REPORT OF THE 
< 
maintained during the past year. The general every-day 
work done by various members of the section is scarcely of 
a character to be appreciated in a report, but must be inspected. 
As in previous years, an exhibition of photographic work done 
by the members was held in the Museum on the 7th and 8th 
December, 1893, thus giving the members of the Yorkshire 
Philosophical Society generally an opportunity of judging 
for themselves of the quality of the work carried on by this 
special section. A few eminent amateur and professional 
photographers very kindly lent a considerable number of 
their photographs to this local exhibition. The great pictorial 
merits and scientific value of these were highly appreciated 
and added largely to the success of the conversazione. The 
exhibition of lantern slides given by the photographic section 
in March was very highly appreciated, judging from the 
very crowded condition of the Lecture Theatre on that night. 
The section has certainly every encouragement for repeating 
these exhibitions of transparency work in the future. 
The council have pleasure in announcing that in accordance 
with the powers conferred on them by section vii. of the rules, 
they have approved a scheme by which persons not members 
or associates of the Philosophical Society may be admitted 
to the meetings of the photographic section only, on payment 
of a small annual subscription. 
Comparative Anatomy.— The only addition made to this 
department consists of a skeleton of the Otter (Lufra vulgaris) 
prepared from a carcase purchased by the Society. 
Dr. Jonathan Hutchinson lias called attention to the fact 
that a lion’s skeleton in our collection shews the results of 
Periostitis. This disease, a rare one in animals, was believed 
to be confined to the domestic dog until it was observed some 
little time since in the skeleton of a lion in the Dublin 
Museum. The latter was the skeleton of a menagerie-kept 
lion, and therefore the case is practically that of a domestic 
animal. It would be a matter of great interest to know 
whether our skeleton is that of a wild animal or not. 
Unfortunately the history of this skeleton has been lost.
