crevice

I tapped upon the floor, but it sounded the same all over, and there was no sign of any crack or crevice.

A guttering candle was stuck in a crevice of the rocks which flanked it on each side so as to keep the wind from it and also to prevent it from being visible, save in the direction of Baskerville Hall.

Over the rocks, in the crevice of which the candle burned, there was thrust out an evil yellow face, a terrible animal face, all seamed and scored with vile passions.

The intrepid treasure-seeker walked round it, and, selecting the spot from whence it appeared most susceptible to attack, placed his lever in one of the crevices, and strained every nerve to move the mass.
