‎First appearance of these fundamental paper in cosmology and physics as they contains the FIRST OBSERVATIONAL DATA TO SUPPORT THAT NEWTON'S DYNAMICAL LAWS HOLDS OUTSIDE THE SOLAR SYSTEM. Herschel shows here that the circulating motions of double-stars were under gravitational forces. Until then the validity of the law of gravity was only established within the solar system. Now, a century after the establishment of the law, it was traced out in the motion of incredibly distant stars and the theory first truly earned its title of Universal. The exact proof of the mutual gravitation of the double-stars was only obtained five years after Herschel's death, when the motions of the stars were more precisely dtermined.One of the most notable of Herschel's discoveries of double-stars, binary stars. A first cataloque of such pairs was published early in 1782 and contained 269, of which 227 were new discoveries. ""Twenty years after the publication of his first cataloque Herschel was of Michell's opinion - Michell had expressed the opinion that the odds in favour of a physical relation between the members of Herschel's newly discovered double stars were ""beyond arithmetic"" - but was able to support it by evidence of an entirely novel and much more direct character. A series of observations of Castor, presented in two papers in the ""Philosophical Transaction"" in 1803 and 1804 (the paperS offered ), which were fortunately supplemented by an observation of Bradley's in 1759, had shewn a progressive alteration in the direction of the line joining its two components, of such a character as to leave no doubt that the two stars were revolving round one another"" and there were five oher cases in which a similar motion was observed...it was shown that the double-star was really formed by a connected pair of stars near enough to influence one another's mortion.""(Berry in ""A Short History of Astronomy"" pp. 342-43).‎

‎Reamur's first zoological work, a pioneer-work in which he, as the first, describes the formation of the shells, and in which he proved that they grow not like the other parts of the animal body, by expansion, but by the external addition of new parts : he also assigned the cause of the variety of colour, figure, and magnitude which distinguishes one shell from another.""Réaumur’s first three communications to the Academy, on geometrical subjects, were presented in 1708 and 1709, and demonstrate a degree of mathematical sophistication worthy of a student of Varignon. Had Réaumur decided to remain a mathematician, he might well have been one of the greatest geometers of his age. In November 1709, however, he quite suddenly changed the course of his scientific career by reading a paper on the growth of animal shells. From then on, Réaumur’s work would be characterized by its extraordinary richness and diversity, but never again would he devote himself to the pure mathematical researches that had so fascinated him in his youth.""(DSB).""Réaumur was among the greatest naturalists of his or any age. In the breadth and range of his researches, in the patient detail of his observations, and in the brilliant ingenuity of his experiments, it would be difficult to name his equal.

‎First appearance of the famous issue of Acta Eruditorum in which the 4 solutions by the 4 most eminent mathematicians at the time, were printed together. There were in all 5 solutions to the posed problem, and Newton's solution was first printed in the Philosophical Transactions (January 1697) and reprinted here. The solution proposed by L'Hopital, not printed here, was not published until 1988.The brachistochrone problem was posed by Johann Bernoulli in Acta Eruditorum in June 1696. He introduced the problem as follows: ""I, Johann Bernoulli, address the most brilliant mathematicians in the world. Nothing is more attractive to intelligent people than an honest, challenging problem, whose possible solution will bestow fame and remain as a lasting monument. Following the example set by Pascal, Fermat, etc., I hope to gain the gratitude of the whole scientific community by placing before the finest mathematicians of our time a problem which will test their methods and the strength of their intellect. If someone communicates to me the solution of the proposed problem, I shall publicly declare him worthy of praise."" Johann Bernoulli and Leibniz deliberately tempted Newton with this problem. It is not surprising, given the dispute over the calculus, that Johann Bernoulli had included these words in his challenge:- ....""there are fewer who are likely to solve our excellent problems, aye, fewer even among the very mathematicians who boast that [they]... have wonderfully extended its bounds by means of the golden theorems which (they thought) were known to no one, but which in fact had long previously been published by others.""According to Newton's biographer Conduitt, he solved the problem in an evening after returning home from the Royal Mint. Newton: ... ""in the midst of the hurry of the great recoinage, did not come home till four (in the afternoon) from the Tower very much tired, but did not sleep till he had solved it, which was by four in the morning.""Newton send his solution to his friend Charles Montague and Montague published anonymously in the Transactions. Newton's solution, presented here in the Acta, is also anonymous. The episode did not please Newton, as he later wrote: ""I do not love to be dunned [pestered] and teased by foreigners about mathematical things ..."" After the competition Johann Bernoulli said "".... my elder brother made up the fourth of these (after Leibniz, himself and Newton), that the three great nations, Germany, England and France, each one of their own to unite with myself in such a beautiful search, all finding the same truth.""Struik (Edt.)

