‎(London, Harrison and Sons, 1879). 4to. No wrappers as extracted from ""Philosophical Transactions"" 1879 - Vol. 169 - Part II. Pp. 777-822 a. 5 plates.‎

‎First printing of Robinson's new experiments and researches into the constants of the Cup-Anemometer which he invented in 1846 by modifying Whewell's instrument by the introduction of the now-familiar windmill with hemispherical cups.""A simple type of anemometer is the cup anemometer, invented (1846) by Dr. John Thomas Romney Robinson, of Armagh Observatory. It consisted of four hemispherical cups each mounted on one end of four horizontal arms, which in turn were mounted at equal angles to each other on a vertical shaft. The air flow past the cups in any horizontal direction turned the cups in a manner that was proportional to the wind speed. Therefore, counting the turns of the cups over a set time period produced the average wind speed for a wide range of speeds. On an anemometer with four cups it is easy to see that since the cups are arranged symmetrically on the end of the arms, the wind always has the hollow of one cup presented to it and is blowing on the back of the cup on the opposite end of the cross.""‎

(Manchester Memoirs.). Volume LIII. (1908-09). Entire volume offered. The volume contains 24 papers, all with seperate pagination. Rutherford's paper: pp. 1-3.‎

‎First printing of the paper which Rutherford and Royds gave the final proof that the alpha particle are atoms of helium. The present paper was read on November 3rd 1908 and published on the 19th. It was reprinted in Philosophical Magazine and that paper is dated November 13, 1908 and published February 1909.""After nearly a decade of labor, Rutherford was finally prepared to state... what the alpha particle really was ""We may conclude that an alpha-particle is a helium atom, or, to be more precise, the alpha-particle, after it has lost its positive charge, is a helium atom"". In a paper together with Royds, completed in November 1908, he was even more emphatic: ""We can conclude with certainty... that the alpha-particle is a helium atom... They had shown that a discharge sent through a volume in which alpha-particles from radium had been collected produced the characteristic helium spectrum !""(Pais ""Inward Bound"", p. 61).""Rutherford’s early conviction that the alpha particle was a doubly charged helium atom, but he had not succeeded in proving that belief. In 1908 he and Geiger were able to fire alpha particles into an evacuated tube containing a central, charged wire and to record single events. Ionization by collision, a process studied by Rutherford’s former colleague at Cambridge, J. S. E. Townsend, caused a magnification of the single particle’s charge sufficient to give the electrometer a measurable ""kick."" By this means they were able to count, for the first time accurately and directly, the number of alpha particles emitted per second from a gram of radium.This experiment enabled Rutherford and Geiger to confirm that every alpha particle causes a faint but discrete flash when it strikes a luminescent zinc sulfide screen, and thus led directly to the widespread method of scintillation counting. It was also the origin of the electrical and electronic methods of particle counting in which Geiger later pioneered. But at this time the scintillation technique, now proved reliable, was more convenient. This counting work also led Rutherford and Geiger to the most accurate value of the fundamental electric charge e before Millikan performed his oil-drop experiment. They measured the total charge from a radium source and divided it by the number of alphas counted to obtain the charge per particle. Since this figure was about twice the previous values of e. they concluded that the alpha was indeed helium with a double charge. But Rutherford still desired decisive, direct proof"" and here his skilled glassblower came to his aid. Otto Baumbach in 1908 was able to construct glass tubes thin enough to be transparent to the rapidly moving alpha particles yet capable of containing a gas. Such a tube was filled with emanation and was placed within a larger tube made of thicker glass. In time, alpha particles from the decaying emanation penetrated into and were trapped in the space between inner and outer tubes: and when ROYDS SPARKED THE MATERIAL IN THIS SPACE, THEY SAW THE SPECTRUM OF HELIUM.""

‎First appearance of this seminal paper which contains Rutherford's discovery of artificial transmutation. He here discovered, that the atomic nucleus (discovered by him in 1911) itself had a structure, when, by bombarding nitrogen with alpha particles, he produced THE FIRST ARTIFICIAL TRANSFORMATION OF AN ELEMENT INTO ANOTHER, and what was left after the bombardment had to be those of oxygen atoms. - Thus thus began the age of nuclear physics.""Rutherford was .. the first man ever to change one element into another as a result of the manipulations of his own hands. He had achieved the dream of the alchemists. He had also demonstrated the first man-made ""nuclear reaction"". By 1924 Rutherford had managed to knock protons out of the nuclei of most of the lighter elements."" (Asimov).""A few years before, Marsden had noticed scintillations on a screen placed far beyond the range of alpha particles when these particles were allowed to bombard hydrogen. Rutherford repeated the experiment and showed that the scintillations were caused by hydrogen nuclei or protons. This was easily understood, but when he substituted nitrogen for the hydrogen, he saw the same proton flashes. The explanation he gave in 1919 stands beside the transformation theory of radioactivity and the nuclear atom as one of Rutherford’s most important discoveries. This, he said, was a case of artificial disintegration of an element. Unstable, or radioactive, atoms disintegrated spontaneously"" but here a stable nucleus was disrupted by the alpha particle, and a proton was one of the pieces broken off."" (DSB).PMM: 411.‎

