Summary:

GG's book [Journals of Two Expeditions of Discovery in the North-West and Western Australia, 2 vols. (London: Boone, 1841)] is creating a sensation in London. Pleased to learn from it of the range of mountains named after JH. Hopes GG will carry out some study into the Aboriginal dialects. Standards of weight and measure should be sent to all Colonies. Important to have a magnetic survey of all colonized and colonizable parts of Australia.
