‎First edition of Millikan's landmark experiment in which he first provided the definitive proof that all electrical charges are exact multiples of a definite, fundamental value, namely the charge of the electron which in essence made possible the measurement of the electrical charge. In this paper, Millikan makes ""the important discovery that individual drops always carried an exact multiple of the smallest charge measured - this being the first accurate measurement of the charge of the electron"" ( Davis, Science in the Making, Volume 3, 10-11). Today it is primarily known as the 'oil-drop experiment'. ""By 1909 Millikan was deeply involved in an attempt to measure the electronic charge. No one had yet obtained a reliable value for this fundamental constant, and some antiatomistic Continental physicists were insisting that it was not the constant of a unique particle but a statistical average of diverse electrical energies. Millikan launched his investigation with a technique developed by the British-born physicist H. A. Wilson" it consisted essentially of measuring, first, the rate at which a charged cloud of water vapor fell under the influence of gravity and then the modified rate under the counterforce of an electric field. Using Stokes's law of fall to determine the mass of the cloud, one could in principle compute the ionic charge. Millikan quickly recognized the numerous uncertainties in this technique, including the fact that evaporation at the surface of the cloud confused the measure of its rate of fall. Hoping to correct for this effect, he decided to study the evaporation history of the cloud while a strong electric Held held it in a stationary position.But when Millikan switched on the powerful field, the cloud disappeared" in its place were a few charged water drops moving slowly in response to the imposed electrical force. He quickly realized that it would be a good deal more accurate to determine the electronic charge by working with a single drop than with the swarm of particles in a cloud. Finding that he could make measurements on water drops for up to forty-five seconds before they evaporated. Millikan arrived at a value for e in 1909 which he considered accurate to within 2 percent. More important, he observed that the charge on any given water drop was always an integral multiple of an irreducible value. This result provided the most persuasive evidence yet that electrons were fundamental particles of identical charge and mass.Late in 1909 Millikan greatly improved the drop method by substituting oil for water. Because of the relatively low volatility of this liquid, he could measure the rise and fall of the drops for up to four and a half hours. Spraying the chamber with radium radiation, he could change the charge on a single drop at will. His overall results decisively confirmed the integral-multiple values of the total charge. As for the determination of e itself, Millikan found that Stokes's law was inadequate for his experimental circumstances because the size of the drops was comparable with the mean free path of the air. Using the so-called Stokes-Cunningham version of the law, which took this condition into account, by late 1910 he had computed a charge for e of 4.891×10-10 e.s.u. Realizing that the accuracy of this figure was no better than that of the key constants involved in the computation, Millikan painstakingly reevaluated the coefficient of viscosity of air and the mean-free-path term in the Stokes-Cunningham law. In 1913 he published the value for the electronic charge, 4.774±.009×10-10 e.s.u., which would serve the world of science for a generation."" (DSB). In 1923 Millikan became the first American-born Nobel laureate for his work on determination of Planck's constant on the basis of Einstein's theory of the photoelectric effect.‎

‎Paris, Imprimerie de Ch. Jouaust, (1860). 7 pieces in 1 volume. 2 pp.; 16 pp.; 24 pp.; 13, (1) pp.; 14 pp.; (4), 71, (1) pp.; 40 pp. 4to. Modern half morocco, marbled boards, spine lettered in gilt. Not in Siegelaub, Bibliographica Textilia historiae; Hoefer, vol. xx, cols. 668-678; Dictionnaire de Biographie Française, vol. 16, cols 168-170. Philippe de Girard invented the machine for spinning linen along principles still valid today. He was awarded a million francs by Napoléon and, in anticipation started three factories. But due to political circumstances and the fact that Napoléon did not keep his promise, his factories, very succesful from the start, faced soon ruin and de Girard was imprisoned. Ruined and betrayed by two collaborators, he accepted an invitation by the Austrian government. He again set up a factory and was again succesful. When de Girard was awarded the gold medal given by the Société d'encouragement pour l'Industrie nationale, he returned to France. Despite his brilliant discoveries (de Girard was the inventor of many more novelties) and the intervention on his behalf by journalists, politicians and intellectuals, the government refused to give him any financial help or reward. De Girard died in 1845 and his niece continued to find a way to get the money once awarded to de Girard. Also Charles Dupin appealed to the government, but all to no avail. - A few pieces have contemporary underlining and handwritten notes and comments in the margins, three texts have been bound with their original, printed covers, the last text has a handwritten dedication to Monsieur Gudin or Godin by the Comtesse Vernède de Corneillan, née de Girard. ‎
