PROCEEDINGS OF THE SOCIETY. 
improvements made in liis apparatus for tlio production of pure mono- 
chromatic light for use with the Microscope. 
The thanks of the meeting were voted to Mr. Nelson for his com- 
munications. 
The Secretary read a letter of acknowledgment from M. Edouard 
Bornet, of Paris, on the receipt of the announcement that he had been 
elected at the last meeting an Honorary Fellow of the Society. 
Mr. A. W. Bennett gave a resume of his paper “ On the Freshwater 
Algae of South-west Surrey,” describing, amongst others, some six or 
eight new species found during his recent vacation in the neighbourhood 
of Haslemere and Hindhead, drawings of which were made upon the 
blackboard in illustration of the subject. 
The President expressed the indebtedness of the Society to Mr. Ben- 
nett for his very interesting communication, which was just the kind 
they wanted. The advantage of working steadily on at the same subject 
was abundantly shown here by the fact that he had succeeded in adding 
several new species to those already known. His observations on the 
life-history of these things were also very interesting, especially the 
little notes on the way in which they carried out their life in its repro- 
ductive and sporing processes. They were specially glad to get papers 
of this kind from Mr. Bennett upon what was in this country a rather 
neglected subject, and he ventured to express the hope that as further 
opportunities occurred he would continue his observations. 
Prof. Bell said they had also received a paper from Dr. Alfred C. 
Stokes, descriptive of a number of new species of American Infusoria, 
which would be taken as read, and would appear in the Journal in due 
course. 
The President reminded the Fellows that the Society’s Conver- 
sazione would take place on November 30th as already intimated.
