"It was found that it (Ohkotz) is 25° off of the meridian of Peking, which the observations of P. Gaubil placed in 113° fifty-odd minutes from Paris, so that it closely approximates the 139° which we have found it to be from Bering's observations. This determination does not differ much from the result of some astronomical observations, which, as I learn from China, M. de l'Isle, now in Russia, contemplated using in order to ascertain approximately the longitude of Kamtchat. The observation upon which I place the most dependence, and which likewise gives the greatest difference, is of an eclipse of the moon of February 25, 1728, of which the end was observed on the west coast of Kamtshat in latitude 52° 46' N., Sirius having an altitude of 19° 18' to the west, wherefrom M. de l'Isle calculated that the true time answered to 6h. 52m. p.m. "This eclipse, the end especially, fell throughout Europe in the daytime, but having been observed at Carthagena, West Indies, by D. Jean Herrera, where it ended at 3h. 34m. a.m., a difference of 8h. 42m. is deduced between the meridians of Carthagena and the coast of Kamtshat." It is thus evident that Bering observed an eclipse of the moon in Kamshatka, and that the observations came into the hands of M. d'Anville. A. W. G. JANUARY 21, 1892. {231} HEIGHT AND POSITION OF MOUNT ST. ELIAS. BY ISRAEL C. RUSSELL. (_Laid before the Board of Managers December 11, 1891_.) The height and position of Mount St. Elias have been measured several times during the past century with varying results. The measurements made prior to 1891 have been summarized and discussed by W. H. Dall, of the U. S. Coast and Geodetic Survey.[1] The various results obtained are shown in the following table. With the exception of the position determined by Malaspina and the measurements of 1891, they are copied from Dall's report. [Footnote 1: Rep. of the Superintendent of the U. S. Coast Survey for 1875, pp. 157-188.] _Height and Position of Mount St. Elias_.
