PROCEEDINGS OF THE SOCIETY. 
d’Orleans’ ‘La Vision Parfaite,’ published in 1677, where the inventor of 
the instrument figured and described it in full detail. He (Mr. Mayall) 
had dealt with the subject somewhat fully in his Cantor Lectures in 
1885, and had given a photozincograph from the original figure, and he 
exhibited the original work to the meeting. He thought, therefore, it 
would be unnecessary to give any extended publication to Mr. West’s 
notes, especially in view of the fact that twelve pages of the MS. were 
devoted to translations of passages relating to the binocular telescope, 
whilst little more than a page was devoted to those on the binocular 
Microscope. 
The Chairman thought that without the reproduction of the figures, 
both from Cherubin d’Orleans’ work and from the first and second 
editions of Zahn’s work, the subject could not be thoroughly explained. 
In Harting’s ‘ Das Mikroskop ’ several figures were given from Zahn’s 
work, in some of which two tubes were shown converging in an upright 
form. 
Mr. G. F. Dowdeswell’ s paper, entitled “ A Contribution to the Study 
of Yeast — No. I. Baker’s Yeast,” was read by Prof. Bell. Culture-tubes 
containing specimens illustrative of the subject were handed round for 
inspection. 
The thanks of the Society were given to Mr. Dowdeswell for his 
communication. 
Mr. C. D. Sherborn read some portions of a paper which had been 
prepared by himself, conjointly with Mr. H. W. Burrows and the Rev. G. 
Bailey, on “The Foraminifera of the Bed Chalk of Norfolk, Lincoln- 
shire, and Yorkshire.” The paper contained a long list of the genera 
and species described, and was illustrated by numerous drawings. 
The Chairman, in moving a vote of thanks to the authors of the paper, 
said that the Council’s sense of the value of the communication might 
be judged from the fact that they had decided to allow four plates to 
be prepared in illustration, which was considerably beyond the limit of 
expense to which they felt justified in going under ordinary circum- 
stances. 
The thanks of the Society were voted to Messrs. Sherborn, Bailey, 
and Burrows for their paper. 
The Chairman said he thought that was the largest meeting they had 
yet had in the month of June. It concluded their meetings for the 
present session, and they would therefore adjourn until Wednesday, 
October 15th. 
The following Instruments, Objects, &c., were exhibited:— 
Mr. G. F. Dowdeswell: — Culture-tubes of Micro-organisms from 
Baker’s Yeast. 
Mr. E. M. Nelson : — Slides of the Bordered Pits of Pinus, and 
Diatom-structure. 
Mr. A. Pringle : — Improved Photomicrographic Apparatus. 
Mr. C. Rousselet : — Larval Ascidians, tadpole stage. 
Mr. W. B. Strugnall : — Specimens of Patella pellucida.
