@. Ampère et l'histoire de l'électricité 

My dear Sir
 
 I take a moment to remind you of an old friend one very much your 
debtor and who wishes to know how you are in health at this waiting period of the year.
 I 
also introduce to you Mr. Smith and certain inventions of his in which I think you will take an 
interest. My friend Mr Lewis speaks highly of Mr Smith's inventions but I have not seen enough 
of them myself to form any opinion upon their final application.
 I am,  
 My dear 
Sir,
 Most Truly Yours,
 
 M. Faraday
