2(11' PROCEEDINGS OF I UK SOCIETY, 



MEETING 



Held ok the L7th March, L915, at 20 Hanover Square, \\ .. 

 Mr. D. .J. Scourfield, F.Z.S., Vice-President, i\ the Chair. 



The Minutes of the Meeting of February 17 were read and con- 

 finned, and were signed by the Chairman. 



The Chairman, in announcing the donation of an old Microscope of 

 curious design, said it had been presented by Mr. Sydney C. Akehurst, 

 F.R.M.S., and after a few remarks from Mr. Rousselet in regard to its 

 history, a hearty vote of thanks was accorded the donor. 



In showing the presentation Mr. Rousselet said that this was a \ ery 

 interesting and well-made specimen of the early part of the 19th Century, 

 not yet represented in the Society's collection ; although there was no 

 engraving or clue to indicate the maker, the style and workmanship may 

 well have been that of Gary, who was in the habit of making small 

 stands of various sorts, embodying features of earlier periods. The 

 brass stand was made to incline by a compass joint at the base, and also 

 has a brass clamp for fixing to a table. The focusing arrangement 

 is similar to that used by Benjamin Martin, the screw being clamped 

 to the square stem and the fine screw then moves the stage, which also 

 has a screw movement. The optical part consists of a single lens of low 

 power. 



Mr. Edward J. Sheppard, F.R.M.S., then read a paper on " A New 

 Mitotic Structure Disclosed as the Result of New Technique," which 

 appears in extenso in the Society's Journal. 



The Chairman, in the name of the Society, thanked Mr. Sheppard 

 for his most interesting and instructive paper, and invited discussion 

 thereon by the Fellows present. 



Dr. Hebb pointed out that the words " methyl-blue " had been used 

 several times. Was it certainly methyl-blue, or was it methylene-blue ? 

 because the two stains were very often confused, and they were utterly 

 different in their composition. 



Mr. Sheppard, in reply, said that the stain he had used and described 

 in his paper was methyl-blue as obtained from Griibler in capsuled 

 bottles. It was possible that the previous treatment with iron and 

 permanganate might have some very material action on the stain, but 

 he was unable to speak definitely on this point. He would, however, 

 investi irate the matter further. 



The Chairman called upon Mr. Hopkinson to read a paper by 

 Mr. G. H. Wailes. F.L.S.. entitled "Notes on the Structure of Tests of 

 Fresh-water Rhizopoda." 



Mr. Hopkinson said that he was in some measure responsible for this
