THE illustrations in preparation for the Third Volume of this work having rendered a large page necessary, the present volume, and the new edition of the First Volume are arranged in a corresponding form.

They ought not to have appeared in a detached form, but the writer could not expect his argument to be either remembered with accuracy, or reviewed with patience, if he allowed years to elapse between its sections.
