A new variety raised by man will be a far more important and interesting subject for study than one more species added to the infinitude of already recorded species.

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.

Rudimentary organs will speak infallibly with respect to the nature of long-lost structures.
