Faraday to Henry Minchin Noad   c.1854–18551

My dear Sir,

Whilst looking over my papers on induction2, I was reminded of our talk about Harris’s unit jar, and recollected that I had given you a result just the reverse of my old conclusions, and, as I believe, of the truth. I think the jar is a true measure, so long as the circumstances of position, &c., are not altered; for its discharge and the quantity of electricity thus passed on depends on the constant relation of the balls connected with the inner and outer surface coating of each other, and is independent of their joint relation to the machine, battery, &c. ... Perhaps I have not made my view clear, but next time we meet, remind me of the matter3.

Every truly yours, | M. Faraday.
