Note 44 — Chapter VI

The accuracy of the above statement having been called in question, it is proper to state that the facts as set forth were verbally communicated to the author in the first place by Robert Stephenson, to whom the chapter was afterward read in MS. in the presence of Mr. Sopwith, F.R.S., and received his entire approval. But at the time at which Mr. Stephenson communicated the verbal information, he also handed a little book with his name written in it, still in the author's possession, saying, "Read that; you will find it all there." This little book contains, among other things, a pamphlet, entitled "Report on the Claims of Mr. George Stephenson relative to the Invention of his Safety-lamp. By the Committee appointed at a Meeting holden in Newcastle, on the 1st of November, 1817. With an Appendix containing the Evidence." Among the witnesses examined were George Stephenson, Nicholas Wood, and John Moodie, and their evidence is given in the pamphlet. Stephenson said that he tried the first lamp "in a part of the mine where the air was highly explosive. Nicholas Wood and John Moodie were his companions when the trial was made. They became frightened when they came within hearing of the blower, and would not go any farther. Mr. Stephenson went alone with the lamp to the mouth of the blower," etc. This evidence was confirmed by John Moodie, who said the air of the place where the experiment was about to be tried was such, that, if a lighted candle had been introduced, an explosion would have taken place that would have been "extremely dangerous." "Told Stephenson it was foul, and hinted at the danger; nevertheless, Stephenson would try the lamp, confiding in its safety. Stephenson took the lamp and went with it into the place in which Moodie had been, and Moodie and Wood, apprehensive of the danger, retired to a greater distance," etc. The accuracy of the other statements made in the text relative to the invention of the safety-lamp is confirmed by the same publication.
