Results of Pendulum Experiments by C. S. Peirce

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.

 
At Station
At sea-level
At equator
Hoboken
0m.9932052
0m.9932074
0m.9910003
Paris
0.9939337
0.9939500
0.9910132
Berlin
0.9942399
0.9942482
0.9909865
Kew
0.9941776
0.9941790
0.9910083

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.
