James South to Faraday   22 June 1825

My dear Sir,

You will much oblige me by shewing to Monsr la Vicomte de Dreury Brézé¹, fils du Grand Maitre du Cérémonies de la Cour de France, the Royal Institution Laboratory Museum &c – if also Mr. Brande should be out of Town you will perhaps have the kindness to accompany him to the Laboratory of the Apothecaries Company – he is desirous of seeing the principal manufactories of England, any assistance you can give him towards facilitating the object of his visit to our Country, will be deemed a favor conferred on

My dear Sir | Yours very truly | J. South

Passy Rue Franklin No 19 | June 22, 1825

PS By a letter I received from Sir Humphry Davy on Monday last² I was glad to find that Chemistry has to thank you for fresh discoveries³ – pray inform us on this side of the water what are the components of Nitrogen⁴ – when I got a glimpse first of your name & afterwards of the word discovered I had hoped to have found the information we want.

Address: To | Michael Faraday Esq | Royal Institution | No 21 Albemarle Street | near Bond Street
