(title slightly mended and name inked out, otherwise a fine copy), 8s Qd 1765 



One of the author's most valuable works, including a description of his electrical machine. The author made 

 numerous interesting experiments with the Leyden jar, which name he introduced in honour of the supposed 

 inventor, CITNJEUS of Leyden, in ignorance of the actual inventor, E. G. v. KLEIST of Cammin. To show its powerful 

 action, he electrified before the King 180 Carthusian monks who formed a line 900 feet long. 



He propounded a twofold-motion fluid hypothesis of electricity, by which he attempted to explain electric attraction 

 and repulsion ; investigated the influence of electricity on the germination of seeds ; and constructed a primitive 

 electroscope consisting of two linen threads, which, being projected on an arc of 180, were to show the amount of the 

 electric charge by the rate of their angular divergence.

' Les editions de 1759, et celles qui sont posterieures, sont les plus estimees.' Queranl. ' On y admire une methode 

 iuconnue jusqu'alors, une nettete singuliere dans les idees, et dans la maniere de les exprimer. Nollet eut 1'art 

 d'assujettir tout a 1'experience, de soumettre les verites intellectuelles au jugement des sens.' Grandjean de, Fouchy. 



The author was the discoverer of endosmosis, and in France is considered the father of experimental physics. Besides 

 giving his invention of an improved percussion apparatus, the above work is still of value for containing perhaps the most 

 complete illustrative account of physical apparatus in use during the middle of the Eighteenth Century.
