inked, and gently lowered on to the slide. He had found this 

 method quite satisfactory. 



Mr. James Grundy read a paper communicated by Mr. E. M. 

 Nelson on " The Measurement of the Initial Magnifying Powers 

 of Objectives." Mr. Grundy added a few notes in amplification 

 and explanation of some points in Mr. Nelson's paper, which he 

 illustrated with blackboard diagrams. 



A vote of thanks to Mr. Grundy was carried unanimously. 



At the 494th ordinary meeting of the Club, held on December

A letter was read from the Poyal Microscopical Society 

 enclosing a copy of a resolution passed by their Council, thanking 

 the members of the Q.M.C. who exhibited at their Conversazione 

 on November 19th. 



Mr. B. M. Draper read a paper on a new live box for the 

 exhibition of flies and other large objects under low powers of the 

 microscope the article itself being exhibited in the room under a 

 Greenhough binocular. 



Mr. B. M. Draper also read a paper describing a new stop for 

 obtaining dark-ground illumination with the Greenhough 

 binocular the subject being illustrated by the exhibition of the 

 stop and by a diagram upon the blackboard. 



The Chairman thought the live box well adapted for showing 

 large objects, and inquired if any means were adopted for con- 

 fining the insects or controlling their movements whilst under 

 observation. 



Mr. Draper said there was no other means of controlling the 

 movement of the objects except by the use of a small cell, but 

 the power used being a low one, the whole cell was generally in 

 the field at the same time ; and in answer to a question by 

 Mr. Rousselet, he said that the cover of the cell was only held 

 down by its own weight, but it was prevented from slipping 

 sideways by the upright pins mentioned in the paper.
