This book was released on 2017-11-26 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Discussion of the Magnetic and Meteorological Observations, Vol. 1: Made at the Girard College Observatory, Philadelphia, in 1840, 1841, 1842, 1843, 1844, and 1845; Investigation of the Eleven Year Period in the Amplitude of the Solar Diurnal Variation and of the Disturbances of the Magnetic Declination It is proposed in the present paper to investigate the law of the eleven year period, or as it is more frequently called, the decennial period, there being yet an uncertainty as to its precise length. It is supposed to have some direct or_ indirect connection with the solar spot period, which, according to late investigations by Prof. R. Wolf,2 is said to exhibit corresponding disturbances. The discussion is a contribution towards the determination of the epoch of the occurrence of a minimum (as to number and magnitude) in certain phases of the magnetic variations and disturbances, corresponding to a minimum in the solar spot period. The method of reduction is substantially the same as that adopted by General Sabine, and explained in his discussion of the Toronto and Hobarton3 observations. This longitude depends on that of Cambridge observatory, for which 411 44 has been adopted. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Discussion of the Magnetic and Meteorological Observations, Vol. 3: Made at the Girard College Observatory, Philadelphia, in 1840, 1841, 1842, 1843, 1844, and 1845 In January, 1841, the Lloyd instrument was replaced by a re ecting vertical force magnetometer, made at my suggestion by Mr. J. Saxton. The bar of this instrument was two feet and one inch in length, two inches wide in the middle, one and a half near the ends, tapering to nothing at the ends, and a quarter of an inch thick. The magnet was of steel and hardened as perfectly as the maker could effect. By means of a ball moving on a fine screw, its equilibrium could be changed. The mirror projected outside the box, and the motion of the bar was observed by means of a telescope. At the top of the box was a piece of plate glass through which a thermometer (of Francis' make) could be read. For further particulars see p. Vii, of the preface to volume I of the record. For some time (between three and four months) after being put up, the bar lost considerably of its magnetic force, and after being in use four months, a movement of the adjusting ball upon the screw was required for placing the readings again near the middle of the scale. By this adjustment, the sensibility of the apparatus was not interfered with. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
