Faraday to George Biddell Airy   23 October 1861

[Royal Institution embossed letterhead] | 23 Octr. 1861

My dear Sir

Very hearty thanks for your letter¹ - Comets? Why not. You know what to ask about them if you cannot yet tell us the answers - & to give their state as a problem only is to do a great deal[.]

Ever Yours | M. Faraday
