Pomegranate root baik. — Very effective against 

 tapeworms in ostrichs, but miisi be ^iven in large 

 doses and followed by a purgativs. (Hutclieon). 



Sulphate of copper (bluestone). -This is :\n excellent 

 taeniacide in calves and lambs but the doses for fowls 

 have not been determined. 



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

 60cc of a solution of 1 ounce sulphate of copper to 3 pints of 

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

 the dose. Thirtycc 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 4oc-c of the same mixture 

 and bore the dose very well. 



I am not prepared to recommend blue stone 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 th^e chickens. I caution 

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

 before bluestone can be recommended for g-eneral use in dosing 

 fowls. 



Perioucito advises the following treatment for tape- 

 worms in chickens (dose foi' one e-hickeu): 



(1) Aloes (socotrineoi- carballine), 1.5 tc 20 centigrams. 

 The animal is fasted the same day. 

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

 chicken on the second day. Ur — 



(8) Male fern, ])o\\dei'ed, 100 grams. Mi.xed in biau. 



All of the above medicines should be procured as 

 fresh as possible. Many failures in treating for tape- 

 wo'rms are due to the fact that old drugs have been 

 used which had lost their anthelmintic pi'o])ei'ties.
