THE CONGREGATIONAL LECTURE. SIXTH SERIES. SCRIPTURE AND GEOLOGY, REV. DR. PYE SMITH. NEW-YORK : UNIVERSITY PRESS.-J. F. TROW, PRINTER, 114 NASSAU-STREET. ON THE RELATION THE HOLY SCRIPTURES AND SOME PARTS OF GEOLOGICAL SCIENCE. JOHN PYE SMITH, D.D. F.G.S. DIVINITY TUTOR IN THE PROTESTANT DISSENTING COLLEGE AT HOMERTON. NEW-YORK: D. APPLETON & CO. 200 BROADWAY 1840. Geology, in the magnitude and sublimity of the objects of which it treats, un- doubtedly ranks, in the scale of the sciences, next to Astronomy. Sir John F. W. Herschel. There is a knowledge which creates doubts that nothing but a larger knowledge can satisfy ; and he who stops in the difficulty will be perplexed and uncomfortable for life. Mr. Sharon Turner. PREFACE The following lectures were prepared and delivered, by the appointment of the Committee of the Congrega- tional Lecture, under some peculiarity of circumstances. The appointment was unexpected, and the notice unavoid- ably short. Several parts therefore, and those referring to subjects of the greatest importance, were treated in a manner too brief, and indeed extemporaneously : but to the kind and attentive audience the promise was given that, if the publication should take place, the author would supply those deficiencies. This he has endeavoured to do, partly by filling up the portions which, in the delivery, were but sketched, and partly by adding Notes, both on the immediate pages, and in a Supplementary Appendix. The reader will perceive that numerous citations are introduced. For this, no apology is requisite : and, in- deed, so richly interesting are the most of those passages, that it would have been a wrong to the subject and to the reader to have withheld them. Another circumstance proves their importance and even necessity. The facts which are the basis of geological reasonings can be known to the majority even of well educated persons, 1* VI PREFACE. only by testimony ; as, in the greater number of instan- ces, they are to the author himself. To bring forwards, therefore, the statements of the most competent authori- ties, in their own words, is due to the right position of the subject and to the satisfaction of the reader. Should it be objected, that some of those citations contain reas- onings and opinions, besides statements of fact ; the re- ply is that they are the reasonings and opinions of men who thoroughly understood the grounds upon which they are built ; and that, therefore, the inferences which such men have seen to be just, are entitled to stand in the next line of authority to their testimony as eye-witnesses and labourers in the great field. It involves no disrespect to the multitude of pious and intelligent persons, to say that they cannot form an independent opinion upon many subjects in Natural Philosophy. It is no dishonour to accept the conclusions of Newton and his followers, though we confess ourselves unable to read the Principia. ADVERTISEMENT. (by the committee of the congregational library.) The
