It is a crustacean which has left the free, independent life common to its family, and is living as a parisite, or pauper.

Not using its organs for self-help, they one by one have disappeared,—legs and other members,—until there is left a shapeless mass, with only the stomach and organs of reproduction left. This tendency to parasitism was transmitted to its de- scendants, until there is set up an irresistible hereditary tendency; and the Sacculina stands in nature as a type of degradation through parasitism, or pauperism. I propose to trace the history of similar degradation in man. It is no pleasant study, but it may be relied upon as fact. It is no isolated case. It is not peculiar to Indiana.
