Page 626 - On the 2d observations were begun. The first station was made near the old Transit of Venus station, occupied by the English party in 1874, and reoccupied by myself in 1887 while determining astronomical latitudes for the Hawaiian Government.
Page 623 - With the aid of a map and verbal instructions at the Government Survey Office in Honolulu, Mr. Preston was able to find the spot where the great navigator, Cook, had his observatory in 1779, and the magnetic instruments were placed practically in the same locality. Hawaii Island...
