Proceedings. Cxxili 
million cubic feet of gas, and the largest out of London, was 
much admired. Numerous fossil oysters and other shells (Me- 
lania and Cyrena) belonging to the Woolwich Beds, similar to 
those found at Park Hill, were obtained from the earth excavated 
when making the reservoir for the gasometer. After a hearty 
vote of thanks to Mr. Helps for a most interesting and instructive 
evening, and for his hospitality, the party separated. 
September 15th.—This being the first meeting of the season, 
there was no regular paper, but the evening was devoted to 
the exhibition and description of objects obtained during the 
vacation. ‘ 
Mr. Douglas exhibited some beautiful specimens of galena, 
iron pyrites, and calcite, and described some chert containing 
radiolaria from the southern uplands of Scotland (Trans., 
Art. 131). This chert, formerly supposed to be of inorganic 
origin, was proved a few years ago by our member, Dr. Hinde, 
to be made up almost entirely of these protozoa. 
Mr. Waddon Martyn exhibited some nodules of a ferruginous 
mineral obtained in the north of Cornwall. The nodules vary 
very much in size and are very abundant, constantly weathering 
out of the cliff face. 
Mr. Robarts exhibited a larva of the goat moth and a number 
of flint implements: from Cisbury. Mr. Lovett stated that 
Cisbury was one of the places where these implements were 
roughly blocked out to be sent somewhere else to be finished off. 
Mr. C. Hehner exhibited water stones from Chili. These 
consist of agate containing water and a bubble of carbon dioxide. 
Similar stones are found in Victoria. Some calculi consisting 
of ammonio-magnesian phosphate from the stomach of a horse 
were also exhibited by Mr. Hehner. 
Dr. Parsons exhibited a large series of fungi, including a 
mushroom one foot in diameter. Owing to the wet season, 
fungi had been remarkably abundant during the past year. Dr. 
Parsons stated that four and a half inches of rain had fallen 
since the first of the month. 
Mr. Mennell showed an egg of the rock ptarmigan taken by 
him in the Val de Bagne. 
Mr. Lovett exhibited specimens of prism powder-and cordite 
Lora on the recent visit of the Club to the Chilworth powder 
works. 
A specimen of an oyster in a silicified condition from Norfolk 
was exhibited by Mr. G. W. Moore. : 
The President exhibited a series of Silurian fossils obtained 
by him in Shropshire, consisting of corals, trilobites, brachiopods, 
crinoids, and molluscs of various species.
