422 chief of an expedition to determine whether Asia and America were connected by land. The expedition went overland through Siberia to Kamchatka, where ships were built and the explorations begun. Bering reached the strait that bears his name, and thus proved that Asia and America were separated by water. Soon after his return he proposed a second expedition to chart the northwestern coast of America, then an unknown land, and the northern coast of Siberia. This should lead to the establishment of trade with the American colonies, and also make known a way by water from Russia around to Japan. Bering reached the coast of Alaska in 1741, and died on the way back. For a long time jealousy discredited his results, and the chief object of the present volume is to establish the value of his discoveries. The book also tells the story of the obstacles which he overcame in his expeditions. It is accompanied by two folded maps, and has an introduction by Lieutenant Frederick Schwatka.

The literature of cycling has been increased by a book bearing the title Cycling Art, Energy, and Locomotion, written by Robert P. Scott (J. B. Lippincott Company, $2). It is largely devoted to explaining the mechanical principles involved in the action of the cranks, wheels, springs, bearings, gears, etc. It includes also brief discussions of the injuries charged against cycling, the bicycle for ladies, English and American workmanship in cycles, aluminum in cycle construction, and the application of steam and electricity to cycles. A second part of the volume comprises extracts from the patent specifications of a large number of velocipedes, cycles, and nondescript vehicles, with the inventors' drawings of the machines and riders, and humorous comments by the author. Many of these machines are astonishing contrivances, and perhaps none more so than the flying-machine, patented March 5, 1889, which is introduced at the end.
