MANCHESTER CRYPTOGAMIC SOCIETY.—Feb 2ist, Dr. Carring- 
ton, F.R.S.E., in the chair. After the previous minutes had been confirmed, 
Dr. Carrington wished to correct an error in the description having reference 
to the fertile specimens of Radula Moorei which he brought before the notice of 
the Society at the last meeting. 
Mr. W. H. Pearson exhibited specimens and drawings of Radula commutata 
of Gottsche’s AZ..S..S. ; a species new to Britain. Specimens of this species had 
been collected some time ago by A. Croal, but the specimens then exhibited 
had been collected in July last by G. A. Holt, in the Breadalbane Mountains, 
but had not hitherto been recognised as Radula commutata until a recent exam- 
ination made by himself. 
Specimens of Lefzdozta reptans were referred to in Carrington and Pear- 
son’s Hepatice Britannice Exsiccate (which lay on the table), Dr. Carrington 
pointing out that the particular specimen from Tyn-y-Croes had been recognised 
by Dr. Spence as distinct from Lefzdozia reptans, he having examined speci- 
mens which had been specially sent to him for that purpose, by Mr. Pearson, 
and which he now named Lepidozia Pearsont. 
The examination of a portion of Austin’s collection of American mosses which 
had been brought by Capt. P. G. Cunliffe, occupied the rest of the evening. A 
further examination will be made on a future occasion, 
MANCHESTER MICROSCOPICAL SOCIETY.—The ordinary meeting 
of the Society was held at the Mechanics’ Institution, on Thursday evening, 
March 3rd. There was a good attendance. 
John Boyd, Esq., the president, in opening the business of the meeting, 
congratulated the members on the successful issue of the Soiree. 
Mr. Brittain, one of the vice-presidents, gave a short paper on the lichen 
Verrucaria nitida, The paper was illustrated by large drawings of the 
various organs prepared for the purpose of this paper by the Lecturer. 
Mr. Boyd made a short communication on a parasite from the skin of man, 
Demodex folticulorum ; this was also illustrated by a diagram prepared by 
Mr, Boyd. 
Mr, Miles called attention to a slide of the decolored leaf of an insectiverous 
plant Pinguicula vulgaris, shewing the insect infolded and partially digested. 
Mr. Lofthouse remarked that Lefisma saccharina might be profitably 
studied by beginners in microscopy, especially having regard to the scales of the 
insect, as furnishing capital practice in illumination. 
Mr. Brittain then made a communication with regard to a new portable 
microscope, which, with a good French triplet, could be purchased for three 
guineas. 
Mr. E. Ward exhibited a similar instrument, and, later on, with a Zeiss D 
(one-sixth) attached, shewed up well the striated muscular fibre of the cock- 
roach, 
Mr. J. Brown also brought before the notice of the members a pocket micro- 
scope slightly differing in make from the former, but well adapted for the 
purpose, 
Mr, Mestayer asked for information with regard to the vibrating molecules