Wilson's paper: pp. 34-54, textillustrations, showing apparatus and 5 photographic plates, showing ionizing by Alpha-, Beta- and Röntgen- radiation).‎

‎Together with the English version - published 1912 in the Proceedings of the Royal Society - this is Wilson's main paper relating ""that the track of an ionizing particle might be made visible and photographed by condensing water of the ions which is liberated"". The first trails were obtained in 1911 where he submitted a short note of this to the Proceedings. In the offered paper he published the first tracks made by the ionizing particles of alpha, beta and Röntgen-rays. This, Wilson Cloud-Chamber, became an extremely valuable instrument of fundamental research, the discovery of the positron in 1932 and the kaon in 1963 were made by using cloud chambers as detectors.""But the whole course of the particle appears infinitely more clearly by the method invented by C.T.R. Wilson in 1911 and named after him. The radiation is allowed to enter an expansion-chamber, containing a gas saturated with water vapour. A sudden expansion of the chamber cools the gas, and cloud-drops are then formed instantly around the ions produced along the tracks of the particles. By suitable illumination these tracks can be made to stand out clearly as if they had been described by luminous projectiles. The ""Altmeister"" of modern nuclear physics, Lord Rutherford, once called the Wilson chamber ""the most original and wonderful instrument in scientific history"".""Thomson Rees Wilson (1869-1959), a Scottish physicist, is credited with inventing the cloud chamber. Inspired by sightings of the Brocken spectre while working on the summit of Ben Nevis in 1894, he began to develop expansion chambers for studying cloud formation and optical phenomena in moist air. Very rapidly he discovered that ions could act as centers for water droplet formation in such chambers. He pursued the application of this discovery and perfected the first cloud chamber in 1911. In Wilson's original chamber the air inside the sealed device was saturated with water vapor, then a diaphragm is used to expand the air inside the chamber (adiabatic expansion). This cools the air and water vapor starts to condense. When an ionizing particle passes through the chamber, water vapor condenses on the resulting ions and the trail of the particle is visible in the vapor cloud. Wilson, along with Arthur Compton, received the Nobel Prize in Physics in 1927 for his work on the cloud chamber. (Wikipedia).‎

‎First printing of an importent paper in cosmology in which Herschel's by analyzing a large number of stars, believed that he could explain the regularities he observed by assuming that the sun itself was moving toward a point in the consellation of Hercules. ""Just as Copernicus had detroned the earth as the motionless center of the universe, so Herschel detroned the sun.""(Asimov). - In this paper he tries to estimate the speed of the sun's motion.In a memoir published in 1783 Herschel had been occupied with the possibility that the sun was moving relative to the stars. ""More than 20 years later (1805, in the paper offered) Herschel took up the question again, using six of the brightest stars in a collection of the proper motions of 36 published by Maskelyne in 1790, which were much more reliable than any earlier ones, and employing more elaborate processes of calculation" again the apex was placed in the constellation of Hercules, though at a distance of nearly 30 degr. from the position given in 1783. Herschel's results were avowedly to a large extent speculative and were received by contemporary astronomers with a large measure of distrust" but a number of far more elaborate modern investigations of the same subject have confirmed the general correctness of his work.""(Berry ""A Short History of Astronomy"", p. 346.).‎

‎First printing of this importent historical paper in chemistry, in which Davy shows that electricity is capable of decomposing some alkalies, isolating two new substances and discovering potassium and sodium. Neville in his Historical Chemical Library vol. I, p.340, writes about this paper ""ONE OF THE GREAT CLASSIC RESEARCHES IN CHEMISTRY, in which Davy announced in this, his second Bakterian lecture, the isloation of metallic potassium and sodium by the electrolytic decomposition of their fused oxides.""""He (Davy) began his own electrical experiments...The results were spectacular. On October 6, 1807, the current passing through molten potash liberated a metal, which Davy called potassium. The little globules of shining metal tore the water molecule apart as it eagerly recombined with oxygen and the liberated hydrogen burst into lavender flame. Davy danced about in a delirium of joy. A week later he isolated sodium from soda.""(Asimow). The paper offered here describes these discoveries.""Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation, but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lecture to the Royal Society on November 20, 1806.(A Source Book in Chemistry p. 243). - Wheeler Gift: 2514.‎

‎First appearance of an importent paper, which contributed to the discussion of the dimension of the earth. William Mudge was appointed in 1791 to the ordnance trigonometrical survey, and became superintendent of the survey in 1798 and in that same year was also elected as a Fellow of the Royal Society. Shortly afterwards, he completed the first ever measurement of an arc of meridian stretching from Dunnose on the Isle of Wight to Clifton in Yorkshire. This was regarded as a very considerable advance in the scientific work of what had by then become the Ordnance Survey and contributed significantly to the international debate about the precise figure of the earth.‎

‎First appearance of a fundamental paper in modern optics in which Helmholtz published his discovery of the resolution limit of the microscope. He found that the limit for the difference of magnitude that we are able to distinguish plainly is in general found equal to half the wave-lenght of theparticular light employed. A further increase in optical power beyond that of the best modern instruments does not therefore seem possible.‎
