36 THE NORTHERN MICROSCOPIST, 
aaa i a ea 
The thanks of the Society were accorded to the Royal Microscopical Society 
for copies of the proceedings and Journals of their Society, and to Miss Marian 
Ridley for a copy of a recent work she has had published as a ‘‘ Pocket Guide 
to the British Ferns.” Thanks were also accorded to Mr. J. Cash for two copies 
of his moss labels, and to Mr. W. E. A. Axon for a reprint of his paper on 
Tricophyton tonsurans. 
The Secretagy’s reports having been adopted, Captain Cunliffe exhibited two 
old interesting books on Cryptogamic Botany ; one by Hedwig (published ° 
1782), the other by Dillenius (published in London, 1763). In this latter book 
it is interesting to note that one of the habitats given for a plant near Man- 
chester was “On the breaking of Medlock river bank at Lasington Wood, 
between Garrett and Knot Mill, about a mile from Manchester.” 
Mr. W. H. Pearson exhibited specimens of the new hepatics described by 
Dr. Spruce recently in the ‘‘ Revue Bryologique,” as Marsupella Stableri and 
Marsupella divacea, both collected by Mr. George Stabler; specimens of the 
former being presented to the Society’s herbarium by the discoverer. Mr. 
Pearson also exhibited specimens of Gymmnomitrium adustum Nees (verum) new 
to Britain, collected by himself last August in Wales. 
The Hon. Secretary read a few Bryological notes from some correspondence 
which Dr. J. B. Wood had kindly placed at his disposal. One of the notes 
referred to specimens of Campylopus paradoxus of Wilson, which had been 
collected some few years ago in swampy ground on Cader Idris by one of the 
Society’s members (Mr. Percival). Its claims to specific distinction has been 
much disputed, as the name implies ; but Juratzka has recently decided that 
it can only be recognised as a variety of Campylopus flexuosus, to which he 
gives the varietal name ‘‘uliginosa.” ‘Another of the notes referred to the new 
classification of the Harfidium group of LLypnums by Renauld, as published in 
a recent article in the Revue Bryologique. Bryologists in this neighbourhood 
will be surprised to find that he places the well-known LHlypnum exannulatum as 
Aypnum fluitans in his classification, and that he considers that certain 
monoicous species appear at times dioicous. 
The following correction has been sent us.—[ED.] 
S1r,—In your last issue I see it is stated by Captain Cunliffe, who presided 
at the last meeting of the Manchester Cryptogamic Society, that he had found 
the rare Wetssta mucronata near his house at Handforth. — He also stated that 
the above moss was an addition to the district of the Manchester flora. As 
the latter statement is certainly erroneous, I think it ought not to pass un- 
corrected. In Buxton’s Guide to the Plants round Manchester, published in 
1859, I find the following record of its discovery in the district :— “ W. 
mucronata, Fallowfields, Park side, W. Wilson, Esq.” I also find the same 
locality repeated by the late lamented Mr. Hunt, in his List of mosses occurring 
in the neighbourhood of Manchester, in the report of the Manchester Field 
Naturalists’ Society for 1863. On referring to my Herbarium I also find that 
I and Roger Scholefield found the same moss in Hattersley, near Mottram, 
Cheshire, April, 1868. It is interesting to notice that Gymnostomum squar- 
vosum, another rare species, is associated with W. mucronata in the three 
localities mentioned above.

MANCHESTER FIELD NATURALISTS’ SOCIETY.—At the Dec. 
meeting of this Society a paper was read by Mr. W. Thomson, Analytical 
Chemist, of Princess-street, upon “ Minute Forms of Vegetation.” The reader 
brought before the notice of the members the fact that the sporules of the 
minute forms of vegetation of which he had to speak were to be found in the 
atmosphere, though they could only be discerned by the naked eye whena 
beam of sunshine entered into aroom. The amount of work which those
