Mr Maskeyne communicated that by 'equal attitudes of the Sun, taken at St Helena, January 29, and 30, and February 5th and 7th of this year; the Society's clock gained regularly 6.25 seconds, up on sidereal time, in 24 hours: that he had made a mark up on the rod of the pendulum, even with the top of the bob, the index pointing to No 3 upon the regulating nut; by which means it would be easy to adjust the pendulum to the same length here.'
