There was no chance for deception in the results, for the experiments were so controlled that the subject did not know until afterward of the correspondences actually reached between his states of mind and the variations in sensibility of the skin.
This slight report of the work done in one laboratory in about two sessions, involving a considerable variety of topics, may give an idea, so far as it goes, of the sort of work which experimental psychology is setting itself to do.

It will be seen that there is as yet no well-knit body of results on which new experiments may proceed, and no developed set of experimental arrangements, such as other positive sciences show.

The procedure is, in many important matters, still a matter of the individual worker's judgment and ability.

Even for the demonstrations attempted for undergraduate students, good and cheap apparatus is still lacking.

For these reasons it is premature as yet to expect that this branch of the science will cut much of a figure in education.
