PROCEEDINGS OF SOCIETIES. 
Royal Microscopical Society. 
King’s College, October 3 , 1877 . 
H. C. Sorby, F.R.S., Esq., President, in the chair. 
The minutes of the preceding meeting were read and confirmed. 
A list of donations to the Society since June 6 was read, and the 
thanks of the meeting were returned to the donors. 
The President informed the Fellows that efforts had been made to 
arrange for a scientific evening, to be held on Wednesday, October 31, 
and although they were not sufficiently completed to enable him de- 
finitely to announce the meeting, no doubt the necessary permission 
would be obtained, in which case due notice would be given in the 
usual way.* 
The President then gave a resume of his paper “ On an Im- 
proved Method for Distinguishing the Axes of Doubly Refracting 
Substances.” Numerous diagrams were drawn upon the black-board 
in illustration of his remarks, and a slide containing the wedge- 
shaped section of quartz which he employed was exhibited in the 
room. 
Mr. M. H. Johnson asked if Mr. Sorby would kindly explain 
which way the quartz was cut with regard to the crystallographic 
axis ? 
The President said it was cut parallel to the positive axis. 
The thanks of the meeting were unanimously voted to the 
President for his communication. (The paper will be found at 
p. 209.) 
A paper by Mr. F. H. Wenham, “ On the Aperture of Object- 
glasses,” was read by the Secretary. It described an improved 
method of ascertaining the true angle of aperture as distinguished 
from angle of field. (The paper will be found at p. 212.) 
A vote of thanks to Mr. Wenham for his paper was unanimously 
passed. 
At the request of the President, who expressed his regret that 
Mr. Wenham was not present, Mr. Ingpen made some remarks upon 
Permission has since been obtained.
