[17] In Joannis Fernelii Ambianatis Cosmotheoria, Parisiis 1528, we find only the following passage respecting this invention:--“Nec vulgi supputatione satiatus, vehiculum, quod Parisios recta via petebat, conscendi, in eoque residens tota via 17024 fere rotæ circumvolutiones collegi, vallibus et montibus ad equalitatem, quoad facultas nostra ferebat, redactis. Erat autem rotæ diameter.” In Almagesti novi parte posteriori, tomi primi, Bononiæ 1651. fol. the author, Riccioli, says that Fernel contrived his carriage in such a manner, that the revolutions of the wheels were shown by a hammer striking on a bell. Where that jesuit discovered this I cannot learn. [18] Doppelmayer, Nachricht von Nurnberg Künstlern, p. 82. Will, Nurnbergisches Gelehrten-Lexicon, iii. p. 156.

It has been since improved by Schumacher, a clergyman at Elbing, by Klindworth, Catel at Berlin, and by an anonymous clergyman in the Schwabisches Magazin, 1777, p. 306. [25] This model is preserved in the collection of the Academy. [26] There is a figure of it in the Penny Cyclopædia, vol. xvii. p. 367. MACHINE FOR NOTING DOWN MUSIC. As I have occasionally mentioned in the preceding article, a machine for noting down any piece of music played on a harpsichord or other musical instrument, I shall here add a short history of the invention of it, as far as I know; and with the greater pleasure, as another nation has laid claim to it, though it belongs to my countrymen. It appears incontestable, that a proposal for inventing such a machine was first made known by an Englishman. In the month of March 1747, John Freke transmitted to the Royal Society a paper written by a clergyman of the name of Creed, which was printed in the Philosophical Transactions under the following title:--A Demonstration of the possibility of making a machine that shall write extempore voluntaries, or other pieces of music, as fast as any master shall be able to play them upon an organ, harpsichord, &c.; and that in a character more natural and more intelligible, and more expressive of all the varieties those instruments are capable of exhibiting, than the character now in use[27]. The author of this paper however points out the possibility only of making such a machine, without giving directions how to construct it.
