Book excerpt: Excerpt from Outline of the Course of Geological Lectures Given in Yale College This outline of my course, of geological lectures, is to be regarded, as a skeleton, furnished indeed with some of the principle muscles; but, destitute of the color and finish, of a perfect form. To my pupils, to whom it has particular reference, it may serve both as a guide and a review, and should it prove, in any degree, useful to others, I shall be gratified. It is intended as an outline of the philosophy of geology according to the best views, which I have been able to take of the subject. Those who may peruse it, will, however, do me the justice to believe, that in the progress of the lectures, full details are given, and numerous specimens of rocks exhibited, both Foreign and American, in the order proposed, with ample descriptions of their mechanical and chemical constitution their organized remains, and the order of their arrangement and connexion, and some subjects are discussed which are not even mentioned in this general sketch. As it is the fashion of the day, to attribute almost every thing in the earth to igneous agency, I shall probably be thought to be behind the present state of opinion, while I maintain, that the chemical affinities, through the medium of aqueous solutions of the great chemical agents as well as of water itself, have also produced important effects in the early arrangements of the planet. If Werner attributed too much to these causes, may there not be danger, at this day, of vibrating to the opposite extreme? It is indeed already proved, that igneous agency has been vastly more extensive than was formerly believed, and it is probable that evidence of this kind will accumulate, as the researches of well instructed geologists are directed, more and more, to this important topic.
