V._Suggestion._--Space permits only the mention of another research, which, however, should not be altogether omitted, since it illustrates yet other problems and the principles of their solution.

This is an investigation by Messrs.

T.and H.,[10] which shows the remarkable influence of mental suggestions upon certain bodily processes which have always been considered purely physiological.

These investigators set out to repeat certain experiments of others which showed that if two points, say those of a pair of compasses, be somewhat separated and put upon the skin, two sensations of contact come from the points.
But if while the experiment is being performed the points be brought constantly nearer to each other, a time arrives when the two are felt as only one, although they may be still some distance apart.
