The chapter on balances and pendulums, written by Capt. Kater, is of special importance, as it inclmles the author's 



important investigations and discoveries on the subject, e.g. his Balance and Compensation Pendulum. 



Captain Kater's scientific career began with his share in the triansjulation of the Malabar and Coromandel coasts in 

 1802. He afterwards prepared standard measures for the Russian Government, and thenceforward pursued astronomy, 

 and also devoted much time to pendulum experiments by the adoption of the ' knife-edge ', and produced a seconds-pendulum 

 of extraordinary delicacy, which served in the establishment of our present national system of standard weights and 

 measures.
