[15] C. 14. Nicolai, in the first part of his Travels, has translated
this description of an odometer, and illustrated it with a figure by H.
Catel.
[16] This palace, with its ornaments, is described in the Memorie
concernenti la citta di Urbino. Roma, 1724. fol. The figure to which I
allude is in plate 53. Bernardino Baldi, the author of the descriptive
part, considers it as an odometer.
[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.

[24] This machine was used by Sulzer during his tour. See his Journal,
published at Leipsic, 1780, 8vo, p. 3. 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.
