Rh schedules varied so widely. No attempt was made to keep the order of experiments rigidly the same for all. Convenience and economy of time necessarily determined the order to a great extent. In general, however, the simple sensory and motor tests were given in the early part of the series, and the intellectual tests in the latter part. The questions on personality usually came last, The taste and smell experiments had to be scattered through most of the periods, since only a few at a time could be performed without fatigue. The entire series was applied to fifty subjects, twenty-five men and twenty-five women.

The experiments fell into seven groups, dealing respectively with motor ability, skin and muscle senses, taste and smell, hearing, vision, intellectual faculties, and affective processes. One chapter of this monograph is devoted to each group. A list of the experiments under each group will be found at the beginning of each chapter. At the end of each chapter there is a comparison of results with those of other investigators, and a general summary. The numbers in parentheses used in the summaries of other experimental work and throughout the text, refer to the bibliography at the end of the volume. The bibliography pretends to completeness only in its enumeration of the experimental researches bearing on the problem, and even here there are doubtless omissions, although it is hoped that all the important papers are mentioned. Whenever for the sake of brevity a dogmatic statement is made to the effect that there are no data on a certain point, or only such data as are quoted, the qualification, so far as the author knows, is to be understood.
