animal is fasted the same day. 

 (2) Pumpkin seeds, 40 to 50. Administered to each 

 chicken on the second day. Or — 



(3) Male fern, powdered, 100 grauis. Mixed in bran. 



All of the above medicines should be procured as 

 fresh as possible. Many failures in treating for tape- 

 worms are due to the fact that old drugs have been 

 used which had lost their anthelmintic properties.
