Book excerpt: "Four Albumen prints and one photoglyphic engraving of photographic views at Teneriffe of the edge of the crater. William Henry Fox Talbot made the steel plate [for Plate number 5] and 500 impressions were made from it. Negatives were made by Piazzi Smyth in 1856. This publication is one of only three or four that were ever illustrated by Talbot utilizing his photoglyphic process."--Hanson Collection catalog, p. 27.

Book excerpt: Excerpt from Astronomical Observations Made at the Royal Observatory, Edinburgh, Vol. 6: For the Year 1840 The ultimate aim of Astronomical Observations being the improvement of theory, the. Former are manifestly of no service until they have been brought, by calculation, into such a Shape as to be capable of comparison with the results of the latter. That this reduction should be effected soon after the observations have been made, was strikingly exhibited a few years ago in Professor henderson's own case, when he found, in 1839 (the epoch of bessel's discovery of the parallax of 61 Cygni), that his Cape Observations of 1832 - 3 contained within them the first really satisfactory indications of stellar parallax. Although, then, the Observatory may have temporarily ceased from amassing its usual quantity of Astronomical facts, it may still, perhaps, be considered to be as usefully employed in rendering available for the use of mathematicians, and the real promotion of astronomy, all the materials which have been accumulated during past years.

This book was released on 2016-06-27 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Astronomical Observations Made at the Royal Observatory, Edinburgh, Vol. 1: From October 1834 to December 1835 The process of reversing the instrument is conveniently and safely per formed by means of an apparatus, which allows the counterpoises to act before the pivots touch the Y's, so that no additional pressure is exerted upon them, and the instrument is replaced without the least collision. Five vertical Wires and one horizontal Wire of spider-thread are placed in the eye-end of the telescope, besides other two vertical Wires, which are fixed to the same frame, and move together by means of a micrometer screw. The Telescope has four eye-glasses, whose magnifying powers are 100, 136, 200, and 300; but 200 is the power commonly used. For faint objects, the power 136 is applied. The whole aperture of the object-glass is employed, ex cept in observations of the Sun, when it is contracted to inches, and the ih strument screened from the solar rays.
