On tlie motion of the President, special votes of thanks were 



accorded to Mr. Badcock, the representatives of the late Mr. Chas. 



Brooke, Dr. Gray, and the representatives of the late Mr. J. 

 Waterhouse, for their respective donations. 



Mr. Crisp mentioned that during his absence abroad the paper at 

 p. 653 of the October number of the Journal had been printed from 

 the author's original MSS. instead of from the revised MSS., for 

 which it had been held over. The corrected pages would be sup- 

 plied with the next number. 



The following Note from Mr. Wenham was taken as read : — 



As statements have been made to the effect that I altogether deny 

 the possibility of obtaining an angle on a balsam-mounted object 

 beyond 82^, the following references will show that, excepting under 

 certain conditions, I have not made such an assertion, which, as it 

 appears recorded with my name attached in the ' Proceedings ' of the 

 Society, calls for a notice that it would not otherwise have received 

 from me. 



I must therefore state positively, that I never held, and do not 

 hold, any such opinion. The discussion has been long and not very 

 definite, and sufficient attention may not have been given to par- 

 ticulars by some attributing this error to me — to be excused for this 

 reason. 



In ' Quart. Journ. Micr. Science,' vol. iii. (1855) p. 303, for 

 the purpose of remedying the loss of aperture on an object in balsam 

 from a dry object-glass, I describe the adaptation of an additional 

 lens in front connected with the cover by a refractive intermedium, 

 thus securing the full eflFcct of aperture. 



In 'Monthly Microscopical Joui-nal,' vol. v. (1871) p. 17, I 

 state that " An angle of 82'' cannot be exceeded in a dry objective, 



* The bottle in which this was sent was broken in transit tlu'ough the post, 

 and the contents had disappeared.
