A few small marginal brownspots. First appearance of an remarkable paper containing an extensive set of observations on the sunspots intermingled with what Herschel called "ideas that obtruded themselves" at the time of observation."Herschel's interest in the sun was naturally stimulated by the realization that of all the stars it alone is close enough for detailled examination. he was aware of the various existing theories of the physical constitution of the sun. In a long paper published in 1795 he mentions some of them before his own observations.In 1801 in a second long paper the paper offered here in which he arranged his observations according to relevant physical questions he modified his earlier account of the sun to include in its constitution an interior layer of dark clouds not unlike our own this layer serving to shield the solar inhabitants from the exterior luminous layer. unknown

HERSCHEL, WILLIAM - DETRONING THE SUN AS THE CENTER OF THE UNIVERSEBiblio.com

On the Direction and Velocity of the Motion of the Sun and the Solar System. Read May 16 1805.

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. unknown
