Faraday to André-Marie Ampère   26 May 1822

Royal Institution London | May. 26th. 1822.

Sir

I yesterday had the honor of receiving your letter of March 29th¹ at the hands of Mr. D’Arblay² and hasten to answer it fearing that you will have already thought badly of me since it is so long since you wrote it[.] M D’Arblay apologised by saying he had been out of town[.]

With respect to the letter to Dr. Brewster I have not received it nor can I find that M Hachette mentioned it to me[.] I received some papers of M Laplace’s³ which I sent immediately as addressed but I did not at the same time receive any thing for Dr. Brewster. I hope you will be able to find the letter and make out its history - I was a little alarmed on first reading your letter for having a very bad memory I thought it possible I might have received the letter from M Hachette & forwarded it to Dr. Brewster and since then have forgotten it but I have endeavoured since yesterday to call such a letter to mind but without effect[.] I have not the slightest idea of it - I shall be anxious to know whether you find it or not -

We receive the french journals so irregularly that I am kept in an anxious state of suspense to know what you are doing feeling satisfied you are doing something and that something important[.] From what you have done we are justified in expecting the most fervent devotion in you to electromagnetism and it is impossible you can exert yourself on this this subject without continually adding to the honors you have gained - I owe you very much for your kind expressions[.] Nothing encourages me so much to persevere in my feeble efforts as such commendations as yours.

Begging to be remembered in the warmest manner to Mr. Hachette from whom I hope to hear again when he has leisure I have the honour to be

Sir | Your Very Humble & Obliged Servant | M. Faraday

Address: M. Ampere | &c &c | Paris
