| Geological research, though it has added numerous species to existing and extinct genera, and has made the intervals between some few groups less wide than they otherwise would have been, yet has done scarcely anything in breaking down the distinction between species, by connecting them together by numerous, fine, intermediate varieties; and this not having been effected, is probably the gravest and most obvious of all the many objections which may be urged against my views.

that the remainder will stand much more distinct from each other. If the extreme forms in the genus happen to have been thus destroyed, the genus itself
→in most cases
will stand more distinct from other allied genera. The camel and the pig, or the horse and the tapir, are now obviously very distinct forms; but if we add the several fossil quadrupeds which have already been discovered to the families including the camel and pig, these forms become joined by links not extremely wide apart. The chain of linking forms does not, however, in these cases, or in any case, run straight from the one living form to the other, but takes a circuitous sweep through the forms which lived during
ages. What geological research has not

about the size of Europe from the North Cape to the Mediterranean, and from Britain to Russia; and therefore equals all the geological
