OtherInfo	Pointed out in his magnetic contributions that at certain positions in the world magnetic shoals exist which affect the compasses of vessels sailing over those shoals. Prepared the magnetic instructions for the Antarctic expedition of 1901. Brought out a liquid compass which became the standard instrument afloat, furnished with a special azimuth circle for use in torpedo-boats, destroyers, etc., all other compasses having failed to stand the vibration and motion and the gunfire in these vessels. Brought out an instrument for correcting by magnets the heeling errors. Invented the Lloyd-Creak dip and intensity apparatus, originally intended for observations afloat, which was found to be very useful on shore.
