B. H. Cooper. Mr. Kobarts having explained the investigations 
carried on in 1882 by the Essex Field Club, the party continued 
their walk through Little and Great Monk Woods to the 
Romano-British Camp at Ambresbury Banks, commonly known 
as Boadicea’s Camp, returning towards Chingford by the King’s 
Oak and High Beach. The walk having been rather long for 
the time available, the party drove from High Beach to Ching- 
ford Station, through Fairmead, past Connaught Water and 
Queen EHlizabeth’s Lodge. Owing to the long-continued drought, 
the expedition as regards fungi was a failure, very few specimens 
being secured, particulars of which have been furnished by Dr. 
Franklin Parsons as follows; but the beautiful weather made 
the walk a most enjoyable one. List of fungi found on this 
occasion :—Russula emetica, R. nigricans, R. lutea, Lactarius 
rufus, Agaricus phalloides, A. spadiceus, Hydnum repandum, 
Phallus impudicus, Polyporus versicolor, Boletus scaber, Sclero- 
derma vulgare. 
January 15th, 1896.—A party of twenty-one, under the guid- 
ance of Mr. Baldock, paid a visit to Brin’s Oxygen Factory at 
Westminster, and were shown over the works by Mr. Murray, 
the manager. The process for obtaining oxygen is based upon 
the property possessed by barium monoxide of absorbing another 
atom of oxygen from the atmosphere when submitted to a high 
temperature (in practice, 1350° Fahr. is found most convenient). 
The additional atom is again given off when pressure is reduced, 
barium monoxide being reformed, and the process can be repeated 
almost indefinitely. The barium is placed in a series of retorts 
arranged in a furnace heated by carbon monoxide, and a current 
of purified air passed through these under a pressure of about 
ten pounds to the inch, oxygen is absorbed, the nitrogen passing 
away into the air. The pressure is then reduced, and as the 
oxygen is given off it is conveyed to a holder, and is then ready 
to be-compressed by a pump into cylinders of various sizes. 
The process of testing the cylinders was also explained by 
Mr. Murray.

February 19th.—At this meeting the Report of the Meteoro- 
logical Sub-Committee, prepared by Mr. Francis Campbell-Bayard 
the Hon. Sec., was presented and read. The full report was 
printed in the last number of our ‘Transactions’ (Trans., 
Art. 120). It was stated that the number of stations had been 
increased by fourteen, thus making the returns more and more 
representative. The number of stations of which the records 
haye been tabulated was sixty-six, and the observers number 
fifty-four, as against fifty-three in the last Report. Although it
