PROCEEDINGS OF SOCIETIES. 
Without any wish to thrust the matter upon Mr. Wenham’ s further 
attention, I still would like Mr. W. to be notified that the objective is 
forwarded for the purpose of trial by him of its angle in balsam. 
Adjusted at “ 10^-” closed from open point (which is the inter- 
mediate point of the whole adjustment), I make the angle in balsam, 
using the tank as proposed by Mr. Wenham, 93°, or possibly 95° by 
sunlight. 
With a view to help to a conclusion, perhaps you will have no 
objection to giving Mr. Wenham notice of receipt of the objective, 
and that it is for his use, for the purpose aforesaid, if he chooses to 
subject it to the test. 
N.B. — I easily remove the balsam with a little cool oil, and no 
harm to lacquer or glass. 
With much respect,

P.S. — Further remarks on account of experiments on angular 
aperture shall be forwarded per steamer of 23rd inst. from this port.

[The Editor begs to say that he has not received any objective from Mr. Tolies 
up to the date of August 13th.]
