Rh our progress within recent years, the numerous discoveries and inventions for shortening time and space, increasing production, combating disease, etc., seem almost to indicate that we are scarcely more than upon the very threshold of civilization. To quote a short sentence from Tylor, "The unconscious evolution of society is giving place to its conscious development, and the reformer's path of the future must be laid out on deliberate calculation from the track of the past." If this be our understanding of scientific history, then we accept the conception of history with which we started that is, we agree that "history is the self-conscious development of society."



HEREVER the investigating minds of scientists are at work promoting the insight of man into the mysteries of Nature, wherever friends of natural philosophy are keenly alive to the importance of this comparatively new field of study, a field in which lie some of the most essential interests of modern civilization, there will be sincere and deep regret over the death of a young professor whose splendid career came to an untimely end on the first day of this year.
