 ,, Charles Baker. Nelson's New Low-Power Condenser. 



Your Committee wish to thank the authors and exhibitors 

 for these interesting communications and exhibits. It will be 

 seen that there has been no falling-off in either the quality or 

 quantity of papers submitted to the Club. 



There were eleven excursions during the season, and all were 

 well attended, except on one occasion when the weather was 

 very bad ; the record number of fifty-three members met to visit 

 the Royal Botanic Gardens. The total attendances for all ex- 

 cursions was 235, which is also a record for any one year, and the 

 average of 21*4 per excursion has only been exceeded once before. 



The collecting, though not including anything new, was always 

 satisfactory. 



The thanks of the Club are due to the Secretary of the Royal 

 Botanic Gardens and to the Metropolitan Water Board for 

 permission to visit their enclosures ; also to the Port of London 

 Authority and Mr. Carlyle, who so kindly entertained the 

 members at tea after their visit to the Surrey Commercial Docks. 

 Later in the year a party of members gave an exhibition of 

 Pond Life at the Dock Club and Institute, on which occasion 

 Messrs. Soar, Offord and Wilson gave short lectures with lantern 

 illustrations. 



The Hon. Librarian and his assistant have expended a con- 

 siderable amount of time and labour upon the classification and 

 arrangement of the Club's books, and great progress has been 

 made with the preparation of the new catalogue. The amount 

 allotted to the cost of binding has been exceeded by 5, and 

 repairs and cases for loose parts have cost about <11. The 

 question of the elimination of periodicals containing nothing of 

 particular interest to microscopists is before your Committee ; 

 the limitation of space for housing the Club's books being a 

 difficulty that it has to meet. The Library has been used in 

 1912 as much as in previous years, but the cost of housing 

 relatively to the use that is made of the books presents quite 

 a serious problem for consideration by your Committee. 



During the year under review the following volumes have been 

 added :
