The book opens with a brilliant introduction by Sir Francis Younghusband, President of the Royal Geographical Society and Chairman of the Mount Everest Committee, by which the Expedition was organised. Then comes the fascinating narrative of the expedition itself, told by Col. Howard-Bury, the leader; he is followed by Mr. G. Leigh-Mallory who describes the strenuous climbing which, after many failures and disappointments, discovered what appears to be a feasible route to the summit. Mr. A. F. Wollaston, another member of the expedition, enlarges upon the remarkable fauna and flora of the Tibetan plateau and valleys, and the valuable Survey work undertaken is summarized by Major O. E. Wheeler. The Geological results are dealt with by Dr. A. M. Heron. Especially interesting, in view of the coming season's expedition, is a chapter by Prof. Norman Collie, President of the Alpine Club, upon the difficulties of mountaineering at such unprecedented altitudes and the prospects of reaching the summit of Mount Everest in 1922. The illustrations, taken from the magnificent series of photographs brought back by the expedition, are visions of beauty and grandeur, and the Maps display for the first time the topography and general features of a vast region hitherto unexplored. The hill-shaded map of the mass of Mount Everest itself on a scale of 1/100,000, will enable readers to trace the progress of the climbing parties in 1922, while showing in detail the assaults made upon the great mountain during the reconnaissance. GENERAL ASTRONOMY. By H. SPENCER JONES, M.A., B.Sc., CHIEF ASSISTANT AT THE ROYAL OBSERVATORY, GREENWICH. About 400 pages, with 103 diagrams and 24 plates. Demy 8vo. Cloth. About 21s. net. Mr. Spencer Jones, who is the leader of this year's British Eclipse Expedition to Christmas Island, has written a book covering the general aspects of Astronomy. The subject matter is treated from the scientific standpoint in the light of modern theories. At the same time the exposition is not too recondite and is such as to stimulate the general reader who is interested in the study of the Heavens. Whenever possible the argument is simplified by reference to a diagram, and throughout the book mathematics have only been used where essential for the elucidation of any problem. The book is fully illustrated and has twenty-four magnificent plates depicting comets, nebulæ, planets, etc., being the pick of the observations of the different Observatories.
