George Herbert to Faraday   22 November 1852

My dear Mr. Faraday

I can hardly summon up sufficient courage to intrude upon your already overoccupied time but your great kindness upon all occasions to me makes me hope you will look leniently upon the Intruder. I have made the enclosed estimate (based as you will see upon your observations) of the comparative amount of light thrown upon the horizon from the different apparatus in use by this Board¹[.] The conclusion arrived at in regard to the 1st order revolving (French) light being so nearly that arrived at by Mr. Drummond² leads me [to] think that the estimate may not be altogether incorrect, and if you will do me the favor of returning me the enclosed with just a word to say whether I have understood the matter aright or not, you will greatly oblige my dear Mr. Faraday

Your very faithful | George Herbert
