Abstract
IN the publication referred to below only the first thesis is printed. It deals with the relations between magnetic storms and solar phenomena. The thesis shows the nimbleness of mind one hopes to see in those who have taken high mathematical degrees at Cambridge, accompanied by a knowledge of terrestrial magnetism most unusual in British seats of learning. There are, it is true, researches bearing on the subjects investigated of which the author seems unaware, but his knowledge of foreign writings, including theoretical work by Kelvin, Larmor, Birkeland, Stormer, and Schuster, and observational work by Walker, Airy, Ellis, Maunder, Hale, and many others, is highly commendable. Also the attitude he adopts towards the work he criticises is generally philosophical. Thus, taking Kelvin's attempted demonstration that solar action cannot be the proximate cause of magnetic storms, Bosler points out that there are possibilities not considered by Kelvin making much smaller demands on the sun's stores of energy, and that in the light of modern knowledge no one can say what is a reasonable limit to solar expenditure. On the other hand, he recognises that Kelvin's work directed attention to a point apt to be overlooked.
