To complete the description, the minute structures of the vital organs are enrolled in membranous matter." These membranes are the filters of the body.

"In their absence there could be no building of structure, no solidification of tissue, nor organic mechanism.

Passive themselves, they, nevertheless, separate all structures into their respective positions and adaptations." MEMBRANOUS DETERIORATIONS.
In order to make perfectly clear to the reader's mind the action and use of these membranous expansions, and the way in which alcohol deteriorates them, and obstructs their work, we quote again from Dr.
Richardson: "The animal receives from the vegetable world and from the earth the food and drink it requires for its sustenance and motion.

It receives colloidal food for its muscles: combustible food for its motion; water for the solution of its various parts; salt for constructive and other physical purposes.

These have all to be arranged in the body; and they are arranged by means of the membranous envelopes.
