REPORTS OF SOCIETIES. 
Mr. C. P. Neville exhibited marine shells from Sydney; Mr. J. 
Madison, specimens of Bulimus detritus from Switzerland; Mr. Camm, 
Trichina spiralis in rat’s tongue. Then followed a paper on “ A Con- 
chological Ramble in South Wales.” The ramble was from 
Caermarthen up the country to the lakes in the Black Mountains, 
on the border of Brecknockshire, to search one of the lakes, Llyn-van- 
fach, for specimens of Limncea pereyra var. Burnetti , said to be found 
there. The route was described and the various shells met with on 
the way, and the position and scenery of the lakes and their 
surroundings with the shells found in them. The journey was a 
successful one and yielded specimens of the shell sought. The return 
was made by way of Swansea. The shells collected in the ramble 
were exhibited.—March 5th. Mr. Bennett showed differently coloured 
sands from Alum Bay, Isle of Wight. Under the microscope, Mr. 
Camm, Garchesiumpolypinuin ; Mr. J. W. Neville exhibited foraminifera 
from Jersey, and called attention to the resemblance they bore in form 
and texture to those derived from the Cambridgeshire silt.—March 
12th. A lime-light lantern exhibition of natural history objects. The 
President in the chair. The President showed a series of photographs 
of rock sections, pointing out the various inclusions in rocks and how 
such inclusions arose; Mr. J. W. Neville, a series of illustrations of 
Rhizopods, Rotifers, and Polvzoa; Mr. O. Hutchinson, photo-micro¬ 
graphs of rocks, sections, and diatomaceae ; Mr. W. Tylar, rural scenery, 
hedgerows, frost effects, etc.; Mr. Delicate, photographs of the rocks 
and caverns of the Wren’s Nest; Mr. C. Pumplirey, photographs of 
flowers ; Mr. J. Edmonds, photographs of animal and vegetable tissues, 
illustrations of pond life, and some miscellaneous views.—March 19th. 
Subject: “ Object Mounting and Section Cutting.” Mr. Delicate gave 
some useful hints on the mounting of animal and vegetable tissues in 
Deane’s gelatine. Mr. H. Hawkes described the usefulness of 
glycerine as a mounting medium, and the class of objects best adapted 
for it. The chief difficulty in its use was in the ringing, but this had 
been overcome by the use of gum damar dissolved in benzoline, 
instead of the usual gold size. Mr. J. W. Neville described the 
preparation and mounting of insects in balsam. A collection of 
slides was exhibited to illustrate each process.—March 26th. Mr J. 
Edmonds gave a lecture on “ Photo-Micrographv Simplified.” The 
speaker said his object was not so much to show the best way of 
accomplishing the end in view as the simplest and least expensive one. 
Though the visual and actinic rays of light did not focus exactly on 
the same plane, jyet in practice he had found an ordinary microscopic 
object glass capable of producing good pictures. The camera was 
dispensed with, and the image formed bv an object glass fixed in the 
microscope stand thrown on a mo'veable screen. The simplicity of the 
arrangement was much admired. During the evening a negative was 
taken that gave every satisfaction, and showed how readily a micro- 
scopist could produce permanent records of his studies.—April 9th. 
Mr. J. W. Neville exhibited specimens of Trinucleus concentricus, a 
trilobite from the Mid-Bala shales; Mr. Deakin, a collection of 
fossils from the fiuvio-marine beds of the Eocene formation. Isle of 
Wight; Mr. Hopkins, specimens of Helix aspersa, showing umbilicus ; 
Mr. J. Collins, specimens of Ostrea expansa and other fossils from 
Portland ; Mr. Hawkes, a collection of marine algae, including specimens 
of Ptilota eleyans, with tetraspores and Sphcerococcus coronopifolius. 
Under the microscopes Mr. Hawkes showed a series of preparations of 
algae ; Mr. J. Collins, Ceramium nodosum.
