Sleep is to a man what winding up is to a clock. Schopenhauer.

Sleep lingers all our lifetime about our eyes, as night hovers all day in the boughs of the fir-tree. Emerson.

Sleep no more, / Macbeth does murder sleep. 45 Macb., ii. 2.

Sleep seldom visits sorrow; when it doth, / It is a comforter. Tempest, i. 1.

Sleep, that knits up the ravell'd sleave of care, / The death of each day's life, sore labour's bath, / Balm of hurt minds, great nature's second course, / Chief nourisher in life's feast. Macb., ii. 2.

Sleep, that sometimes shuts up sorrow's eye. Mid. N.'s Dream, iii. 2.

Sleep, the antechamber of the grave. Jean Paul.

Sleep the sleep that knows not breaking, / Morn of toil, nor night of waking. Scott.

Slight not the smallest loss, whether it be / In love or honour; take account of all: / Shine like the sun in every corner: see / Whether thy stock of credit swell or fall. George Herbert.

Slippery is the flagstone at the great house door. Gael. Pr.
