Alexander Stewart Herschel to Faraday   15 June 1864

Collingwood | Hawkhurst | 15th June 1864.

Profr. Dr. Faraday.

Dear Sir

I forgot to assure myself that you were in safe possession of what I consider a very interesting slide, (a photographic copy from a drawing of a Meteor).

The original drawing is the well known drawing of the Great Meteor of 1783 by Mr. Sandby¹; and I would feel greatly obliged to hear from you if this drawing which belongs to Mr. Brayley of the London Institution is anywhere to be found in the lecture room or library of the Royal Institution because it has become unaccountably mislaid, and Mr. Brayley and myself have searched elsewhere for it in vain. If worthy Mr. Anderson has any idea where it has gone I hope you will instruct him to make a search for it before Mr. Brayley calls personally to enquire which he intended to do. It is of a folio-size in Sepia tint, upon stout India paper: and was, to the best of my recollection upon the table after my last lecture on Saturday². I should be very sorry if this is lost[.]

I remain, dear sir | yours faithfully | Alexr. S. Herschel

PS I enclose a small quantity of Magnesium Wire of which I now have a good supply.
