all the wonders of history, it is idle to consider it at all. But investigations in hypnotism still go on, and may do much in the twentieth century to carry the world yet further from the realm of the miraculous. In a third field science has won a striking series of victories. Bacteriology, beginning in the researches of Leeuwenhoek in the seventeenth century, continued by O. F. Muller in the eighteenth, and developed or applied with wonderful skill by Ehrenberg, Cohn, Lister, Pasteur, Koch, Billings, Bering, and their compeers in the nineteenth, has explained the origin and proposed the prevention or cure of various diseases widely prevailing, which until recently have been generally held to be "inscrutable providences." Finally, the closer study of psychology, especially in its relations to folklore, has revealed processes involved in the development of myths and legends: the phenomena of "expectant attention," the tendency to marvel-mongering, and the feeling of "joy in believing." In summing up the history of this long struggle between science and theology, two main facts are to be noted: First, that in proportion as the world approached the "ages of faith" it receded from ascertained truth, and in proportion as the world has receded from the "ages of faith" it has approached ascertained truth; secondly, that, in proportion as the grasp of theology Upon education tightened, medicine declined, and in proportion as that grasp has relaxed, medicine has been developed. The world is hardly beyond the beginning of medical discoveries, yet they have already taken from theology what was formerly its strongest province--sweeping away from this vast field of human effort that belief
