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

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

 inventor, CnN.+:us of Loyden, in ignorance of the actual inventor, E. G. v. Kleist of Cammin. To show its powerful 

 action, he electrified before tlie King ISO Carthusian monks who formed a line !»()0 feet long. 



He propounde<l 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 j^rojected on an arc of 180°, were to show the amount <>f the 

 electric charge by the rate of their angular divf-rgence.

' Les editions de 1759, et celles <iui sont posterieures, sont les plus estimees.' — Querard. ' On y admire une methode 

 inconnue jusqu'alors, une nettete singuliere dans les idees, et dans la maniere de les exprimer. XoUet eut I'art 

 d'assujettir tout li I'exp^rience, de soumettre les verites intellectuelles au jugement des Hens.'—Grandji'an 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 imjjroved percussion apparatus, the above work is still of value for containing i)erhap8 the most 

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