Ken, I forgot to say, this table of contents is from the third, 1802, edition of the Requisite Tables. "Price Five Shillings, stitched in blue Paper." My copy is hardcover, sewn up in sail cloth, and has been much used. The book's a bit smaller than the present Nautical Almanac. To continue: General Introduction; concerning the Instruments and Observations P. 1-3. Explanation of the Tables P. 3-14. Problem 1, To find the Latitude of a Ship at Sea, from the Observed Meridional Altitude of the Sun's Limb P. 14-15. Problem II, To find the Latitude of a Ship at Sea, from the Observed Meridional Altitude of a Fixed Star P. 15-16. Problem III, To find the Latitude of a Ship at Sea, from the Observed Meridional Altitude of the Moon's Limb P. 16-17. Problem IV, To find the Latitude of a Ship at Sea, having the Latitude by Account, Two Observed Altitudes of the Sun, the Time elapsed between the Observations measured by a common Watch, and the Sun's Declination P. 17-25. Problem V, To correct the Latitude found by the last Problem, after One Computation P. 25-30. Problem VI, The Latitude and Longitude of a Place, and the Observed Altitude of the Sun's Limb being given, together with the Time of Observation nearly, to find the Apparent Time at that Place P. 30-31. Problem VII, The Latitude and Longitude of a Place, and the observed Altitude of a known Fixed Star being given, together with the Time of Observation nearly, to find the Apparent Time at that Place P. 32-33. Problem VIII, The Apparent Time, the Ship's Latitude and Longitude, and the Sun's Declination being given, to find its Apparent Altitude P. 33-34. Problem IX, The Apparent Time, and the Latitude and Longitude of the Ship being given, to find the Apparent Altitude of any known Fixed Star P. 34-35. Problem X, The Apparent Time, and the Latitude and Longitude of the Ship being given, to find the Apparent Altitude of the Moon's center P. 35-36. Problem XI, Having the apparent, or observed Distance of the Moon from the Sun or a Fixed Star, together with the Observed Altitude of each, and the Moon's Horizontal Parallax, to find their true Distance P. 37-46. Problem XII, To find the Longitude of a Ship at Sea, by Observations of the Moon's Distance from the Sun, and their Altitudes, taken at the same Time; the Latitude of the Ship, and its Longitude by Account, being also known P. 47-49. Problem XIII, To find the Longitude of a Ship at Sea, by Observations of the Moon's Distance from a known Fixed Star, and their Altitudes, taken at the same Time; the Latitude of the Ship, and its Longitude by Account, being also known P. 49-57.
