Nouvelles réflexions de M. Rameau sur sa demonstration du principe de l’harmonie, servant de base à tout l’art musical théorique et pratique.
First edition; rare. ‘This short treatise, which appeared in 1752, is ostensibly a postscript to Rameau’s Démonstration [du principe de l’harmonie], published two years earlier. It nevertheless marks a radical shift in Rameau’s thinking about the corps sonore [Rameau’s term for any vibrating system which emitted harmonic partials above its fundamental frequency]. In that same year, the architect Charles Briseux (c. 1680–1754) published a Traité du beau essential dans les arts in which he used the evidence of Rameau’s discoveries to demonstrate that architecture was based on the principles of harmony. Rameau seized on this corroboration of his theories, which confirmed his growing belief that the principles derived from the corps sonore were “common to all those arts of taste that have our senses for object and proportions for rules”. By now, too, he had discovered the “sensationalist” psychology of John Locke . . . which held that all knowledge is acquired primarily through the senses. Rameau could thus validate the corps sonore by empirical means, in showing that it was “drawn from nature and perceptible to three of our senses” (hearing, sight, touch). This elevation of experience over reason prompted Rameau to adopt as his watchword the aphorism superbissimum auris judicium (“the judgement of the ear is best”), which appears for the first time in these Nouvelles réflexions. He set great store by this publication, sending copies to the Swiss mathematicians Jean II Bernoulli and Leonhard Euler and the Italian philosopher Francesco Maria Zanotti . . . with a request for their opinions of it’ (Graham Sadler, The Rameau compendium, 2014, pp. 141–2).

EUROPE’S FIRST MAJOR STOCK MARKET BOOM AND COLLAPSE [LAW, John].
Extrait du registre de la Compe. des Indes aujourduy 22 feurier 1720 [and copies of other items relating to Law’s Mississippi System].
A contemporary manuscript by an anonymous copyist reproducing some of the key documents surrounding John Law’s Mississippi system and the Visa instituted following its collapse. In just four years, Law completely transformed the French monetary system to a paper money/bank credit system and substituted shares in the Compagnie des Indes (the Mississippi Company) for the national debt. Having won great personal wealth and risen to the position of France’s finance minister, Law was forced to leave France in December 1720 following the collapse of his system.
