London, 1914. No wrappers, but stiched. All three papers contained in: ""Philosophical Magazine"", Sixth Series, Vol. 27. No. 159. March 1914. The whole issue issue offered (=no. 159): pp. 397-540 and 2 plates.Rutherford's paper.pp. 488-498. - Darwin's paper: pp. 499-506. - Bohr's paper: pp. 506-523. All clean and fine.
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). Bohrs paper on The Stark effect appeared in 1914, the paper offered here. - Rosenfeld. Niels Bohr' publications No. 10).

Schmidt's paper: pp. 141-151, textillustr. A tear to inner lower corners of pp. 24-32. (not affecting Schmidt's paper). Clean and fine.
First printing of Schmidt's full exposition, in which he describes his discovery of the radioactivity of Thorium. Schmidt and Marie Curie independently demonstrated the radioactive quality, but Schmidt's demonstration took place a few months before Curie's. The discovery was announced, but not described in full, in a short message published in ""Verhandl. d. Phys. Gesellsch. zu Berlin, 1898.""Schmidt made his discovery while examining ""many elements and compounds"" in an effeort to determine whether any of the rays that were emitted bore a resemblance to those that Henri becquerel had found emerging from uranium and uranium compounds. He located only one such element, thorium, and immediately conducted absorption, ionization, reflection, refradction, and poklarization studies to determine the characteristics of its rays. Having combined a misinterpretation of Becquerel's with one of his own, Schmidt concluded that thorium rays most resembled Röntgen rays - a conclusion that soon required revisoln in view of the researches of Marie Curie and Ernest Rutherford.""(DSB XII, p. 191.

First appearance of an importent paper in the history of biology, in which Schwann describes his discovery and isolation of pepsin, the substance in the stomach that aids digestion of eggwhite. It is the FIRST KNOWN ANIMAL ENZYME. The paper appeared at the same time in ""Archiv für Anatomie, Physiologie und Wissenschaftliches Medicin""Theodor Schwann (1810-1882) was a great German physiologist, pathologist, and experimenter. One of the founders of the cell doctrine and of the idea of the living nature of yeast. Born at Neuss, near Düsseldorff. A catholic, educated in the Jesuit Gymnasium in Cologne. Intended for the church but took to medicine. He was a pupil of Johannes Müller and a collegueand lifelong friend of J. Henle, the anatomist. In Berlin Schwann was Johannes Müller's assistent for five years, and it was then that he discovered pepsin in 1836 (the paper offered).Parkinson ""Breakthroughs"" 1836 B.The issue contains other importent papers by Seebeck, Matteucci, Marchand, G.

"SEFSTRÖM, N.-G. (NILS GABRIEL). - THE DISCOVERY OF VANADIUM.

(1831)
(Paris, Crochard, 1831). No wrappers. In: ""Annales de Chimie et de Physique, Par MM. Gay-Lussac et Arago."", tome 46, Cahier 1. Pp. 5-112. (Entire issue offered). Sefström's paper: pp. 105-111.
First printing of the paper in which Sefström announced his discovery of a new element in iron from the Taberg mine in Småland. He named it Vanadium from the goddess Vanadis.Parkinson ""Breakthroughs"" 1831 C.The discovery and isolation of Vanadium has a long story to tell. In reality it was found by del Rio in 1801, he named it Erythronium, but upon further study he decided that he was mistaken as his further studies showed that it was made up of a basic lead chromate.
