Joes not terminate fatally for a number of weeks or 

 perhaps not at all. In other cases, death results verv 

 quickly. The tenrination depends upon the strength 

 of the fowl and the number and variety of the worms. 

 If the worms are present in sufficient numbers to ea- 

 tire occlude the intestine, death is produced very 

 quickly. 



Another species of round \vorm, Heterakis maculose, 

 has occasiored great loss among birds. This worm is 

 white, cylindrical and 

 pointed at each end; the 

 male is about an inch 

 long and the female one 

 and a quarter inches. 

 Sometimes several hun- 

 dren of them are found 

 in the intestine of a sin- 

 gle pigeon.

remedy recommeided by Baronio, consisting of equal 

 pai'ts of the root of male shield fern, tansy and savory, 

 of which mixture one drachm is made into a tea with 

 six ounces of water and this fluid is mixed with suffi- 

 cient flour to form pills and these are administered to 

 the infested fowls. Or, the powdered areca nut may 

 be given in doses of from thirty to forty grains for 

 chiekeus and fifteen grains for pigeons. 



The prevention of disease resulting from the pres 

 ence of the round worms may be accomplished by en- 

 forcing the general regulations recommended above, 

 in connection with the discussion of tapeworms. The 

 frequent removal and the care of the niainire is very 

 important.
