One paper has been published from the Laboratory 
this year, i. e., the one presented by me in the above 
programme on the liver of the Vulpine phalanger. It 
bears on an academic pathological controversy and is 
purely technical. 
Animal Parasites. 
Psittacic spiropteriasis. — Routine examination of newly 
arrived parrots to the number of 77 have resulted, as in 
the past years, negatively: and no parrots have come 
to autopsy showing these worms. Of the 77, 40 are in- 
cluded in the Australian shipment mentioned earlier in 
this report, and these were received with much interest 
because that continent was suspected as the source of the 
infestation. This suspicion arose because the Rosehill 
and Pennant's parrakeets had been the ones found most 
heavily and seriously infested, when we were investi- 
gating the disease in 1912; but none of these newly 
arrived birds, even the Rosehills and Pennant's, were 
found infested. 
Trichinosis in Paradoxure. — This animal showed other 
diseases, and the trichinosis was only incidental and not 
the cause of death. Microscopic examination of the 
cysts showed that the disease had lasted for many 
years (they were in part calcified); and from this, to-
