more than last year, and he considered the financial position of 

 the Club very satisfactory. 



A special vote of thanks was accorded to the Editor of the 

 English Mechanic for his courtesy in publishing lengthy reports of 

 the meetings of the Club in the issue of the week following. The 

 reports are much appreciated by members in general, but especially 

 by our country members, who would otherwise have, to wait for 

 the publication of the half-yearly Journal. 



Mr. H. Morland took the chair, and the annual Presidential 

 Address was then delivered by the retiring President, Dr. E. J. 

 Spitta, F.P.A.S., F.R.M.S., who took for his subject, "The Pho- 

 tography of Very Translucent Diatoms at High Magnifications." 



The usual votes of thanks to the President, auditors, and 

 scrutineers, and committee and officers, were then proposed, 

 seconded, and carried. 



The retiring President then introduced Professor E. A. Minchin, 

 the new President, to the meeting. 



Professor Minchin made a modest acknowledgment of the 

 honour which he said the Club had paid him, and, while not 

 claiming the title of expert on the microscope itself, hoped that he 

 knew a little more about the use of the instrument than the man 

 who complained of the performance of his oil-immersion objective, 

 and was found to have the notion that the eyepiece should be 

 removed and the tube filled up with oil ! He hoped to serve the 

 Club as faithfully as his eminent predecessors. 



Mr. W. Imboden, F.R.M.S., exhibited and described an appa- 

 ratus designed to facilitate the drawing of microscopical low- 

 power objects, the image being projected directly upon a drawing 

 surface, where it can be traced with a pencil in a very convenient 

 and easy way. The apparatus consists in the main of a plate- 

 glass mirror, which is fastened to an extended arm, allowing the 

 distance between .the mirror and ocular, and consequently the 

 magnification, to be modified at will without changing the optical 

 combination. An appliance to exclude light, which might impair 

 the brilliancy of the projected image, is used, and, as the nucleus 

 towards success, adequate illumination (a Nernst lamp was used) 

 must be provided. The device gave very excellent results, and no 

 doubling of the image from the mirror was noticeable. 



Messrs. R. & J. Beck exhibited an immersion paraboloid for the 

 illumination of bacteria, etc., on a dark ground with high powers.
