Notes:
A simplified method is given for finding the corrections for bending and stretching of a pendulum used for making an absolute determination of gravity. It appears that the correction given by Clark is incorrect and that the value of g for Teddington consequently needs an increase of about 1.7 mgal. Examination of several minor corrections mentioned by Heyl and Cook for the Washington determination shows that they mount up and that the value given by these authors also needs an increase of about 1.5 mgal. When taken in conjunction with the relative determination by Bullard and Browne, the revised values give a discrepancy of 4.7 ± 1.6 mgal., which is large enough to need attention. An independent determination is desirable.
