Havelock Ellis

An early scientific treatise on the physiology and psychology of sleep, first read as a series of papers before a psychological society and later reworked into this monograph. Argues from observation and case reports toward a theory of what stays awake while we sleep.

Edward W. Cox

A study of sleep as a mental habit rather than a purely physical need, aimed at readers who sleep badly. Combines practical advice on rest and relaxation with reflections on what the sleeping mind is doing.
