John George Children to Faraday   9 May 1834

My dear Faraday

Mr. Watkins fears that his charcoal is not so good for the voltaic light, tomorrow night as he could wish. Pray have the goodness to have some prepared and send it to Mr. Watkins as soon as you can, who will have it filed up into a convenient form. I have always found box-wood the best for the purpose[.]

Ever yours | most truly | J.G. Children

Charing <cross> | May 9th 1834.
