Engines." For many years Mr. West held the post of Lecturer on 
Chemistry in the Leeds School of Medicine. 
Professor Daubeny, F.R.S., President of the Chemical Society, 
thus mentioned Mr. West in the obituary notice of deceased Fellows 
of that Society, which he laid before the Annual Meeting in 1852. 
After naming many circumstances already detailed in the present 
notice, he remarked, my own acquaintance with Mr. West dates as 
far back as the period when he formed, with myself, one of that little 
band of promoters or cultivators of science, who, obedient to the 
summons of Sir David Brewster, assembled at York in 1831, and 
whilst there, in spite of the smallness of our numbers (which, however, 
besides the illustrious philosopher, who first projected the meeting, 
included the names of Dalton, of Murchison, of Forbes, and of Sowerby) 
had the boldness to organize the scheme of that great scientific 
association, which next year obtained its full development at Oxford, 
and has since been welcomed in almost every large city of the British 
dominions. 
Mr. West's first paper before the Leeds Philosophical and Literary 
Society was read in 1819, on some Colours for Painting found at 
Pompei, followed in the ensuing ten years by papers on substances 
from which a blue precipitate may be produced by means of heat : — 
On the Atomic Theory. On Iodine and notice of the ignition of 
Charcoal by the Galvanic Battery. On Mental Originality. The 
Twentieth Century, in verse. On the Varieties of Water. 
1830. On the Decline of the Roman Empire, as related by Gibbon.

with Memorandum of Experiments.
