Calculations of some Observations of the Solar Eclipse on the 7th of September, 1820

The experiments above adverted to are detailed in the Philosophical Transactions for 1798; and though the greatest attention was bestowed on those parts of the inquiry relating to theweight of the solids, the method ofmeasuring them is not so fully detailed; Captain Kater, therefore, was desirous of re-investigating the latter subject before the Commissioners of Weights and Measures should make their final report. The author then proceeds to describe the state of the apparatus; and the means which he adopted in effecting this measurement of three sides of the cube gives for its content 124.1969 inches.
