MANCHESTER CRYPTOGAMIC SOCIETY.—Mr. Thomas Brittain 
presided over the meeting of the Manchester Cryptogamic Society, held on 
Monday, October 17th, and gave a brief account of his recent visit to Cornwall, 
where he met Mr. Ralfs, Mr. Curnow, and Mr. Marquand, an eminent trio of 
Cryptogamic botanists, who reside in the vicinity of Penzance, and with whom 
he made several rambles in the more immediate localities, and who made his 
visit pleasant by social intercourse in the evenings. : 
Mr. Brittain had collected a large number of microscopic fungi and a few 
lichens, and some of these he kindly distributed at the meeting. 
Mr. James Cash had also recently returned from a visit to Scotland and 
exhibited some of his finds, amongst them being Orthothecium rufescens from 
the vicinity of Loch Fyne, Ulota Ludwigii from trees near Inverary, and 
Dicranum Scotianum from Loch Reden in Argyleshire ; these were in excellent 
fruiting condition. 
Mr. W. H. Pearson exhibited Riccia crystallina from Suffolk, and /unger- 
mannia Pearsoni (Spruce), which latter had been collected last June in West- 
moreland by Mr. Stabler, this being the second recorded station for this new 
species. 
Mr. T. Rogers exhibited a number of foreign mosses and hepaticz from the 
collection made by Edward and William Hobson, who were once active 
Manchester botanists and members of the old Banksian Natural History Society. 
The time of the meeting was fully occupied, and very pleasantly spent. 
MANCHESTER MICROSCOPICAL SOCIETY.—The ordinary meeting 
of the Manchester Microscopical Society was held on Tuesday, October 6th, at 
the Mechanics’ Institution, Mr. George E. Davis, F.R.M.S., one of the Vice- 
Presidents, in the chair. There was a large gathering of members. 
M. W. Blackburn read a paper on the Zphemeride, or May-Flies, an abstract 
of which appears in these pages for the present month. The paper, which was 
of considerable length, was illustrated by numerous drawings and some speci- 
mens, mounted for the microscope, prepared by the author. The Chairman 
complimented the reader on the masterly manner in which the subject had been 
treated, and a hearty vote of thanks was accorded him. 
Mr. H. C. Chadwick exhibited the results of a series of attempts to mount 
Luglena viridis as a permanent slide. They were mounted in very shallow 
cells made with brown cement, and had been treated with a one per cent. solu- 
tion of osmic acid, as recommended by Mr. Saville Kent. After being exposed 
to the diffused light in a room for nearly three weeks, the specimens were found 
to be stained by the acid, the original brilliant green colour having almost 
disappeared. 
Mr. Thomas Brittain had sent from Falmouth specimens of Phragmidium 
bulbosum for distribution among the members, and Mr. Doherty distributed a 
quantity of Volvox globator. Mr. Aylward exhibited a convenient microscopic 
mounting cabinet, into which was fitted a mounting microscope, spirit lamp, 
section cutter, turntable, and a set of dissecting instruments. In addition there 
was the usual assortment of varnishes and cements, together with a supply of 
slips and cover glasses. All these were conveniently arranged, so as to be 
ready for use at any time. By simply opening the lid of the cabinet there is a
