It gives me very great pleasure at all times to have the honor of a letter or even a verbal message from you but that pleasure was on the occasion of your last letter mixed with pain that I should inadvertently have grieved you. I am extremely indebted to you for your kindness in putting me right and as I had a paper in the press I instantly stopped the printer's progress and applied to the President His Royal Highness the Duke of Sussex and obtained leave to attach a note to the paper amending my error 1. I have also urged the printer forward that I might procure a copy of the note which I now send to you and I hope you will find it every thing that you wished for. I am exceedingly sorry for my mistake but when you have read the note I am sure you will not be surprised at it.
Occupation presses on me to such a degree that I have barely time now to write these few words and I think I may therefore assume that the note will answer the greater part of your letter. I am delighted to find that you are experimenting on the subject and shall be quite anxious to read your paper on the action of heat. From what you state I should suppose the effects are altogether new but shall scrupulously refrain from making the experiments or even thinking on the matter until I see your results. I am still at work and shall send you papers as they come out. I have just sent in one - (my fourth series of experimental researches) on a new law of Electric conduction 2 to the Royal Society but it has not yet been read. I have another in hand but the experiments are incomplete 3.
Wishing you full recovery of health & spirits that you may still vigorously & successfully pursue what I know gives you such delight and is to you a source of so much honor I am My Very dear Sir Yours Most faithfully M. Faraday
