Neste artigo, apresentamos uma tradução comentada para o português do texto “Observations on vision” (1793), de Thomas Young (1773-1829), seu primeiro trabalho publicado nas Philosophical Transactions da Royal Society. Nesse texto, Young discutiu algumas teorias e ideias sobre a acomodação visual existentes até sua época. Após apontar diversas falhas nessas teorias, ele propôs a sua, baseada na existência de uma musculatura no cristalino responsável especificamente por esse mecanismo. A tradução é precedida por três seções, em que aspectos da história da anatomia ocular e das teorias anteriores para a acomodação visual são abordados, a fim de contextualizar a leitura do material traduzido.Thomas Young’s studies on visual accommodation: an analysis of the episode and a commented Portuguese translation of his “Observations on vision”(1793)AbstractIn this paper, we present a commented Portuguese translation of Thomas Young’s (1773-1829) “Observations on vision” (1793), his first published paper in Royal Society’s Philosophical Transactions. In this article, Young discussed some previous theories and ideas on visual accommodation up to his days. After pointing out the flaws of these theories, he proposed his own: muscles in the crystalline lens were responsible for this mechanism. The translation is preceded by three sections in which we comment on aspects of the history of eye anatomy and of the previous theories for visual accommodation, in order to contextualize the reading of the translated material.Keywords: Visual accommodation; Optics; Vision; Thomas Young; Light. 

George Gabriel Stokes was one of the most significant mathematicians and natural philosophers of the nineteenth century. Serving as Lucasian professor at Cambridge he made wide-ranging contributions to optics, fluid dynamics and mathematical analysis. As Secretary of the Royal Society he played a major role in the direction of British science acting as both a sounding board and a gatekeeper. Outside his own area he was a distinguished public servant and MP for Cambridge University. He was keenly interested in the relation between science and religion and wrote extensively on the matter. This edited collection of essays brings together experts in mathematics, physics and the history of science to cover the many facets of Stokes’s life in a scholarly but accessible way.


Richard Nichols, The Diaries of Robert Hooke, The Leonardo of London, 1635-1703 . Lewes, Sussex: The Book Guild, 1994, Pp. 185, £15.00. ISBN 0- 86332-930-6. Richard Nichols is a science master turned historian of science who celebrates in this book Robert Hooke’s contributions to the arts and sciences. The appreciation brings together comments from Hooke’s Diaries , and other works, on each of his main enterprises, and on his personal interaction with each of his principal friends and foes. Further references to Hooke and his activities are drawn from Birch’s History of the Royal Society, Aubrey’s Brief Lives , and the Diaries of Evelyn and of Pepys. The first section of the book, ‘Hooke the Man’, covers his early years of education at home in Freshwater, at Westminster school and at Christ Church, Oxford, where he soon joined the group of experimental philosophers who set him up as Curator of the Royal Society and Professor of Geometry at Gresham College, Bishopsgate. Hooke’s domestic life at Gresham College is described - his intimate relationships with a series of housekeepers, including his niece, Grace Hooke, and his social life at the College and in the London coffee houses.


On 24 May 1820 a manuscript entitled ‘A Mathematical Inquiry into the Causes, Laws and Principal Phenomena of Heat, Gases, Gravitation, etc.’ was submitted to Davies Gilbert for publication in the Philosophical Transactions of the Royal Society . The author was John Herapath (1790-1868), and his article included a comprehensive (if somewhat faulty) exposition of the kinetic theory of gases. Sir Humphry Davy, who assumed the Presidency of the Royal Society on 30 November 1820, became primarily responsible for the fate of the article and wrote several letters to Herapath concerning it. After it became clear that there was considerable opposition to its publication by the Royal Society, Herapath withdrew the article and sent it instead to the Annals of Philosophy , where it appeared in 1821 (1). Herapath’s theory received little notice from scientists until thirty-five years later, when the kinetic theory was revived by Joule, Krönig, Clausius, and Maxwell. The incident is significant in the history of physical science because it illustrates an important distinction between the two doctrines concerning the nature of heat—the kinetic and the vibration theories—a distinction which is often forgotten because of the apparent similarity of both doctrines as contrasted with the caloric theory. It also throws some light on the character of early nineteenth century British science, both in and out of the Royal Society.


