The Henry Potez type XV Observation Biplane, fitted with a 370 h.p. Lorraine-Dietrich engine.
A new Junkers' three-seater: This machine, to which reference was made in FLIGHT recently, is a departure from Junkers' practice in having the wing placed on top instead of low down on the fuselage. The cabin has accommodation for two passengers, and as the engine is a Siemens of 60 h.p. only, the machine is using but 20 h.p. per occupant, which should give very economical running.
COMMERCIAL AVIATION IN AUSTRALIA: The Western Australian Airways, Ltd., Depot at Perth, and some of the machines - Bristol Tourers and Avro.

CZECHO-SLOVAK CONCEPTION OF COMMERCIAL AEROPLANES: These three scale models represent designs either actually in course of construction or contemplated by the Military Aircraft Factory, to the designs of Ingenieur Smolik. 1 shows the "S.15," with four Hispano-Suiza engines placed in tandem in the wings. The propeller efficiency of the pusher screws aft of such a deep wing seems a somewhat doubtful quantity. In 2 is shown the model of a three-engined machine, in which the tractor engine in the fuselage is a Napier "Lion," while the two pushers are B.M.W. engines of 220 h.p. each. 3 shows a seven-engined design, but this has, we believe, been abandoned as being too ambitious.
