EVOLUTION OF LIFE

BY

HENRY C. CHAPMAN, M.D.,
MEMBER OF THE ACADEMY OF NATURAL SCIENCES, PHILADELPHIA.


"Full fathom five thy father lies;
Of his bones are coral made;
Those are pearls that were his eyes;
Nothing of him that doth fade
But doth suffer a sea-change
Into something rich and strange."


Shakspeare.

"If we were capable of following the progress of increase of the number of the parts of the most perfect animal, as they first formed in succession, from the very first to its state of full perfection, we should probably be able to compare it with some one of the incomplete animals themselves, of every order of animals in the creation, being at no stage different from some of the inferior orders."

John Hunter.
