detail several specimens of ‘‘ Brass and Glass,” some of which he commended 
to the notice of the meeting, whilst of others he remarked, ‘‘the less said, the 
better.” Amongst the former were Tolles’s microscope, with vertical disc for 
the lateral rotation of the sub-stage with two stages, of novel construction ; 
Ross’s new mechanical stage; Crouch’s student’s microscope, with approximately 
frictionless, fine adjustment ; Parkes’ child’s portable microscope, &c. &c. 
At its conclusion a cordial vote of thanks was accorded to Mr. Mayall, and 
the meeting terminated with the usual conversazione. 
MANCHESTER CRYPTOGAMIC SOCIETY.—Monthly meeting, March 
21st, Dr. Carrington, F.R.S.E., in the chair. The principal part of the evening 
was devoted to the subject of Ferns, Mr, Foster having brought a very large 
series of dried ferns, beautifully mounted. The greater number were abnormal 
forms of British species, and the extreme variations were a source of interest to 
those who took a delight in this class of cryptogams. A collection of the 
ferns of Madeira, which had lately been presented to the Free Reference 
Library by the executors of the late John Windsor, F.L.S., was partially 
examined by those present. 
The hon. secretary (Mr. T. Rogers) called the attention of the members to a 
series of microscopic slides which he had brought, showing the prothalli of 
ferns in various stages of development ; some showing the sperm cells, and 
others the perfected young plants. 
Two slides showed the germination of the spores of Hymenophyllum while 
still in situ in their bi-labial indusium on the frond. 
Other slides showed the germination of young ferns direct from the spore 
receptacles on the veinlets of the pennules Adzantum Capillus-veneris. In some 
cases these could be seen under the perfected indusium, whilst in others the in- 
dusium was imperfect and rudimentary. 
Mr. W. H. Pearson exhibited specimens and drawings of a hepatic new to 
Britain, /wngermannia Juratzkana (Limpricht), which he had detected in a 
collection made by Mr. West, of Bradford, when on Ben Lawers last August. 
Mr. Pearson also read a translation of a paper by G. Limpricht on Gymnomz- 
trium adustum, in which he clearly establishes the fact of a true Gymnomitrium 
adustum (Neas). He therefore now alters the name of Sarcoscyphus adustus 
(Spruce) to Sarcoscyphus Sprucez (Limpricht). Specimens and drawings of the 
twa species were afterwards shown. 
Mr. Pearson exhibited specimens of new Radula commutata (Gottsche) 
which had been collected by C. J. Wild, in the same locality as previously 
mentioned at the last meeting. 
Mr. Champs, Mr. Dawson, and Mr. Stanley were elected members of the 
Society. 
MANCHESTER MICROSCOPICAL SOCIETY.—The following list of 
objects exhibited at the Annual Soirée was crowded out of our last issue ; we 
have much pleasure in introducing it here, as it may serve other Societies as a 
guide what to exhibit on similar occasions :—
