John Frederic Daniell to Faraday   30 September 1824

West Humble | Dorking | 30th Sept 1824

My dear Sir,

I shall be very much obliged to you, at your leisure, to send me a few lines to this place to inform me of the progress of my experiment with the gases. If you should find upon opening one of the unguarded portions of hydrogen that no mixture of common air has taken place it may be as well to leave the others some time longer but on the contrary supposition I shall be obliged to you to examine them all.

Excuse the trouble I am giving you & believe me to remain | Yours faithfully | J.F. Daniell

Address: To | Mr. Faraday | Royal Institution
