Excerpt from Psychological Review, Vol. 2 It would hardly be possible for any one man to-day to succeed in understanding all of Helmholtz' investigations equally well. But each will find a peculiar satisfaction in recalling the special impulse which he has experienced in his own department through the inspiration Of Helmholtz. And the representatives of Physiological Psychology should feel themselves impelled to such a retrospect, since it is to that science that Helmholtz dedicated himself at the zenith of his power. The two works which have largely rendered his name illustrious, and from which there has proceeded an incalculable stimulus to other men, belong to our especial province. Without in the least depreciating the thoroughly original and fundamental contributions Of E. H. Weber, Fechner, and Lotze, nevertheless it must be acknowledged that these two works, both on account of the scientific con sequences which have followed them, and of the general and wide-spread knowledge of their contents throughout the scientific world, have more than all others served to bridge the gulf between Physiology and Psychology - a bridge across which thousands of other men now constantly come and go.
