300 FIFTY-FIRST ANNUAL REPORT. 



November 2^th. — Mr. D. J. Scourfield : On the Volvocaceae, with 

 reference particularly to a slide of Pleodorina illinoisensis, 

 exhibited by him. 



Your Committee, on behalf of the Club, desires to thank the 

 authors of these communications. There have been no exhibits 

 of new apparatus by the opticians, their energies being almost 

 entirely taken up in meeting the demands of Government require- 

 ments. 



The publication of the Journal, both the April and November 

 numbers, has been somewhat delayed — especially the latter ; 

 this has been chiefly due to difficulties arising from shortage 

 of labour at the printers, and our Hon. Editor deserves the 

 sympathy of members for the extra work and trouble it has 

 entailed. 



The Committee would like to give some expression — in which 

 they are sure the members will join — to their sorrow at the serious 

 and long-continued illness of Mr. C. F. Rousselet, and to their 

 sympathy with him. 



The Librarian reports that the number of books issued to 

 members during the year has been the same as last year, which is 

 encouraging, as 25 per cent, more were taken out during 1915 

 and 1916 than in the two preceding years 1913-14 ; an indication 

 that the members are showing an increasing interest in the Club's 

 valuable collection of books. 



In addition to the twenty-eight books added during 1916, 

 there has been received from Mr. Rousselet a very interesting 

 series of photographs of drawings, and drawings of Rotifera. 



These are being arranged for convenience of reference, and will 

 shortly be available for the use of members.
