‎---- EDITION ORIGINALE ---- TRES RARE ---- BEL EXEMPLAIRE ---- "Boullenger (Nicholas Antoine), (1722/1759), a well-known french writer, whose extensive studies were interrupted by his death, in 1759, at the early age of thirty seven, gives, in this "Traité de la Cause et des phénomènes de l'électricité, accounts of many important observations made in the electrical field. His attention were carefully given to ascertaining the degrees in which different substances are capable of being excited, and he gives several lists of such, inferring therefrom that the most transparent and the most brittle are always the most electric. At pp. 64 and 124, he stated that electricity affects mineral waters much more sensibly than common water ; that black ribbons are more readily attracted than those of other colours, next to the black being the brown and deep red ; and that, of two glass cylinders exactly alike, except that one is transparent and the other slightly coloured, the transparent one will be the more readily exicted". (Motteley pp. 191/192) ---- "In part I, it is said that bodies which aremost susceptible of electrification are transparent and brittle, p. 63 ; constructon of the first cylindrical electrical machine attributed to Andrew Gordon, a Scotch benedictine living at Erfurt, p. 23 ; dark-colored ribbons most strongly attracted, p. 124 ; propagation of electricity, p. 4 ; principle of the siphon recorder, p. 59, experiments with flames, p. 67".
