another in Kailua, Hawaii, manned by George Forbes and Henry Glanville Barnacle. As well as observing the transit on 8 December 1874, the observers undertook a large amount of work to establish the positions, particularly the longitudes, of the three observing sites. This information was fed into the Trigonometrical Survey of the Kingdom of Hawaii, then in progress and led by Professor William DeWitt Alexander. Tupman's journal of the Honolulu Station and Forbes's journal of the Kailua (Hawaii) Station have been digitised. Charles Darwin's son, Leonard Darwin, was a photographer on the 1874 Transit of Venus Expedition to New Zealand, after which he traveled to Hawaii aboard the Mikado to meet the team in Honolulu. Publications George Biddell Airy published an Account of Observations of the Transit of Venus in Hawaii in 1881, with more than 200 pages about the expedition.
