number of green bodies from to 4 - < ^ g of an inch in diameter. 
Its multiplication was very simple. The cells became elongated and 
depressed in the middle, a septum dividing them into two; this was 
crossed at a right angle by another septum dividing them into three 
or four cells. Its mode of reproduction showed it to have been 
probably an aquatic plant. Its food was taken from rain water, and 
sunlight was necessary for its development. The motile and immotile 
forms were spoken of as bearing a strong resemblance to some low 
forms of animal life. The paper concluded by referring to the profit 
and pleasure of tracing out the life history of any common form of 
alga or fungus.—July 30th. Mr. J. Madison exhibited a specimen of 
Helix aspersa var. tenuis, from Guernsey; under the microscope, Mr. 
J. W. Neville, parasite of Limax flavus ; Mr. Rodgers, Volvox globator, 
from a tank in which he had kept it for three years.—August 13th. 
Mr. H. Hawkes exhibited the following fungi from Hamstead Park :— 
Panus conchatu*, Polyporus squamosus, Diachcea elegans, Graterium 
minutum, and Diderma vernicosum; Mr. J. Madison, Helix aspersa var. 
minor and //. virgata var. subalbida and albicans; Mr. J. Collins, 
Spircea Jilipendula, Gritlimum maritimum and other plants from Somerset¬ 
shire ; under the microscopes, Mr. W. Dunn, Melicerta ringens; Mr. 
Collins, Ceramium acanthonotum. 
DUDLEY GEOLOGICAL SOCIETY AND FIELD CLUB.— 
This Society held a Field Meeting on Wednesday, the 22nd inst., at 
Ankerdine Hill, Knightwick, on the Worcester and Bromyard line of 
railway. This hill, though not at all lofty, is considered the most 
picturesque hill in Worcestershire, commanding very extensive views 
in every direction, and as the day was very clear, the party were much 
delighted with the prospect, which included the Malverns, which show 
up grandly in their massiveness from this point; the Abberley range, 
the Titterstone and Brown Clees, Clent and the Lickey, Bredon and 
the Cotteswolds, with a distant view of the Sugar Loaf and Black 
Mountain. The hill is mainly composed of Upper Llandovery beds, 
which, being on the axial line of disturbance of the Malvern and 
Abberley Hills, are much dislocated and faulted against rocks of 
several later formations. Some of the bands are very fossiliferous, 
and contain innumerable casts of Atrypa hemispherica, and the delicate 
worm-tube, Tentaculitcs annulatus; but as the matrix is a rather coarse 
and loose sandstone, the specimens are very unsatisfactory. The 
botany of the neighbourhood is especially rich and varied, and, among 
the more rare species of plants met with, the following were 
determined by the Rev. J. H. Thompson and Dr. Fraser: —Vicia 
gracilis, Hieracium murorum, Hypericum Androscemum, Erythrcea 
Gentaurium var. flare albo, Cardamine impatiens, Geranium pusillum, 
Geranium dissectum, Conium viaculatum, Malachium aquaticum, Sison 
Amomum, Origanum vulgare, Potentilla argentea, Matricaria Chamomilla, 
Pimpinella Saxifraga, Rhamnus catharticus, Cerasus austera, Poa nemor- 
alis, Brachypodium sylvaticum. In the course of the day the President, 
Mr. Horace Pearce, F.L.S., F.G.S., exhibited the following rare plants:— 
Verbascum Lychnitis, Nasturtium amphibium, and Ly thrum Salic aria, 
from Whittington; Sedum Rhodiola, in fruit, from Snowdon ; Erica 
vagans, from The Lizard, Cornwall; Erodium maritimum, from Habberley 
Valley ; and Tragopogon pratensis, from lane, near Stourbridge. 
Mr. W. Madeley also exhibited a fine flint celt (Palaeolithic), and two 
scrapers from river, Maidstone, of which he guaranteed the genuineness. 
The Society will hold a half-day meeting at Pouk Hill, Walsall, on 
Saturday, the 1st September, for the purpose of examining the Trap
