PROCEEDINGS OF THE SOCIETY.

beautifully done, and the mode of noting at the bottom all the particulars 
as to the power employed — the exposuro and other matters — was an 
extremely good one. He proposed that special thanks should be given 
for these and also for the number of parts sent to complete their sets 
of the Boston Natural History Society’s publications. 
This was put to the Meeting and carried unanimously. 
Mr. T. Charters White said he had looked at the photographs with 
a critical eye and thought they were the sharpest of the kind which he 
had seen for many years. Most of those shown in that room seemed 
to have been taken with too high powers and were consequently more 
or less blurred. These now exhibited were taken with a low power, 
X 25, and therefore they would bear enlargement without detriment. 
Mr. E. M. Nelson did not see anything specially excellent about 
these as photomicrographs, they were very simple objects taken with low 
powers with an ordinary camera lens and a gas-lamp. 
The President thought, with all deference to Mr. Nelson, that though 
these were, as he said, low-power objects, they were extremely fine 
specimens, and showed a large amount of useful detail for ordinary 
purposes. 
Mr. White said these would of course hardly rank with some higher 
power objects, of which he exhibited a specimen taken with an oil-lamp 
and power of x 156. The object was rather a favourite one of his — 
the developing tooth of a foetal kitten. 
Mr. Nelson said that on inspection it was clear that this was quite 
a different class of thing. 
The President said he might mention that he had received from 
Dr. Trouessart of Paris a single slide by post, in a kind of box which was 
new to him. It struck him as being extremely simple in construction, 
just a deep groove planed out of a strip of wood and another piece made 
to fit over it, so that they could be made in lengths and cut up to take 
the slides. And in addition to being cheap they were much more solid 
and therefore less liable to get crushed in the post. 
Mr. G. C. Karop said it was rather curious that he had himself 
received a box of the same kind a few days previously containing three 
slides, but unfortunately every one of them was broken badly in the 
transit. 
The President said they had a paper that evening by Prof. G. S. 
Brady, F.R.S., “ On Fucitrogus Bhodymenise , a Gall-producing Copepod.” 
It was hoped that Prof. Brady would have been present and would have 
read his paper to them, but he had been prevented from coming. 
Prof. Bell then, at the President’s request, gave a resume of the 
contents of the paper. 
The President said this form was one of great interest to the 
naturalist, and when a description of it came from a gentleman so well 
acquainted with the group as Prof. Brady it became doubly interesting. 
This struck him as being a most exceptional and remarkable form, and 
therefore as one of extreme interest. So far as he knew it was entirely 
unprecedented, and the fact that a copepod should be a gall-making 
creature was, to say the least, very extraordinary.
