In the United States, the Transit of Venus Commission sent out eight expeditions funded by Congress, one to Kerguelen, one to Hobart, Tasmania, one to Queenstown, New Zealand, one to Chatham Island in the southern Pacific, one led by James Craig Watson in Peking, one to Nagasaki in Japan, and one to Vladivostok in Russia. The eighth expedition had been intended for Crozet Island, but was unable to land there and instead made observations from Tasmania. These expeditions obtained 350 photographic plates for the 1874 transit.
