SIR,
I now have the pleasure of sending you a copy of the Resolutions of the general meeting of Coal-owners on the 31st instant, and shall take the liberty of informing you of the future progress of this affair.
Sir Humphry did me the honour yesterday to accompany me through the workings of a coal-pit at Wall's-End, when I had an opportunity of witnessing several interesting experiments on his Safety-lamp; and I have the satisfaction to add, that I believe he has now advanced it to the highest degree of perfection.
I am, respectfully, Sir,
Your humble Servant,
John Buddle.
The satisfactory result of this visit Sir Humphry communicated to Mr. Lambton, now Lord Durham; and I shall take this opportunity to state, that for this as well as for several other letters I shall hereafter have occasion to introduce, I am indebted to that noble Lord, through the kind application of my friend Sir Cuthbert Sharp.
TO J. G. LAMBTON, ESQ. M.P.
Newcastle, September 9, 1816.
MY DEAR SIR,
Since I last had the pleasure of seeing you, I have examined the workings in the Wall's-End collieries by the lamps, and have tried them in various explosive mixtures.
On Sunday, I went with Mr. Buddle to your blower, with the single lamps furnished with small tin reflectors. This simple modification rendered them perfectly safe, even in the furious blow-pipe, and at the same time increased their light. Nothing could be more satisfactory than all the trials.
