The Instruments and Apparatus are in excellent condition. 



During the year the Society has received the following donations: — 



Lady Flower : — An old Microscope, by Hugh Powell, with accessories. 

 Mrs. Hebb : — Microscope, by Baker, with Polariscope and other 



accessories, which had been in constant use by the late Dr. Hebb.

In connexion with the British Science Guilds' Exhibition of Scientific 

 Products at King's College, the Society exhibited a number of instruments 

 to illustrate the Evolution of the British Microscope, and a special report 

 on this subject appears in the Journal. 



CABINET. 



During the year the Slides Cabinet has been thoroughly overhauled 

 and reclassified, and a full report has been presented, which has appeared 

 in the Journal. The Council has expressed its appreciation of the 

 enthusiastic exertions of the Sub-Committee, consisting of Mr. A. 

 Earland and Mr. E. J. Sheppard, which has undertaken this work so 

 successfully, and trusts that the Fellows of the Society will now 

 co-operate in providing slides for those sections which are at present 

 inadequately represented. The Cabinet will be available for the use of 

 Fellows in the course of a few months, on the completion of the Card 

 Index. 



During the year the Council has received from Dr. Urban Pritchard 

 a valuable addition to the Cabinet, in the shape of 100 special Diatom 

 Slides. 



The Wallich Collection, consisting of 995 Diatom and other Slides, 

 together with a series of descriptive note-books and drawings illustrating 

 the Collection, has been presented by the Society to the Trustees of the 

 British Museum. 



MEETINGS. 



Notwithstanding the abnormal conditions under which the work of 

 the Society has been carried on, the meetings have been held as usual, the 

 attendance of Fellows and Visitors has been maintained, and the papers 

 read have been well up to the high standard set by the Society. 



The Biological Section, which meets on the first Wednesday of each 

 month, has had a most successful programme of events, which has 

 included special visits to the liondon School of Medicine for Women ; 

 the John Innes Horticultural Institute, Merton ; King's College 

 Laboratories. 



The thanks of the Society are due to Mr. J. Wilson for his continued 

 energy and activity as Honorary Secretary of this Section.
