but for use in narrow-necked bottles or test-tubes, or in other 

 instances where the scissors could not be used. 



The construction of the forcep scissors may be readily under- 

 stood from the following short description as given by the 

 inventor. 



The edge of one blade of the scissors is ground at right 

 angles to the cutting surface (Fig. 1). At the point p on the 

 other blade is firmly fixed, at the broad end only, a steel 

 spring made square at the farther end. This spring projects 

 beyond the cutting edge of the blade when the scissors are 

 open. The object shown (sectional diagram) is first held as the 

 scissors are closing, and is cut off when they are finally closed,, 

 being retained until released by the reopening of the blades. 



Mr. C. F. Rousselet, F.P.M.S., said he thought the pieces

 forceps — also designed to hold a cut piece of weed in a somewhat 

 similar manner. 



Mr. H. Taverner, F.R.M.S., exhibited a number of stereo- 

 photomicrographs of water-mites done by the Sanger- Shepherd 

 three-colour transparency process in the manner he had de- 

 scribed at a former meeting of the Club. The photographs 

 now before the meeting were all taken with a l|-in. objective,, 

 with a diaphragm behind having a circular aperture of 2 mm. 

 A separation between centres of 2 mm. was employed to obtain 

 the stereoscopic pair. 



The Hon. Secretary said he regretted to have to announce 

 the death, on September 27th last, of Professor Chas. Stewart, 

 LL.D. Aberdeen, F.R.S., etc. Professor Stewart joined the
