PROCEEDINGS OF THE SOCIETY. 
MEETING 
Held on November 16tii, 1898, at 20 Hanover Square, W. 
E. M. Nelson, Esq, President, in the Chair. 
The Minutes of the Meeting of October 19th ; . 1898, were read and 
confirmed, and were signed by the President. 
The President, on behalf of the Council, gave notice that at the next 
meeting of the Society the suspension of Bye-law 36 would be moved. 
The President having requested Mr. A. D. Michael to take the chair, 
read a paper describing a very large binocular Microscope made and de- 
signed by a friend. The description was illustrated by an excellent- 
photograph of the instrument shown upon the screen. 
Mr. Michael said he was quite sure it would be the pleasure of the 
meeting to pass a very hearty vote of thanks to the gentleman who had 
so kindly sent the photograph, and also to the President for his remarks 
upon it, in which he had so clearly put before them the details of the 
construction of this very elaborate instrument. 
A vote of thanks was accordingly put from the chair and canied 
unanimously. 
Mr. Michael said that Mr. Curticshid brought a number of slides of 
diatoms for exhibition that evening ; and that Messrs. Beck also ex- 
hibited two of the original slides of Amphipleura pellucida mounted by 
Prof. Hamilton Smith in his high refractive medium. These were shown 
under 1/12-in. oil-immersion objectives of numerical apertures of 1*0 
and 1*25 respectively, the diatom under the former satisfactorily show- 
ing resolution, while that under the latter was perfectly resolved. 
Mr. Michael said they were much obliged to those gentlemen for 
their exhibits, and especially so to Mr. Curties for bringing before them 
so many excellent examples of the advantages of mounting these difficult 
objects in high refractive media. 
Mr. Yezey said the exhibition sub-committee of the Council were 
particularly indebted to Mr. Curties on that occasion, because he had 
come to their assistance at very short notice ; and had very kindly come 
down with this very beautiful series of slides, so that the Fellows of the 
Society and their friends should not come to the meeting and find there 
was no exhibition. 
The thanks of the Society were then cordially voted to Messrs. 
Curties and Beck for their exhibits. 
The Secretary said a paper had been received from Mr. Arthur 
William Waters, on ‘ Bryozoa from Madeira.’ The paper itself was 
too long to be read in exienso, lie would therefore give a short resume of 
it, and it would be printed in full in the Journal.