‎First edition and first printing of all three papers. Rutherford, in this paper for the first time identifies the hydrogen nucleus, and called it the 'positive electron'. He later called it 'the proton' . In his definitive paper of 1911 he estimated the radius of the nucleus, a hundred thousand times smaller than that of an atom. Darwin in his paper (offered here) gave a more precise measure.In the first lines of the paper Rutherford outlines the content ""The present paper and and the accompanying paper by Mr. C. Darwin (the second paper offered here) deal with certain points in connection with the ""nucleus"" theory of the atom which were purposely omitted in my first communication on that subject (Phil. Mag. May 1911). A brief account is given of the later investigations which have been made to test the theory and of the deductions which can be drawn from them. At the same time a brief statement is given of recent observations on the passage of alpha particles through hydrogen, which throw importent light on the dimensions of the nucleus."" - Rutherford had studies alpha-particles intensely in the years before 1914 and proved quite conclusively that the individual particle was a helium atom with its electrons removed. The alpha particles were like the positive rays that had been discovered by Goldstein (1886), and now in 1914 (the paper offered) Rutherford suggested that the simplest positive rays must be those obtained from the hydrogen and that these must be the fundamentall positively-charged particle. He names it a 'positive electron'.Darwin, in the paper offered ""concluded from the known data:""No force proportional to some power of the distance other than the inverse square can give the dependence (the Rutherford scattering cross section) on (the initial velocity)"", and he then calculated the distance of closest alpha-particle-nucleus approach.The paper by Niels Bohr relates to ""The Stark effect"". In 1913 appeared ""an importent new discovery: when atomic hydrogen is exposed to a static electrical field its spectral lines split, the amount of splitting being proportional to thefield strenght (the linear Stark effect). After Rutherford read this news in ""Nature"", he at once wrote to Bohr:'I think it is rather up to you at the present time to write something on....electric effects.'"" (A. Pais).

Savart showed that the bridge transmits the string’s vibrations that the plate can be made to vibrate at any frequency" and that the corresponding mode is a modification of an unforced mode. He demonstrated that the sound post also serves to transmit vibrations, and he explained that it therefore should not be placed under a nodal line. Thinking that symmetry and regularity would produce the best tone, Savart built a trapezoidal violin with rectangular sound holes.

‎First French announcement of this epochal event in the history of medicine, the discovery of the etiology and prevention of childbed fever. First announce by Ferdinand von Hebra in December 1847, then followed (only 2 months) after by the French announcement.""Although Semmelweis's importent discoveries were made in the 1840s, he did not publish them immediately. The first printed reports of his findings were written by his collegues and were published in various German, French, or English Journals. Semmelweis himself gave three lectures before the Imperial and Royal Medical Society of Vienna in 1850 but did not publish his complete discussion of ""The etiology, concept, and prophylaxis of childbeed fever"" until 1861, having previously contributed several shorter accounts to Hungarian medical journals.""(Norman ""One Hundred Books famous in Medicine"", p. 265).Semmelweis demonstrated that puerperal fever (also known as childbed fever) was contagious and that this incidence could drastically be reduced by appropriate hand washing by medical care-givers. He made this discovery in 1847 while working in the Maternity Department of the Vienna Lying-in Hospital. His failure to convince his fellow doctors led to a tragic conclusion. However, he was ultimately vindicated. While employed as assistant to the professor of the maternity clinic at the Vienna General Hospital in Austria in 1847, Semmelweis introduced hand washing with chlorinated lime solutions for interns who had performed autopsies. This immediately reduced the incidence of fatal puerperal fever from about 10 percent (range 5-30 percent) to about 1-2 percent.Toward the end of 1847, accounts of Semmelweis's work began to spread around Europe. Semmelweis and his students wrote letters to the directors of several prominent maternity clinics describing their recent observations. Ferdinand von Hebra, the editor of a leading Austrian medical journal, announced Semmelweis's discovery in the December 1847 and April 1848 issues of the medical journal. Hebra claimed that Semmelweis's work had a practical significance comparable to that of Edward Jenner's introduction of cowpox inoculations to prevent smallpox.Garrison & Morton: 6275 (German version).‎
