Faraday's reply to Abbott, 1815 [1]

Both comments are at the tail of the letter in French and their translation is in the footnotes.
I think Faraday was pulling Abbott's leg here so that he wouldn't be inclined to travel south to find out for himself. Like a fisherman would in protecting his favorite fishing holes.