In the Royal Society archives there is a collection of drawings of Aloes and other plants, made by two of the great botanical artists of the eighteenth century - Georg Dionysius Ehret and Jacob van Huysum. Although the Manuscripts General Series Catalogue records this manuscript only as a ‘Volume of 35 botanical paintings by Georg Dionysius Ehret’ of unknown provenance, the manuscript catalogue of the Arundel and other manuscripts, said to be the work of Jonas Dryander (1748-1810), provides the first clue linking these drawings to the two artists, and to the important collection of Aloes growing at that time in the Society of Apothecaries Physic Garden at Chelsea'. The history of the commissioning of the drawings is told briefly in the Journal Books of the Royal Society, and in the Minutes of Council, but the significance of these lovely and important drawings has been almost completely overlooked.

I have for some time entertained an opinion, in common with some others who have turned their attention tot he subject, that a good series of observations with a Water-Barometer, accurately constructed, might throw some light upon several important points of physical science: amongst others, upon the tides of the atmosphere; the horary oscillations of the counterpoising column; the ascending and descending rate of its greater oscillations; and the tension of vapour at different atmospheric temperatures. I have sought in vain in various scientific works, and in the Transactions of Philosophical Societies, for the record of any such observations, or for a description of an instrument calculated to afford the required information with anything approaching to precision. In the first volume of the History of the French Academy of Sciences, a cursory reference is made, in the following words, to some experiments of M. Mariotte upon the subject, of which no particulars appear to have been preserved. “Le même M. Mariotte fit aussi à l’observatoire des experiences sur le baromètre ordinaire à mercure comparé au baromètre à eau. Dans l’un le mercure s’eléva à 28 polices, et dans Fautre l’eau fut a 31 pieds Cequi donne le rapport du mercure à l’eau de 13½ à 1.” Histoire de I'Acadérmie, tom. i. p. 234. It also appears that Otto Guricke constructed a philosophical toy for the amusement of himself and friends, upon the principle of the water-barometer; but the column of water probably in this, as in all the other instances which I have met with, was raised by the imperfect rarefaction of the air in the tube above it, or by filling with water a metallic tube, of sufficient length, cemented to a glass one at its upper extremity, and fitted with a stop-cock at each end; so that when full the upper one might be closed and the lower opened, when the water would fall till it afforded an equipoise to the pressure of the atmo­sphere. The imperfections of such an instrument, it is quite clear, would render it totally unfit for the delicate investigations required in the present state of science; as, to render the observations of any value, it is absolutely necessary that the water should be thoroughly purged of air, by boiling, and its insinuation or reabsorption effectually guarded against. I was convinced that the only chance of securing these two necessary ends, was to form the whole length of tube of one piece of glass, and to boil the water in it, as is done with mercury in the common barometer. The practical difficulties which opposed themselves to such a construction long appeared to me insurmount­able; but I at length contrived a plan for the purpose, which, having been honoured with the approval of the late Meteorological Committee of this Society, was ordered to be carried into execution by the President and Council.


It is my pleasant duty to welcome you all most warmly to this meeting, which is one of the many events stimulated by the advisory committee of the William and Mary Trust on Science and Technology and Medicine, under the Chairmanship of Sir Arnold Burgen, the immediate past Foreign Secretary of the Royal Society. This is a joint meeting of the Royal Society and the British Academy, whose President, Sir Randolph Quirk, will be Chairman this afternoon, and it covers Science and Civilization under William and Mary, presumably with the intention that the Society would cover Science if the Academy would cover Civilization. The meeting has been organized by Professor Rupert Hall, a Fellow of the Academy and also well known to the Society, who is now Emeritus Professor of the History of Science and Technology at Imperial College in the University of London; and Mr Norman Robinson, who retired in 1988 as Librarian to the Royal Society after 40 years service to the Society.
