letters; and by means of machines placed at intervals such that each was distinctly<br />
visible from the next, messages could be conveyed through 150 miles within a<br />
quarter of an hour. Chappe's contraption was adopted by the Legislative Assembly<br />
in 1792, and in the following year Chappe was appointed ingénieur-télégraphe. The<br />
optical telegraph was first used for an official transmission in 1794, and remained<br />
widely in use in France until 1855, when it was superseded by the electric telegraph.<br />
This work was translated from a German publication issued the same year with the<br />
title Beschreibung und Abbildung des Telegraphen oder der neuerfundenen<br />
Fernschreibemaschine in Paris, but clearly published in Italy. A brief introduction to<br />
the principles of the device is followed by an eyewitness account of the first<br />
conveyance of a message from a device mounted on top of the Louvre. This is<br />
depicted on the first of the finely engraved plates. The other plates show the agreed<br />
signals and the transcription of a message in German.<br />
There was another Italian edition, printed in Rome (Roma, si vende presso Agapito<br />
Franzetti) the same year; not traced in NUC, RLIN or the Italian on-line catalogue;<br />

1790s. £ 350<br />
Folio, pp. 19, large armorial vignette to title; very clean and crisp in<br />
original yellow wrappers; a little dog-eared, else fine.<br />
First and only edition of an anonymous publication analysing the chemical processes<br />
involved in the production of mineral acids, especially for cleaning and disinfecting<br />
purposes, and as a form of air-purifier to reduce the risk of infection. A number of<br />
recipes are given, both for household use and, more importantly, for use in hospitals.<br />
The anonymous author stresses in particular its application in hospitals or on ships,<br />
to sanitise after the outbreak of infectious diseases, such as yellow fever, and the<br />
plague.<br />
