[Royal Institution embossed letterhead] | 12 March 1861.
Sir
I hear that the Prince Consort is to be at Burlington House (Royal Society) on Saturday evening2. A great discovery in physical optics has lately been made by Bunsen & Kirch[h]off of Heidelberg which will be illustrated at Burlington House by Professor Roscoe on that Evening. If his Royal Highness has not yet seen the chief experiment I think I am right in believing he would wish to see it and therefore take the liberty of mentioning the above circumstances to you3.
I have the honor to be | Sir | Your very Obedient humble Servant | M. Faraday
Major General | The Honorable Chas. Grey | &c &c &c
