as to the fast application of the gas, as an 

 economical substitute for oils and tallo\v, 

 in the production of light for public and 

 private purposes. This is what I have 

 claimed, and for which I have been 

 -honoured with the Royal Society's gold 

 medal ; disgraced, I should rather say, 

 if I have no claim to the merit thus 

 imputed to me. 



But how has this committee stripped 

 me of my claim ? Did the German 

 DiUer, by his philosophical fire-works at 

 the Lyceum, by " his large lustres of 

 little flames in the centre of the room," 

 exhibited for the amusement of the 

 curious and ignorant, make the ap- 

 plication of gas to purposes of public 

 and private utility ; guarding, as I 

 am informed he did, at the same 

 time, his mode of proceeding, wjth all 

 the mercenary caution of a juggler ? 

 Can the Gas-Committee set this puppet- 

 fti Parliament.

1809. 



An account of the application oftfie G \sfrom Coal 

 to economical purposes, Inj Mr. WILLIAM 

 MURDOCK, read before the Royal Society, on the 

 25th February, 1808, _ and printed in the Phi- 

 losophical Transactions for that year. 



The facts and results intended to be communicated in 

 tlus paper, are founded upon observations made during 

 *he present winter at the Cotton Manufactory of Messrs. 

 Philips and Lee at Manchester, where the light obtained 

 by "the combustion of the Gas from Coal is used upon a very 

 large scale ; the Apparatus for its production and appli- 

 cation having been prepared by me at the Works of Messrs. 

 Boulton, Watt, and Co. at Soho. 



The whole of the rooms of this Cotton Mill which is I 

 "believe, the most extensive in the united Kingdom, as well 

 as its counting houses and store rooms; and the adjacent 

 dwelling house of Mr. Lee, are lighted with' the Gasl'rom 

 Coal. The total quantity of light used during the hours 

 of burning, has been asstfrtained by a comparison of sha- 

 dows, to be about equal to the light which 2500 moultf 

 Candles, of six in the pound, would give; each of the 

 candles with which the comparison was made, consuming 

 at the rate of T * 5 of an ounce, (175 grs.) of tallow per 

 hour. 



The quantity of light is necessarily liable to some vari- 

 ation, from the difficulty of adjusting all the flames so as 

 to be perfectly equal at all times. But the admirable pre- 

 cision and exactness with which the business of this Mill 

 is conducted, afforded as excellent an opportunity o{ 

 making the comparative trials 1 had in view, ;is is perhaps 

 likely to be ever obtained ir general practice. And tin' 1 " 

 experiments being made upon so large a scale, and for a 

 considerable period of time, may I think be assumed <js a 

 sufficiently accurate standard for determining ihe udvan- 



Nos. 12294-7 (page 612).
