The membranous labyrinth is lodged within the bony labyrinth and has the same general form; it is, however, considerably smaller and is partly separated from the bony walls by a quantity of fluid, the perilymph. In certain places, it is fixed to the walls of the cavity. The membranous labyrinth contains fluid, the endolymph, and on its walls the ramifications of the acoustic nerve are distributed. Within the osseous vestibule, the membranous labyrinth does not quite preserve the form of the bony cavity, but consists of two membranous sacs, the utricle, and the saccule. The membranous labyrinth is also the location for the receptor cells found in the inner ear.

"And she went, and came and gleaned in the field after the reapers: and her hap was to light on the portion of the field belonging unto Boaz, who was of the family of Elimelech. And, behold, Boaz came from Bethlehem, and said unto the reapers, Jehovah be with you. And they answered him, Jehovah bless thee. Then said Boaz unto his servant that was set over the reapers, Whose damsel is this? And the servant that was set over the reapers answered and said, It is the Moabitish damsel that came back with Naomi out of the country of Moab:" Ruth 2:3-6 ASV
<p>Illustration of Ruth gleaning grain in the fields of Boaz. She is on her knees at the feet of Boaz, who walks with a staff and a dog behind him. His servant tells him about Ruth. Four men and women, also gleaning, watch in the background. A small town and some trees are pictured in the background.
