I shall forward my lanterns and lamps to you in a few days. They are absolutely safe; and if the miners have any more explosions from their light, it will be their own fault.
You will find, when you see my construction, that the principles as well as the execution are entirely new.
You will find in the second sheet of my paper, which I hope to be able to send to-morrow, the principles of security, and its limits unfolded.
I am, my dear Sir, very sincerely yours,
H. Davy.
TO THE SAME.
London, January 1, 1816.
MY DEAR SIR,
I fear you will have accused me of procrastination in delaying to send you my papers and my lamps.
