as to theirs/ application of the gas, as an 

 economical substitute for oils and tallow, 

 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 Rojal Societ}f's gold 

 medal ; disgraced, I should rather sa v, 

 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 

 Diller, 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 infoi-med he did, at the same 

 lime, his mode of proceeding, with all 

 the mercenary caution of a juggler ? 

 Can the Gas-Committee set this puppet-

An account of the application cftf^c Gas from Coal 

 to a'conomical purposes. Inj Mr. VVilliam 

 MuRDOCK, read before the Royal Society, on the 

 9.5th February, ISOS, and printed in the Phi- 

 losophical Transactions Jor that year. 



The facts and results intended to be communicated in 

 tills paper, are founded upon observations mad^ during 

 «^he present winter at the Cotton Manufactory of Messrs. 

 Philips and Lee at Manchester, where the light obtained 

 bylhe 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 ^Vorks 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 roomsi and the adjaccni 

 dwelling house of Mr. Lee, are lighted with the Gas from 

 Coal. The total quantity of light used durmg tlie hours 

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

 dows, to be about equal to the light which 2jOO moulvl 

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

 candles with which the comparison was made, consuming 

 at the rate of /o of an ounce, {115 grs.) of ullow per 

 hour. 



The quantity of light is necessarily liable to some vari- 

 ation, from tlie difficulty of adjusting all the flames so m 

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

 cision and exactness with which the business of this Mill 

 is conducted, afforded as excellent an opportunity ol 

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

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

 experiments being made upon so largfe a scale, ^Ild for jt 

 considerable period of time-, may I think be assuinaed <\s a 

 sufficientlv accurate standard for dctcrminui'' the advan- 



Nos. 12294-7 (paf/e 612). 

 The invention of gas lighting.
