inhabitants of each area are related to the inhabitants of the nearest source whence immigrants might have been derived. We see this in →nearly all the plants and animals of the Galapagos archipelago, of Juan Fernandez, and of the other American

The fact, as we have seen, that all past and present organic beings →constitute one grand natural system, with

On these same principles we see how it is, that the mutual affinities of the →species and genera within each class are so complex and circuitous. We see why certain characters are far more serviceable than others for classification;— why adaptive characters, though of paramount importance to the
