Nautical Science and Astronomy have advanced hand in hand; and to perfect the former as much as possible the United States Government established the Naval Observatory.

3. The observatory was built and furnished with various astronomical and philosophical instruments, and a corps of professors were appointed to watch the movements of the heavenly bodies, and to make such observations and experiments[312] as would enable them to determine many unsettled questions which relate to the science of navigation; and incidentally to another great govern............
