Correspondence between Ampere, Faraday and others

The correspondence refers to previous letters from Ampere and Brewster; mentions Darblay (in London), Hachette and Laplace. Faraday receives French journals irregularly and is impatient for news, especially of Ampere's work.

A transcript of the letter reads:

'Sir,

I yesterday had the honor of receiving your letter of March 29th at the hands of Mr. D'arblay and hasten to answer it fearing that you will have already thought badly of me since it is so long since you wrote it. Mr. 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's 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 and 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 suspence 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 electro-magnetism and it is impossible you can exert yourself on 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 preserve in my public 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 honor to be

Sir

Your Very Humble and Obliged Servant,

M. Faraday.'
