Not illustrated. 1858 edition. Excerpt: ...the upper station, h' = 600.95 T' = 21.3 t' = 21.3 Barometer at the level of the sea, h = 763.15 T = 25.3 t = 25.3 Table I. gives the corresponding numbers, Difference, Table II. gives for T'--T, Difference, JL. 2 (i + t') = 1.897 X 93.2, Sum, 2074.3 Table III. gives for mean latitude of 21," + 4.3 Table IV. gives for decrease of gravitation in the vertical line, -f-6.0 Hence altitude of Guanaxuato above the ocean, 2084.6 Measurement of the height of Mont Blanc, August 29, 1844.

Barometer atone metre below the summit, A'=424.05 T' =--4.2 t' =--7.6 Barometer of the Observatory of Geneva, A = 729.65 T = 18.6 t = 19.3 Table I. gives for numbers corresponding to; Difference, Table II. gives for T'--T, Difference, Difference, Table III. gives for the mean latitude of 46, Difference, Table IV. for decrease of gravitation in the vertical line Table V. for the elevation of the lower station, Sum, Elevation of the lower barometer above the ocean, Hence elevation of upper barometer above the ocean, Finally, height of the summit of Mont Blanc above the ocean, 4814.5 TABLE I.--Giving A = 18336 X log. H or A argument H or in Millimetres. TABLE II. Correction For Difference Of Temperature Of Attached Tukkmometles This Table supposes the scale to be of brass from the top to the cistern. If it were of glass or of wood, the argument T'--T ought to be diminished at the ratio of 54 to 62. In calculating the formula of Laplace, we begin by reducing the barometers to the same temperature by means of the following formula: H = h'-f-/i' ( Z--, ) Table II. saves this trouble, and gives, in metres, the correction due to the difference of temperature of the barometers. TABLE III. Correction For Decrease Of...show more
