The Nautical Magazine for 1843 includes fascinating early data sets on ocean currents, and several 'bottle charts' compiled from them.

This book describes the history and development of navigating instruments. Before satellites these were used to measure the altitude of the sun and stars above the horizon, to determine the ship's position at sea. The book also contains a catalogue of 347 mariner's astrolabes, cross-staffs, backstaffs, and octants, sextants and artificial horizons.

The 1844 Nautical Magazine includes articles on the building of Birkenhead Docks, Navy provisions and the bullet that killed Nelson.
