Discusses the pros and cons of GE's proposal that [J. C.?] Schenck, a Swiss maker of optical instruments, set up a business in London. JH is not sure that JH ascended Mt. Rosa, but is certain of JH's barometric reading. Interested in GE's method of estimating air temperature.

Uncertain whether received his letter on red viper or whether the extract he sent Smith has been read at Linnean Society. Recently read of subscription for statue of Sir Joseph Banks by [Francis Leggatt] Chantrey [(1781-1841)] but ignorant whether the statue he subscribed the maximum £10 for in August 1820 has been executed yet, and does not think a second should be undertaken till the first is completed. Expresses disapprobation at Horticultural Society's "gigantic scheme" for a 33 acre experimental garden.
