QUEKETT MICROSCOPICAL CLUB. 351 



Mr. H. F. Angus (H. F. Angus & Co.) showed the Reichert 

 demonstration and comparison eye-piece for comparing the fields 

 from two microscopes in one eye-piece, in which the field is divided 

 laterally, Akehurst's phototropic pond-life trap, Draper's all-glass 

 live box, the Finlayson revolving disc for the exhibition of a 

 series of opaque objects, Heath's objective-guard, etc. 



Mr. Lees dirties (C. Baker) had on view several Greenhough 

 binocular microscopes, multicolour illumination of crystals, and 

 three forms of the Cheshire apertometer. 



Mr. C. Beck (R. & J. Beck) exhibited the new model high- 

 power binocular, employing a -jVth oil-immersion objective, with 

 a very simple and efficient adjustment for inter-pupillary 

 distance. 



Mr. J. W. Ogilvy (E. Leitz) showed several new short-tube 

 high-power binoculars employing a T Vth oil-immersion objective ; 

 a comparison eye-piece for comparing simultaneously complete 

 fields of two microscopes; and several examples of the Green- 

 hough binocular one especially adapted for metallurgical work. 



Mr. F. W. W. Baker (W. Watson & Sons) exhibited a new 

 model Yan Heurck, with 2| in. movement to the stage, and 

 complete rotation, also a new workshop metallurgical microscope 

 and some twenty microscopes with various objects, including a 

 series of seven illustrating the development of the chick from 

 twenty-four hours to four clays. 



During the evening a lantern lecture was given in the large 

 theatre by Mr. F. W. Watson Baker (Watson & Sons) on " Some 

 Microscopical Hows," and subsequently Mr. C. Lees dirties 

 (C. Baker) gave a lantern demonstration, in the same place, of 

 natural-colour photographs and photomicrographs of miscellaneous 

 and microscopic objects prepared by the Paget process. Both 

 lectures were well attended and much appreciated. 



Of late years the club has not held conversaziones, and during 

 the evening the wish was several times expressed that such 

 gatherings should be more frequent, and certainly that no long 

 interval should elapse between this and the next. (The last 

 conversazione was held nearly seventeen years ago on May 4th, 

 1897 in the smaller Queen's Hall.)
