BIRMINGHAM NATURAL HISTORY AND MICROSCOPICAL 
SOCIETY.— Biological Section. June 10th. Mr. W. R. Hughes in 
the chair. Mr. J. W. Gray, C.E., was proposed for membership. Mr. 
W. H. Wilkinson exhibited several lichens collected on the Broadway 
excursion, viz.:— Parmelia olivacea, P. saxatilis , Physcia pulverulenta , 
P. ciliaris, Gladonia pyxidata , Placodium murorum, and Lecanora 
subfusca. Mr. W. R. Hughes exhibited, also from Broadway, Polygala 
vulgaris , showing various shades of colour from white, pink, pale blue, 
dark blue, to purple; also Listera ovata, Orchis maculata, and Briza 
media. Mr. E. H. Wagstaff exhibited part of bottom of ship’s timber 
pierced by the Teredo worm, from Weymouth Bay. Mr. Colbran J. 
Wainwright exhibited Notodonta camelina and Ptilodontis palpina, in 
state of rest, resembling dead leaves, &c.; Volucella bovibyIans, mimick¬ 
ing Bornbus lapidarius and uiuscoruvi, in whose nests its eggs are laid, 
and whose larvae are the prey of the larvae of Volucella.— Geological 
Section. June 17th. Mr. T. H. Waller, B.A., B.Sc., in the chair. 
Mr. J. W. Gray, C.E., of Bristol Road, was unanimously elected a 
member. Mr. Hughes exhibited specimens of Diorite, Litho- 
strotion basaltiforme , and Rhyolite, from the Wrekin. Mr. Waller 
exhibited a section of glassy rock with perlitic cracks, also with 
spherulites through which the streams of microliths pass uninterrup¬ 
tedly. Mr. J. Edmonds exhibited a pebble of carboniferous sandstone 
with calamites. Dr. Chas. Callaway, F.G.S., read his paper on the 
“Unconformity between the Uriconian and Cambrian Rocks of 
Shropshire.” A hearty vote of thanks to Dr. Callaway was proposed 
by the Chairman, seconded by Professor Lapworth, and carried 
unanimously. 
BIRMINGHAM MICROSCOPISTS’ AND NATURALISTS’ 
UNION.—May 19th. Mr. Wagstaff exhibited apart of a ship’s bottom 
filled with perforations of Teredo navalis, also a polished specimen of 
Brazilian agate; Mr. J. Madison, a case of Limnaeidae, including all 
the genera and species found in Britain, except Limncea involuta ; Mr. 
P. T. Deakin, a specimen of Loligo vulgaris ; Mr. H. Hawkes, a collec¬ 
tion of Helix nemoralis and H. hortensis, from Perry Barr, showing a 
great variety of markings in so small an area; Mr. Linton, a Death’s- 
head Moth, Acherontia atropos, taken at Smallheath.—June 2nd. Mr. 
H. Hawkes exhibited a collection of plants from Portland, including 
specimens of lungwort, Pulmonaria officinalis, also a collection of 
seaweeds from the same district; Mr. J. W. Neville, a sea-urchin, 
Echiuocardium pinnatifidum, from Scilly Isles; Mr. G. Corbett gave a 
description of a geological visit to the quarries of Ludlow, and spoke 
of the “ bone bed” as the deposit in which the first traces of fish 
remains are found : a collection of fossils from the district was shown; 
Mr. J. Collins showed pond snails, all of which were covered with a 
pretty alga, Chcetophora elegans ; Mr. White, fossils of Trigonocarpum 
ovatum in coal measure shale ; Mr. H. Hawkes, under the microscope, 
slides of the rarer algae in fruit.—June 9th. Mr. Deakin showed an 
unusual form of Anodonta cygnea from Cofton; Mr. G. H. Corbet, 
teeth of shark, Otodus appendiculatus, from Cambridge Greensand. 
Mr. J. W. Neville showed Volvox globator, and gave an account of some 
experiments he had made in transplanting microscopic organisms into 
convenient ponds. The attempt had been mainly successful, one pond 
yielding a plentiful supply of Volvox globator and Melicerta ringens 
where they had not previously been found. Mr. Thompson then read
