The account of the author's discovery of ga.s-lighting. ' In February ISOS Murdock read a paper beforo the Royal 

 Society, in which he gave a full account of his investigations, and also of the saving effected by the adoption of gas 

 lighting at Philips & Lee's mill. This paper is the earliest practical essay on the subject. The Rumford gold medal, 

 bearing the inscription 'ex fumo dare lucem', was awarded to Murdock for this paper, which concludes with these 

 words : ' I believe I may, without presuming too much, claim both the first idea of applying and the first actual applica- 

 tion of this gas to economical purposes '. As to the justice of this claim there can be no doubt.'— L*. N. B. 



AN ALL BUT UNIQUE WORK: 



12296 A Letter to a Member of Parliament, in Vindication of his Character and 



Claims ; in Reply to a Recent Publication, by the Committee for Conducting through Parlia- 

 ment a Bill for Incorporating a Gas-Light & Coke Company, 8vo. (pp. 15), sewn (very rare), 

 £3. 10* 1809 



' By this time [ISOS] gas-lighting had fallen into the hands of company promoters, and in 1S09 application was made to 

 incorporate the Gas Light and Coke Company. It was opposed by James Watt the younger on behalf of Boulton & 

 Watt, who feared that their trade might be interfered with ... In answer to a statement put forth by the promoters 

 of the bill, charging Murdock with plagiarism, he issued on 4 May 1809 ' A Letter to a Member of Parliament.' This 

 tract and the paper in the ' Philosophical Transactions' comprise the whole of Murdock's literary efforts. Only two or 

 three copies of the tract seem to hnve survived.'— D. N. B. 



The above copy originally belonged to George Rennie, c.e., f.r.s. 



12297 : Remarks upon the Bill for Incorporating the Gas Light and Coke Company, 



Svo. (pp. 19), seivn {very rare), I8s 1809 



This pamphlet contains the statement, referred to above, in which the Gas Light & Coke Co. charged Murdock with 

 plagiarism. It provoked Murdock's reply in ' A Letter to a Member of Parliament.' The pamphlet was apparently 

 unknown to Murdock's biographer in D. N. B.

' Under the date of 20 Jan. he said ' Fair, prob. lowest deg. of winter tern.' By a happy chance this proved to be a 

 remarkably cold day, the thermometer at sunrise standing at 4° below zero. This circumstance raised his celebrijy to a 

 preat height as a weather prophet, and the shop of his publishers was besieged with customers, while the winter of 1S37-8 

 became known as Murphy's winter. The 1838 almanac ran through 45 editions, and the prophet made £3,000.'— X>. N. B.
