.1 History of Aeronautics. By E. C. \'ivr\N and \V. 

 LocKWooD Marsh. (Collins, 30s.) 

 The historj- of aeronautics, which has developed so 

 amazingly in the lifetime of all of us, has now been set 

 down within the compass of a single volume. The authors 

 give a detailed account of how the aeroplane, the balloon, 

 and the dirigible of to-day came into being, and trace their 

 development until August of last year. Part I deals 

 with the aeroplane, and an idea of the treatment may 

 best be given by mentioning the titles of some of the 

 chapters : Lilienthal and Pilcher ; American Gliding 

 Experiments ; S. P. Langley ; The Wright Brothers ; 

 First Fliers in England ; Rheims, and After ; the Channel 

 Crossing ; London to Manchester ; the War Period ; 

 1919-20. Part II deals with progress in design, and is 

 contributed by Col. Lockwood Marsh. Part III deals 

 with dirigibles, the commercial airship, and balloons. 

 Part IV deals with engine development. The compilation 

 of all this matter has been judiciously and carefully carried 

 out, and a good book is the result. Its value is increased 

 by the variety and number of the illustrations. It will 

 bring back to readers pleasant recollections of pre-war 

 years, and some of the few pleasant ones of war-time.
