I shall be glad to see Professor Meister's Account of my Armonica.\ldots I wish your Artist may succeed in making the Armonica. Mr. Professor Gatzert has heard that Instrument plaid upon here by an excellent Hand, and can give you some Account of the great Sweetness of its Tones, and the fine Harmony it produces.
