Dr. Scoresby then came forward, and said the four subjects he intended to introduce to the meeting, if he should have time, were—
Some account of the Decomposition of Water into its Constituent Elements by Heat, and vice versa.
Some account of the Tube across the Menai Straits.
Observations on Professor Schonbëin’s Explosive Cotton.
Some notice of Artesian Wells, with the new mode of Boring them, as suggested by Mons. Fauvelle.
The first theory had been advanced by Professor Grove, at the discussions of the Chemical Section for the Advancement of Science, at Southampton, who had contrived an apparatus called the “Euidiometer,” by which he could collect the gases, and make satisfactory experiments upon them. It was asserted by Professor Grove that the same process which would combine gases would also separate them. It was a well-known fact that water was composed of oxygen and hydrogen, from a chemical union of which it can be easily formed. No success had attended any attempt to collect both oxygen and hydrogen into one experiment, without having been absorbed by any other substance. The process introduced by Professor Grove was clearly elucidated by diagrams, and consisted in the introduction of two platina wires into the lower part of a glass tube, hermetically sealed and filled with water, from which the atmospheric air had been expelled by the process of boiling. The wire is then heated in an immense degree by the galvanic current, and the intense heat has the ...
