Leopold is delighted to publish this classic book as part of our extensive Classic Library collection. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. The aim of our publishing program is to facilitate rapid access to this vast reservoir of literature, and our view is that this is a significant literary work, which deserves to be brought back into print after many decades. The contents of the vast majority of titles in the Classic Library have been scanned from the original works. To ensure a high quality product, each title has been meticulously hand curated by our staff. This means that we have checked every single page in every title, making it highly unlikely that any material imperfections such as poor picture quality, blurred or missing text - remain. When our staff observed such imperfections in the original work, these have either been repaired, or the title has been excluded from the Leopold Classic Library catalogue. As part of our on-going commitment to delivering value to the reader, within the book we have also provided you with a link to a website, where you may download a digital version of this work for free.

(This book was originally published prior to 1923, and rep...)
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Franz Brunnow was born in Berlin, Germany on the 18th of November 1821.
Between the ages of eight and eighteen he attended the Friedrich-Wilhelm gymnasium. In 1839 he entered the university of Berlin, where he studied mathematics, astronomy and physics, as well as chemistry, philosophy and philology, graduating as Ph. D. in 1843.
Brunnow took an active part in astronomical work at the Berlin observatory, under the direction of J. F. Encke, contributing numerous important papers on the orbits of comets and minor planets to the Astronomische Nachrichten. In 1847 he was appointed director of the Bilk observatory, near Dusseldorf, and in the following year published the well-known Memoire sur la comete elliptique de De Vico. In 1851 he succeeded J. G. Galle as first assistant at the Berlin observatory, and accepted in 1854 the post of director of the new observatory at Ann Arbor, Michigan, U. S. A. Here he published, 1858–1862, a journal entitled Astronomical Notices, while his tables of the minor planets Flora, Victoria and Iris were severally issued in 1857, 1859 and 1869. In 1860 he went, as associate director of the observatory, to Albany, New York; but returned in 1861 to Michigan, and threw himself with vigour into the work of studying the astronomical and physical constants of the observatory and its instruments. In 1863 he resigned its direction and returned to Germany; then, on the death of Sir W. R. Hamilton in 1865, he accepted the post of Andrews professor of astronomy in the university of Dublin and astronomer-royal of Ireland. His first undertaking at the Dublin observatory was the erection of an equatorial telescope to carry the fine object-glass presented to the university by Sir James South; and on its completion he began an important series of researches on stellar parallax. The first, second and third parts of the Astronomical Observations and Researches made at Dunsink contain the results of these labours, and include discussions of the distances of the stars α Lyrae, σ Draconis, Groombridge 1830, 85 Pegasi, and Bradley 3077, and of the planetary nebula H. iv. 37. In 1873 the observatory, on Dr Brunnow’s recommendation, was provided with a first-class transit-circle, which he proceeded to test as a preliminary to commencing an extended programme of work with it, but in the following year, in consequence of failing health and eyesight, he resigned the post and retired to Basel. In 1880 he removed to Vevey, and in 1889 to Heidelberg, where he died on the 20th of August 1891. The permanence of his reputation was secured by the merits of his Lehrbuch der spharischen Astronomie, which were at once and widely appreciated. In 1860 part i. was translated into English by Robert Main, the Radcliffe observer at Oxford; Brunnow himself published an English version in 1865; it reached in the original a 5th edition in 1881, and was also translated into French, Russian, Italian and Spanish.
