'- \ late Lord Lister. 



Referring to the donations. Dr. Eyre said that the bust of the late 

 Joseph Jackson Lister had been placed in the Society's rooms ; and, 

 further, the Royal Microscopical Society had been offered a number of 

 working tools used in the manufacture of lenses, as well as some of the 

 lenses ground by this distinguished microscopist. Such a donation would 

 prove of considerable interest to the Society ; the Council had therefore 

 delegated Mr. Rousselet to inspect the apparatus, and to secure as much 

 of it as the Executors would permit. 



A special vote of thanks was accorded to Lord Lister's Executors for 

 their interesting and valuable donations. 



Mr. J. W. Ogilvy exhibited two instruments made by Messrs. Leitz : 

 1. An Improved Greenhough Stereoscopic Binocular Microscope, having 

 large working space on stage and a joint for inclination to an angle 

 of 90"^. 2. A Double Ocular (possessing an adjustable pointer) attach- 

 able to the Microscope for demonstration and teaching purposes. 



Mr. Watson Baker exhibited a new Instantaneous Reflex Micro- 

 graphic Camera, which was both simple and effective. The object was 

 observed until the moment of exposure on a ground-glass screen at the 

 side of the camera. A setting device for " time " exposures was also 

 fitted. 



The President proposed a vote of thanks to Messrs. Ogilvy and 

 Watson Baker for their interesting exhibitions, which was carried with 

 acclamation.
