If one will follow the lines of thought as crystallized in the works on medicine and metaphysics which have survived the lapse of ages, he will observe that a parallelism exists between these two great branches of inquiry, and that progress or development in one, is accompanied by advancement in the other. The great period of illumination in physiology which was ushered in by Harvey’s dem- onstration of the movement of the blood, had its complement in the long stride made by modern re- search in nervous function and the office of the brain —of which research the Oxford professor, Willis; was one of the chief promoters. When science had fairly emerged from the maze of medieval controversy, and chemistry, astronomy, physiology, and mental philosophy had been estab- lished upon firm principles universally recognized, then the wonderful development of the eighteenth and nineteenth centuries was begun. In this devel- opment we perceive the influence of Temperament, and it is no difficult task for the physiologist, particu- larly if he be learned in the works of Gall and Spurz- heim, to signalize the several effects which peculiar constitutional states have had in determining the course of individual effort and in molding results.
