4. A historical and descriptive narrative of the Mammoth Cave of Kentucky, including explanations of the causes concerned in its formation, its Atmospheric conditions, its Chemistry, Geology, Zoology, etc.; with full scientific details of the eyeless Fishes; by W. STUMP NORWOOD, M.D. 225 pp. 12mo, with illustrations. Philadelphia, 1870. (J. B. Lippincott & Co.)-All future visitors to the Mammoth Cave will have occasion to thank Dr. Norwood for the service he has rendered the tourist. The book contains several interior views of the cave, which give some idea of the wonders within, although a very inadequate one. They should be supplemented by a good map of the extensive windings of the cavern. The author estimates the extent of the various avenues and mazes of the Mammoth Cave at over one hundred and fifty miles. An instrumental survey would probably shorten this assumed distance, but we know from our own wanderings in it that its extent is immense. The chapter on the eyeless fishes is made up mostly from the writings of Agassiz and Wyman, and presents the facts on the subject in an attractive form, well adapted to instruct and interest the general reader.

5. Tent life in Siberia, and Adventures among the Koraks and other Tribes in Northern Kamtchatka and Northern Asia; by GEORGE KINNAN. 425 pp. 12mo, with a map. New York, 1870. (G. P. Putnam & Sons, London; S. Low, Son and Marston). -A very readable and instructive narrative of travel in a little known region of the globe, is this neat volume of Mr. Kinnan's. The costly and disastrous enterprise of the Western Union Telegraph Company, designed to establish electrical communication between America and Asia through Kamtchatka and Northern Asia, has been by no means fruitless in scientific interest. Already Messrs. Whymple and Dall have given us instructive and valuable contributions upon their wanderings in British Columbia and Alaska. Mr. Kinnan makes no claim to any special devotion to scientific investigation, but his narrative gives a clear and lively account of the physical and social conditions of a country rarely visited, and full of curious interest. His volume well repays perusal, and is obviously the work of a good observer and careful historian, who is never tedious, and has the agreeable art of carrying his reader along with him.

6. Report of the Superintendent of the U. S. Coast Survey, showing the progress of the Survey during the year 1867. 344 pp. 4to, with 28 maps.-This volume, besides the Report of the Superintendent, Prof. Peirce, contains, among the articles in its Appendix, a Report on Transatlantic determination of Longitude, by Dr. B. A. Gould; on comparison of Meters, by Dr. F. A. P. Barnard and M. Tresca; on a new form of Reflector for geodetic signals, by J. E. Hilgard; on the Tides and Currents of Hell Gate, by Henry Mitchell; on Soundings in the Gulf Stream, by H. Mitchell; on the Fauna of the Gulf Stream, by L. F. Pourtales; on Alaska Territory, by G. Davidson; obituary of Alexander Bache.

7. Treatise on the power of Water as applied to drive Flour Mills and to give motion to Turbines and other Hydrostatic

Engines; by JOSEPH GLYNN, F.R.S., member of the Institute of Civil Engineers of London, etc. 3d ed., revised and enlarged. 162 pp. 12mo, with numerous illustrations. New York, 1869. (D. Van Nostrand).-This is a popular and practical treatise on water as a motive power. It is simple in its explanations and mathematics, and is well illustrated.

8. Archives of Science and Transactions of the Orleans Co. Society of Natural Sciences.-This first number of the Archives of a new Natural History Society, at Newport, Vermont, contains the following papers: On the characters and customs of the Pawnees, by Rev.

9. The American Entomologist and Botanist.-This St. Louis Journal will be suspended during the year 1871, to be resumed with the commencement of the following year.

10. Geology and Revelation, or the Ancient History of the Earth, considered in the light of Geological facts and Revealed religion, with illustrations; by the Rev. GERALD MOLLOY, D.D., Prof. Theol. Roy. Coll. St. Patrick, Maynooth. 380 pp. 12mo. New York, 1870. (G. P. Putnam & Sons.)-A handsome American edition of the excellent work noticed at page 151 of this volume.
