Our classifications will come to be, as far as they can be so made, genealogies; and will then truly give what may be called the plan of creation.

The rules for classifying will no doubt become simpler when we have a definite object in view.

We possess no pedigree or armorial bearings; and we have to discover and trace the many diverging lines of descent in our natural genealogies, by characters of any kind which have long been inherited.
