Humphry Davy to Faraday   1 October 1815

Octr 1st 1815.

I shall feel obliged to you if you will post pay this letter and send it by the foreign post.

I shall be in town in about ten days

Will you be so good as to desire Mr Newman to get down for me some strong glass cylinders like the glasses for Argands lamps but 10 inches long & much thicker so as to stand an explosion; they must be open at both ends; but one end may be smaller than the other thus ; the diameter about 2 inches. 4 will be enough[.]

Always your sincere | Well wisher | H. Davy

Endorsed: Wetherby first Oct 1815 Lascelles¹
