A FINE AND UNIQUE MANUSCRIPT, CRAFTED IN THE FASHION OF THE ARTS AND CRAFTS MOVEMENT AND SPECIALLY BOUND BY ONE OF THE GREATEST AMERICAN FEMALE BOOKBINDERS OF THE 20TH CENTURY FOR HER FRIENDS: THE CHRISTIAN SOCIALIST ACTIVIST GEORGE HERRON, A MINISTER, AND HIS YOUNG SPOUSE CARRIE RAND, THE HEIRESS OF A BANKING FAMILY, WHO EMBRACED THE SOCIALIST CAUSE. 8vo (233 x 154 mm); bound in full burgundy morocco decorated with gilt flames embossed to boards in a double gilt frame; signed «H. G. H.», short for Helen Gowen Haskell; within the double gilt frame are the gilt letters «H» and «R», the initial of the spouses surnames, Herron and Rand, both embossed in gilt circles; five raised bands to spine; gilt flames and gilt letters «H» and «R» in gilt circles embossed to spine; double gilt frame with gilt flames to the head and the foot of both front and rear pastedown; all edges gilt; endpapers blank; leaves measuring 228 x 148 mm, pages: [156]; manuscript in black ink with initials for each section in red ink; page-frames in red ink; two drawings in the text. Original autograph document. Signed by most contributors (also referred to as "Social Democratic comrades") in red-ink boxes in the text. Original manuscript by the well-known Liverpudlian socialist Leonard Abbott, a follower of William Morris; published in pamphlet form in the prestigious «International Socialist Review» in July 1901 (pp. 14-20), it was met with public outcry and caused a scandal, as illustrated by Rose L. Martin in her detailed account of the circumstances in which the wedding came about in «Fabian Freeway. High Road to Socialism in the U.S.A. 1884-1966». At the turn of the 19th century, an event shook American society like a powerful earthquake. In the aftermath of the scandalous event, outburst of rage and indignation stirred the country, especially in the most conservative and traditionalist circles. The clergyman, educator, author, and Social Gospel advocate George D. Herron, a married father-of-four, left his lawfully wedded wife Mary out of love for another woman, Carrie A. Rand. The following unconventional union between Herron and Rand took place on May 25, 1901, in a New York apartment under the appellation of socialist wedding. Carrie Rand was the daughter of a lumber baron and banker and Caroline Rand, who donated profusely to Socialists and those who believed in their cause, whose inheritance would later fund and found the Rand School of Social Science in 1906. George D. Herron (1862-1925) was at one time a Christian Socialist minister, a founder of the Rand School of Social Science, a member of the Socialist Party, and the author of books and pamphlets on social and religious issues. Pastor William Franklin Lemmons greatly disapproved of the wedding, as he later wrote in his book «The Evils of Socialism». The binder Helen "Nellie" Gowen Haskell Noyes (1864-1940) was an esteemed American binder, whose lifelong work earned her the Guild of Bookworkers «Lifetime Achievement Award» in 1937. A manuscript book, bound by a great American woman binder, which deals with socialism, universal social and civil rights, as well as the feminist cause. This book symbolises the American fight against the establishment, traditional social and legal norms, and the rule of capitalism. It was the wedding gift that the inner circle of socialist, progressive and anarchist friends ("comrades") of George D. Herron and Carrie Rand Herron crafted on the occasion of their scandalous so-called "socialist wedding," which had to set the standard for the bright future of international socialism that they hoped was nigh. The couple fled the US and took refuge in Italy after their performance of a socialist wedding provoked a storm of criticism and violent personal attacks directed at them.

First printing of a main paper by the "Father of Geophysics" in which he shows that the effect of the tides was to force a retreat of the moon from the earth - thus going backward in time in the history of the earth, he concludes that the earth had been in contact with the moon, and this represents the time at which the whirling earth threw off a portion of its outer crust by centrifugal action, loosing angular motion in that way."Darwin's most significant contribution to the history of science lies in his pioneering work in the application of detailled dynamical analysis to cosmological and geological problems. That many of his conclusions are now out of date should in no way diminish the historical interest in his experiments, nor the importent service thet he rendered cosmogony by the example he gave of putting various hypotheses to the test of actual calculations.

Aggiungi al carrelloLondon, 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).
