The following are my results for the lengths of the seconds pendulum at four important stations, together with reductions to the sea-level and to the equator. In making the last reduction I have assumed the ellipticity 1/293, which is the latest result from measurements of arcs.
The differences of the figures in the last column from 0m.991 when reduced to oscillations per diem are Hoboken, +0s.01; Paris, +0s.58; Berlin -0s.59; Kew, +0s.36. The following are the residuals of former observations according to Clarke (Geodesy p. 349) New York, +0s.20; Paris, -3s.29; Kew, +2s.89. Col. Clarke has used a value of the ellipticity derived from the pendulum experiments themselves. |
The value for Hoboken is derived from [T2 Inv.], "Regular set", given on p. 318 and also on page 416 of the report of the Superintendent of the U. S. Coast & Geodetic Survey for 1876. This number is treated as explained on page 319, where in the second line from the bottom for [T2 Inv.] read [T2 Rev.]. The altitude of the Hoboken station is stated on p. 204. The numbers for the European stations are copied from page 320. |
