discoveries: both are intimately acquainted with the evidence adduced by the geologist, and entertain no doubt whatever regarding what it establishes; but though in the main friendly to at least the moral sanctions of the New Testament, both virtually set aside the Mosaic cosmogony; the one (Mr. Babbage) on the professed grounds that we really cannot arrive with any certainty at the meaning of that old Hebrew introduction to the Scriptures in which the genesis of things is described; and the other (Mr. Powell) on the assumption that that introduction is but a mere picturesque myth or parable, as little scientifically true as the parables of our Saviour or of Nathan the seer are historically so. Now, I cannot think that the anti-geologists are quite in the place in which they either ought or intend to be when engaged virtually in making common cause with either of these latter classes.[35] Be this as it may, however, it may be not uninstructive, and perhaps not wholly unamusing, to examine what the claims really are of some of our later anti-geologists to be recognized as the legitimate and qualified censors of geologic fact or inference. It will be seen, that in the passage which I have quoted from Turrettine, the theologian, in three of his five divisions, restricts himself to the theologic province, and that when in his own proper sphere even his errors are respectable; but that in the two concluding divisions he passes into the province of the natural philosopher, and that there his respectability ceases for the time, and he becomes eminently ridiculous. The anti-geologists,--men of considerably smaller calibre than the massive Dutch divine of the seventeenth century,--also enter into a field not their own. Passing from the theologic province, they obtrude into that of the geologist, and settle against him, apparently after a few minutes' consideration, or as mere special pleaders, questions on which he has been concentrating the patient study and directing the laborious explorations of years. And an exhibition by specimen of the nonsense to which they have in this way committed themselves in their haste, may not be wholly uninstructive. But I must defer the display till another evening. I shall do them no injustice; but I trust it will be forgiven me should I exhibit, as they have exhibited themselves, a class of writers to whose assaults I have submitted for the last fourteen years without provocation and without reply.
