REPORT. 



In presenting the Twenty-third Annual Report your Committee 

 have the pleasure of again recording the continued prosperity of 

 the Society. They deeply regret the loss which the Society has 

 sustained by the death of two of its Vice-Presidents, viz., Mr. T. 

 H. Hennah and Sir J. Cordy Burrows ; the former was one of the 

 earliest Members of the Society, and had always taken a very 

 active part in promoting its prosperity, and in the diffusion 

 of scientific knowledge, particularly in those branches of science 

 which depend upon the use of the microscope. 



The state of the finances continues to be satisfactory ; the sum 

 of £i, 1 8s. 4d. remains in the hands of the Treasurer, after 

 expending £2% i6s. 3d. in the purchase of new books and 

 periodicals. The number of members has slightly increased during 

 the year. It is also gratifying to the Committee to report that 

 the Society is becoming much more widely known ; the number of 

 similar Societies in correspondence with it, both in this country 

 and America, has considerably increased. 



Presentations of the following Books have been received by 

 the Society during the year, viz. :— On the Comparative Micro- 

 scopic Structure of Ancient and Modern Volcanic Rocks, and on
