Has been investigating the Cavendish experiments recently repeated by Francis Baily. Thinks G. B. Airy has neglected the resistance of the air in his mathematical theory. Would like to send an abstract of his investigations so that JH can judge their merits.
Explains combined British and foreign postage rate applied to JH's letter, which has been forwarded to France. [JH annotation on verso about actinometer.]
Sends extracts of a letter from H. C. Schumacher. Does not agree with Schumacher regarding F. W. Bessel's 'specific attraction.'
