It should be observed that thus far we have encountered a group of replies from persons who, as a group, are remarkably healthy, normal, and fairly free from worry. Particularly, worry does not seem to be a vice of professors, as only 8 per cent. confess to it. About 17 per cent. of them say they need more physical exercise than they get, which is mostly walking. There is also a gratifying unanimity as to good appetite, simple diet, and absence of need for artificial means of inducing sleep.
APPENDIX E
BIBLIOGRAPHY
It is surprising how little has been written about Sleep, and what a small part of what has been written is worth reading. Perhaps the best book, certainly the most exhaustive, is Marie Manacéïne’s “Sleep,” which contains a full but disorderly Bibliography.
Except in the case of American works, which might easily have escaped Marie Manacéïne’s attention, I have not tried to go further back than that Bibliography, as she was most industrious in research; I have only cut out from her list what seemed the more obsolete or needless works. But with the help of A. T. Craig and others, I have carried it, as far as may be, down to date.
