Taking {232} the longitude of Cadiz as 6° 19' 07" west of Greenwich, the figures given in the table are obtained.

Madrid, en la Imprente real, Ano de 1809: 2 vols., large 8°; vol. 1, pp. 57-60. My attention was directed to this work by Dr. Dall, who owns the only copy I have seen.] The data from which the various determinations made previous to 1874 were obtained have not been published. The observations made by Messrs. Dall and Baker, of the U. S. Coast and Geodetic Survey, are published in full in the annual report of that Survey for 1875, already referred to. The observations made by myself last summer as a part of the work of an expedition sent to Mount St. Elias by the National Geographic Society and the U. S. Geological Survey, from which the height and position of the mountain have been computed, are as follows:
