THE EYE- WORM. 87 



mixed in meal or dough. These pills should be 

 (riven every other day for about a week. About an 

 hour or so after each pill, a teaspoouful of sweet oil 

 should be administered. Disinfection of the ground 

 where the birds had been should be carried out 

 as described before, as the Heterakis eggs may 

 remain in the runs for some time— in fact, until they 

 are eaten by other fowls. 



The Eye-worm. 



Even the sensory organs of poultry are not exempt 

 from vermiceous parasites. In China we are told 

 by Dr. Cobbold that there is a minute Filarian worm 

 (Filaria Mansoni) that lives in the eyes of fowls. This 

 is of no unusual occurrence. Similar instances have 

 been recorded in horses. But of course these are only 

 accidental cases of parasitism. 



In conclusion may be mentioned a case of a serious 

 choleraic affection in Cochin-China Fowls, quoted by 

 Zurn. In these fowls, in which violent diarrhoea 

 set in, causing debility and speedy death, there were 

 observed in the walls of the intestines quantities of a 

 minute Nematode worm known as Anguillula stereo- 

 rails, which were undoubtedly the cause of the 



complaint. 



A fuller account of parasitic worms will be found 

 in an article by the writer in the Journal of the 

 S.E. Agricultural College (No. 4).
