I went to see it yesterday with my old friend the Administrator-in-Chief of the Telegraphs of France, Mr.Poy, who is one of the committee to decide on the best mode for France.

The system on this line is his modification....

I have had a long interview with M.Arago.He is the same affable and polite man as in 1839.

He is a warm friend of mine and contends for priority in my favor, and is also partial to my telegraphic system as the best.

He is President of the Commission and is going to write the History of Electric Telegraphs.
