"He devised many of his experiments, in the process consulting records of other experimenters, among them those of the Accademia del Cimento. Musschenbroek translated their accounts into Latin, adding reports concerning his own work (1731)." – Encyclopedia.com
The work opens with Musschenbroek's Oratio de Methodo Instituendi Experimenta Physica, regarding his views on experimental philosophy, as inspired by Newton. "Underlying Musschenbroek's lectures demonstrated with experiments was the experimental philosophy the principal source of inspiration was Newton, but Galileo, Torricelli, Huygens, Réaumur, and others were important to this school." – DSB, IX, p. 596. The Accademia del Cimento [Academy of Experiments] was founded in Florence in 1657. Among the founding members were Borelli, Steno, Redi, Cassini, Viviani and Torricelli, these final two being disciples of Galileo. This makes the Accademia older than either the Royal Society or the Académie des Sciences. Count Lorenzo Magalotti's text includes accounts of experiments on temperature and air pressure (including Torricelli's invention of the barometer), the velocity of sound and light, phosphorescence, magnetism, amber and other electrical bodies, the freezing of water, etc. The many fine plates in this translation illustrate the Accademia's work as well as Musschenbroek's own subsequent experiments. – Wolf, History of science, I, pp. 55-59.2 parts in 1.
Musschenbroek (1692-1761), professor of natural philosophy and mathematics at Utrecht and, later, professor of experimental physics at Leyden. He was one of the most celebrated physicists and investigators of his time; the experiments he describes are classics in primary instruction.
"Musschenbroek's earliest account of electricity (1731), the estimable notes to his Latin translation of the Saggi, is fuller, more circumspect and less coherent than 's Gravesande's, which he later entertained favorably. Two curious points emerge from the notes. To resolve the discrepancy between the results of Boyle and Hauksbee, who respectively did and did not succeed in generating electricity in vacuo, Musschenbroek hit on an unprecedented and prescient idea; remarking that Boyle used amber and Hauksbee glass, he concluded that these substances have different electricities… The second point concerns repulsion. Musschenbroek records without emphasizing Hauksbee's observation that light bodies are sometimes repelled farther than they are attracted; he squeezes it into a note that also gives an excellent prescription for rubbing the tube – always end with your hands together – and a warning about atmospheric humidity. He does not recognize that the Saggi require updating about repulsion, and concentrates on the perplexing behavior of screens, the opacity of muslin and the transparency of glass." – J. L. Heilbron, Electricity in the 17th and 18th Centuries: A Study of Early Modern Physics, (1979), p.242.
