Faraday to William Crookes   14 January 18631

Royal Institution | 14 Jany 1863

My dear Sir

I shall be very glad to see the Thallium2 subjected to the Magnetic force[.] It would be better to do so this week - Will next Friday3 at 12 o’clk suit you - or 11 o’clk - or if not Friday Saturday at 11’ or 12 o’clk. Let me know your choice as soon as you can. If you have more than one specimen of Thallium fit for the purpose - bring them that we may see if there be differences[.]

Very Truly Yours | M. Faraday

Wm. Crookes Esqr | &c &c &c
