Mentions that Mesmer is in Paris. No mention of the armonica \textit{per se}, but Mesmer looms large in the history of the armonica.

I hear from Fontana the Vienna conjuror Dr. Mesmer is at Paris, that he has been presented to the Royal academy, that he still pretends a magnetical effluvium streams from his finger and enters the body of any person without being obstructed by walls or any other obstacles, and that such stuff, too insipid for to get belief by any old woman, is believed by your friend Mr. Le Roy, who protects him and will recommend him in London, where he has a mind to exercise his magnetical effluvia.
