A NEW EXPOSITION OF THE LEADING FACTS OF GEOLOGY. Including a Disquisition upon the Origin and Formation of Petroleum and Coal. By Gideon Frost. New York : The Trow & Smith Book Manufacturing Company, 48 and 50 Greene street. Under this heading has recently been published a small work professing to controvert many of the geological theories which Ehave received the assent of the most noted geologists of this country and of Europe. It moreover theorizes upon subjects* respecting which celebrated geologists have either not essayed a theory, or respecting which there is no general agreement among them. We cannot coincide with the conclusions of the author, although we have been interested in his views. SUBMARINE BLASTING IN BOSTON HARBOR, MASS. Removal of Tower and Corwin Rocks. By John G. Foster, Lieutenant-Colonel of Engineers, and Brevet Major-General U. S. A. With Illustrations. New York : D. Van Nos-trand, 23 Murray street, and 27 Warren street.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
