Abstract
IN a paragraph on the last number of Terrestrial Magnetism, in NATURE of March 1, p. 421, I notice the following sentence: “Dr. Lüdeling investigates graphically the phenomenon of the diurnal variation of the earth's magnetism for eleven stations with the aid of von Bezold's vector diagrams.” These diagrams are curves in which the radius vector represents in magnitude and direction the resultant of the disturbing forces to which we may attribute the diurnal variation of the horizontal component of the earth's magnetic force at any particular station.
