PROCEEDINGS OF THE SOCIETY. 
which it would be likely to produce ; but as every one who made draw- 
ings in this way adopted some method of comparison, he did not think 
there was very much in the communication which could be noted as 
being new. 
The President thought perhaps the great amplification might be 
exceptional. 
Mr. Michael said it was unusual, but it had often been done. 
Prof. Bell said they had just received a note from Mr. J. C. Wright, 
of Edinburgh, on some Rotifers which he had found attached to a newt. 
The communication was accompanied by some drawings, which were, 
unfortunately, not sufficiently clear to render it by any means con- 
clusive that what he had found was a Rotifer ; it was, in fact, difficult 
to say exactly wbat it was, though probably it might prove to be a 
specimen of Vorticella. 
Prof. Bell said they had also received a communication from Mr. 
F. R. Dixon-Nuttall, who sent a Furcularia, with a description which 
might show that it was a new species. It had only just come to hand, 
so that there had been no time to examine it ; but he suggested that 
they could not do better than to send it to Dr. Hudson, with a request 
for his opinion upon it. 
Mr. W. M. Osmond's paper, in which he described a simple apparatus 
for adapting a camera for the purpose of photographing objects direct 
from the Microscope, was read by Prof. Bell. It was illustrated by 
photographs showing the arrangements described, for which the merits 
of steadiness, cheapness, and compactness were claimed. 
Dr. Dallinger said this arrangement was, no doubt, simple, and it 
would very likely be useful for very low power work, but he doubted if 
it was likely to be of value if applied to moderate or high powers. It 
appeared from the photograph to be clamped to the end of the camera 
and again to the pillar, with what was certainly a relatively long interval 
between the clamping-screws. Those who did work of that kind, espe- 
cially with high powers, knew that it was of the utmost importance that 
they should have great rigidity between those two points, and, having 
regard to the structure of this apparatus, he should be afraid that it 
would be found that there was too much vibration in practice. 
Mr. C. L. Curties thought it was certainly a very convenient form, 
but he should be sorry to have to use it for anything beyond a 1/2-in. 
objective, or with a magnifying power of over 100 diameters, feeling 
that with such a method of construction it would be impossible to get 
sufficient steadiness for use with higher powers. 
The following Instruments, Objects, &c., were exhibited:— 
Surgeon P. W. Bassett-Smith, li.N. : — Twelve Slides of Deep-sea 
Deposits, illustrating his paper. 
Mr. F. Chapman : — Foraminifera, illustrating his papor.
