A number of birds that we examined in the winter died from in¬ 
testinal irritation ; associated with this condition a parasite called 
the heterakis was found, and the point arises whether its presence 
causes the intestinal irritation and body w’asting. As an anatomist 
and surgeon, I do not feel sufficiently in touch with the subject of 
parasitology' to give an opinion on this point. 
FilARIA.— During the year there has been a mortality amongst 
the magpies (gymnorhina). — These birds have presented the 
synyatom of loss of weight—emaciation. Professor Gilrutli has 
kindly examined the blood of these birds and he reports constantly 
finding filaria in the blood. In the absence of other apparent causes of 
death and the coUvStant presence of this parasite it appears probable 
that filaria in magpies is the cause of the fatality that has occurred. 
An English magpie that died also .showed this same parasite.

cus infection.

infection.

food.
