    Abstract

    TEREESTEIAL MAGNETISM. THE subject of Dr. F. E. Smith's presidential address to Section A (Mathematical and Physical Science) is “Theories of Terrestrial Magnetism”. He begins by referring to early magnetic conferences and resolutions urging international co-operation, but while believing the spirit of international cooperation in terrestrial magnetism to be excellent, the question is put: “Do we make our plans sufficiently well 1” While it is to the International Union of Geodesy and Geophysics that we must look to plan lines of attack, Dr. Smith makes a plea for the adoption by man of the first class magnetic observatories of a programme including observations at the same time and with similar instruments of great sensitivity. Later in the address, when the question of simultaneity of magnetic storms is considered, this plea for similar instruments is revived, and the opinion is expressed that it should not be difficult to obtain a decisive answer to such a question by proper organisation. A point emphasised is that while each observatory should have its own particular problems and its own special methods of attacking them, and thus preserve its individuality, it should in addition have part of its equipment of an international type and part of its programme truly international in character.
