On a static measure for gravity.
Describes procedures, apparatus, and calculations for determining the static gravity of the earth. Thanks JH for some of his writings, and comments that JH, like Newton, has discovered the mind of the Creator and passed this on to humanity.
Notes ingenuity of JB's gravimetric balance. Astonished that it did not occur to anyone before. [Letter continues 5 Feb.:] Suggestion for improving torsion thread arrangement.
JB's solution to torsion thread arrangement is simpler and more ingenious than JH's. Enquires about details of gravimetric balance. Pendulum measurements. Density of continents. Clarification of JH's privileges as foreign associate of Institute. Death of J. B. Biot.
