Note g — BOOK II.
Reading edition
The acute Dr. Cheyne, in his ingenious Philos. Princ. of Natural Religion, among other uses of Day and Night, saith, the Night is most proper for Sleep; because when the Sun is above the Horizon, Sleep is prejudicial, by reason the Perspirations are then too great. Also that Nutrition is mostly, if not altogether, performed in Time of Rest; the Blood having too quick a Motion in the Day: For which Reason, weak Persons, Children, &c. are nourished most, and recruit best by Sleep.
