May 18th. The Mortification of a member . . .is based on the Law of Degeneration. The useless member here is not cut off, but simply relieved as much as possible of all exercise. This encourages the gradual decay of the parts, and as it is more and more neglected it ceases to be a channel for life at all. So an organism "mortifies" its members.
