Strachey's scientific labours in connection with the geology, botany and physical geography of the Himalayas were considerable. He devoted much time to meteorological research, was largely instrumental in the formation of the Indian meteorological department, and became chairman of the meteorological council of the Royal Society in 1883. From 1888 to 1890 he was president of the Royal Geographical Society. In 1897 he was awarded one of the Royal Medals of the Royal Society, of which he became a fellow in 1854; and in the same year he was created G.C.S.I. He died on 12 February 1908.
