" Bristol " Jupiter radial air-cooled aero engine in France to the well-known Gnome and Le Rhone Engine Co. The announcement is of more than ordinary interest as an indication of the high estimate formed in regard to the " Bristol " engines by the French aviation experts. The fact that the " Bristol " Jupiter and " Bristol " Lucifer engines are the only two air-cooled engines which have ever satisfied the strenuous conditions of the British Air Ministry Type Tests has created a great impression in Continental aviation centres. The selling rights for the " Bristol " Jupiter engine in France and many of the countries of Europe have also been ceded to the Gnome and Le Rhone Co. LIEUT.-COL. C. F. HITCHINS, D.S.O., M.I.Mech.E., who recently resigned the appointment of General Manager to Agricultural and General Engineers, Ltd., has joined Sir \V. G. Armstrong, Whitworth and Co., Ltd. " By AIR TO EVERYWHERE " is the title of an extremely useful and attractive booklet issued by the Lepaerial Bureau of 27, Piccadilly. The first issue for the present season has just been published, and contains the time-tables of the more important air lines in Europe, together with fares and other information useful to air travellers. At the end of the book will be found a sketch-map which gives an excellent idea of the number and extent of the air lines at present in opera tion. Excellent little sketches of some of the new machines in regular use on the various air lines illustrate the book, and altogether the publication is one which all intending travellers by air should make a point of securing. Copies can be had on application at the office of the Lepacrial Bureau, 27, Piccadilly (under the Piccadilly Hotel). ft ft ft ft PUBLICATIONS RECEIVED The Professional Photographer, May, 1922.
