Abstract I have the pleasure to inclose a provisional abstract of the results of Capt. Basevi’s observations with his pendulums during the past field season. Though provisional, it will probably be found to agree very closely with the final results, which will be deduced as soon as the corrections for buoyancy, temperature, &c. are finally known. Already these experiments are beginning to throw light on the subject of Himalayan attraction; for the observations clearly show that the force of gravity is less than it should be theoretically at the stations in the vicinity of the Himalayas, and that the difference between theory and practice diminishes the further the station is removed from the Himalayas.
