Humphry Davy to Faraday   14 September 1821

Lowther Castle¹ | near Penrith | Sept 14

My dear Mr Faraday

I sent a few days ago my paper on Electricity² to Mr Bulmer³. If it is printed, I wish to have the proof sheets addressed to me at Downton Castle Ludlow ⁴. Mr Hamilton will give me a frank for this purpose at the foreign office⁵. If there is no hurry I shall be in town the first week in Octr. Pray have the kindness to again check this matter & to tell my servants in Gro[sve]n[or] Street that I shall be in town before the end of the first week in Octr. & desire them to have the carpet put down in my bed room & sitting room & the bed well aired.

Will you be so good as to get for me some pure tin & some tubes of glass bent in this form with wires some of platinum & some of iron cemented ie hermetically sealed into the top. I have some experiments to make of a perfectly new kind ⁶. Pray desire Mr Newman to get these tubes ready. Six will be sufficient six inches high & the lower leg by which they are to be fitted about 3 1/2. The wire 2 inches within - & about 1/30 or 1/40 of an inch in diameter.

I hope to find some new substance in the Laboratory on my return.

I am | My dear Mr Faraday | Very sincerely your friend & well wisher | H. Davy
