The general impression among astronomers, after the observations of 1761 had been discussed, was that too much reliance had been placed on Delisle's method. ' Experience, ' wrote J. D. Cassini, later, in his ' Histoire du Passage de 1769, 'is our chief instructor; the fruit of its lessons indemnifies us for the value of the years they cost us. The principal end had been missed, in 1761, for want of observations in places where the durations differed sufficiently. It was essential not to experience a second time the same disadvantage.' Among the first statements published respecting the transit of 1769 was that by the ingenious Ferguson, who wrote as follows in 1762: ' On the 3rd of June, in the year 1769, Venus will again pass over the sun's disc, in such a manner as to afford a much easier and better method of investigating the sun's parallax than her transit in the year 1761 has done. But no part of Britain will be proper for observing that transit,1 so as to deduce anything with respect to the sun's parallax from it, because it will begin but a little before sunset, and will be quite over before two o'clock next morning. The apparent time of conjunction of the sun and Venus, according to Dr. Halley's tables, will be at thirteen minutes past ten o'clock at London, at which time the geocentric latitude of Venus will be full ten minutes of a degree north from the sun's centre; and therefore, as seen from the northern parts of the earth, Venus will be considerably depressed by a parallax of latitude on the sun's disc; on which account the visible duration of the transit will be .lengthened; and in the southern parts of the earth she will be elevated by a parallax of latitude on the sun, which will shorten...

Book excerpt: Throughout its early history, photography's authenticity was contested and challenged: how true a representation of reality can a photograph provide? Does the reproduction of a photograph affect its value as authentic or not? From a Photograph examines these questions in the light of the early scientific periodical press, exploring how the perceived veracity of a photograph, its use as scientific evidence and the technologies developed for printing it were intimately connected.Before photomechanical printing processes became widely used in the 1890s, scientific periodicals were unable to reproduce photographs and instead included these photographic images as engravings, with the label ‘from a photograph’. Consequently, every image was mediated by a human interlocutor, introducing the potential for error and misinterpretation. Rather than ‘reading’ photographs in the context of where or how they were taken, this book emphasises the importance of understanding how photographs are reproduced. It explores and compares the value of photography as authentic proof in both popular and scientific publications during this period of significant technological developments and a growing readership. Three case studies investigate different uses of photography in print: using pigeons to transport microphotographs during the Franco-Prussian War; the debate surrounding the development of instantaneous photography; and finally the photographs taken of the Transit of Venus in 1874, unseen by the human eye but captured on camera and made accessible to the public through the periodical.Addressing a largely overlooked area of photographic history, From a Photograph makes an important contribution to this interdisciplinary research and will be of interest to historians of photography, print culture and science.

Book excerpt: A “thrilling adventure story" (San Francisco Chronicle) that brings to life the astronomers who in the 1700s embarked upon a quest to calculate the size of the solar system, and paints a vivid portrait of the collaborations, rivalries, and volatile international politics that hindered them at every turn. • From the author of Magnificent Rebels and New York Times bestseller The Invention of Nature. On June 6, 1761, the world paused to observe a momentous occasion: the first transit of Venus between the Earth and the Sun in more than a century. Through that observation, astronomers could calculate the size of the solar system—but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Overcoming incredible odds and political strife, astronomers from Britain, France, Russia, Germany, Sweden, and the American colonies set up observatories in the remotest corners of the world, only to be thwarted by unpredictable weather and warring armies. Fortunately, transits of Venus occur in pairs; eight years later, they would have another opportunity to succeed. Thanks to these scientists, neither our conception of the universe nor the nature of scientific research would ever be the same.
