✦ Synopsis

IT HAS often been pointed out that magnetism has been especially difficult to understand because all of its phenomena have had to be studied statistically, and until a clearer picture of the ultimate magnetic element could be obtained progress in. magnetic theory had necessarily to be extremely slow. The great stimulation afforded to electrical theory by the discovery of the electron and the intensive study of its properties illustrates what may be expected in magnetic theory when the properties of the corresponding natural magnetic unit become accessible to investigation. Recent experimental work, to be reviewed in the theoretical part of this paper, makes it extremely probable that this magneton, as it is called, has already been directly observed. It is particularly appropriate at this time, therefore, to survey the existing state of knowledge in regard to magnetism in order to see whether we have not already a respectable body of data which may be used * Presented at a meeting held Thursday, February 28, I924.
