"We have now a record of 713 experiments, and I recently set myself the task of classifying them into the 4 classes of successful, partially successful, misdescriptions, and failures. I endeavoured to work it out in what I thought a reasonable way, but I experienced much difficulty in assigning to its proper column each experiment we made. This, however, is a task which each student of the subject will be able to undertake for himself according to his own judgment. I do not submit my summary as a basis for calculation of probability. A few successful experiments of a certain kind carry greater weight with them than a large number of another kind; for some experiments are practically beyond the region of guesses.... "The following is a summary of the work done, classified to the best of my judgment:-- FIRST SERIES. Key A. = Nothing perceived. B. = Complete. C. = Partial.
