66 FIFTY-THIRD ANNUAL REPORT. 



As for several years past, there have been no exhibits of new 

 apparatus by opticians, owing to their energies being mono- 

 polised for government purposes. In this connection, however^ 

 mention may be made of a number of pieces of apparatus, 

 thought out and made by our member, Mr. W. R. Traviss, and 

 exhibited and described at the meetings, often giving promise 

 of great usefulness to the working microscopist. 



The more important papers read during 1918 are as follows :
