An account of experiments to determine the acceleration of the Pendulum in different latitudes
Notes:

Pages extracted from this journal and bound separately within orange hard covers.

This account is partly taken from the Author's own examination of Bessel's apparatus and partly from the Transactions of the Berlin Acadamy.

"M.Bessel's memoir may be divided into two general heads: first, the measurement of the seconds pendulum at Konigsberg, by a new method, invented by himself; and, second, dissertaions and experiments on points connected with pendulum experiments generally."

Notes and annotations in ink made to the text, possibly by the Author.
