of the year, from March to August. One was found in No- 
vember, 1909, and one in January, 1910. In 1908 the 
greater numbers of deaths from these proventricular worms 
was also during the spring and summer months, and in last 
year's report it was suggested that the infection was sub- 
siding because of the scarcity of cases in the second six 
months of the year. While there have been fewer cases, 
the seasonal appearance of the deaths is repeated. The 
disease is very common among the Rosehill Parrakeets, 
20 out of 29 of these birds coming to autopsy in five years, 
showing it. A new lot of four of these birds arrived in 
February, 1909. Three of them died with the worms within 
three months. It may be that they introduced the in- 
fection, but where it came from originally we have of course 
no knowledge. Two other birds have had filarial worms 
in the proventricle. They are Green Glossy Starling and 
Sulphur Breasted Toucan. They were kept at the end of 
the Aviary most distant from the parrots. The worms 
found seem similar to the parrot worms but I am not sure 
they are the same. 
General Parasites. 
They have been the common varieties in the usual sites, 
with exception of a few cases of partial obstruction of the 
stomach of opossums. This was caused by a great number 
of nematodes attached firmly in the mucosa by the head. 
The cases of two wild cats dying in February, 1910, are 
interesting. They had many filarial worms coiled up be- 
tween the great gluteal muscles on both sides near the sacral 
and caudal insertions. 
Blood. 
Attention has been given to the routine examination of 
fresh blood preparations, just after autopsy. These have 
not resulted in the finding of many parasites. Dr. A. C. 
Abbott is now receiving blood smears from every animal, 
provided it be not too far decomposed. He kindly offered 
to report to us his findings, and has done so when they dis-
