Dr. Weidman has reported the discovery of an arach- 
noid parasite, Pneumonyssusfoxi, in the lung of a monkey, 
in the Journal of Parasitology, September, 1915. 
The Museum has been enriched during the year by 
105 new specimens. The total of exhibitions is 790 
including 56 from human sources. To accommodate this 
addition four new museum stands have been installed. 
Several new pictures have been hung. Practically all 
the important lesions of wild animals are to be found in 
our collection and a descriptive index has been completed. 
The high price of potassium permanganate has com- 
pelled the adoption of some other method to generate 
formaldehyde gas. Experiments have been made as 
to the value of spraying diluted formalin in the strength 
of 2 pints per 1000 cubic feet of enclosed space. This has 
proved satisfactory for all but objects wrapped in more 
than one layer of bagging. For our exhibition houses 
this will answer very well. The Bird House has recently 
been fumigated on account of the small epidemic there 
(see page 29). Experiments upon the use of sulphur 
dioxide, a good method of killing bugs, demonstrated 
that the galvanized iron would not resist the sulphurous 
acid so that method could not be adopted. 
The following is a list of the animals dying during the 
year. The total will be found not to tally with the records 
upon the table, as some specimens have died from injury 
and some were decomposed. Moreover, in many in- 
stances animals are included in the figures of more than 
one heading, since lesions of importance may have been 
found in more than one of the anatomical systems. 
It is seldom the case that only one of the systems is 
sufficiently affected to be the only cause of death.
