(FLIGHT Photos.) nacelles, placed in accordance with latest practice slightly ahead of the leading edge, and on a level with it. This placing has been found to give the least interference drag, and to give the best all-round results. The petrol tanks, of a total capacity of 170 galls. (773 litres), giving a cruising range of 356 miles (572 km.), are placed inside the wing of the monoplane, and in the top plane of the biplane. The cockpit has accommodation for two pilots side by side, and is exceptionally roomy, as well as affording an excellent view in all important directions. A door in the back wall leads to the luggage compartment and thence to the cabin. A partition with a door opening in it divides the cabin into two compartments, of which that in front has four seats and the aft compartment six seats. The seats are by no means crowded together and are very comfortable, having good upholstery and adjustable backs. The lower half of the cabin is lined with leather, and the upper with cloth to match the leather, the whole giving a very " cozy " appearance. The space between the cabin lining and the metal wall is filled with Kapok, which assists materially in reducing engine noise. Ventilation has been well attended to, and by each seat there is a spherical louvre, universally mounted, so that the passenger can direct the air as he wishes. Warm air is conveyed from heater muffs on the exhaust pipes. The capacity of the cabin is 540 cu. ft. (15,3 m.3). The luggage compartment between cockpit and cabin is of 127 cu. ft. (3.5 m.s) capacity, while the smaller luggage and mail compartments aft of the cabin has a capacity of 100 cu. ft. (2,8 m.s). The main dimensions of the machines are: —Biplane: Length o.a., 54 ft. 8 in. (16,7 m.) ; wing span, 64 ft. (19,5 m.); height, 15 ft. 7 in. (4,8 m.); wing area, 1,037 sq. ft. (96,4 m.2). The monoplane has the same overall length as the biplane, but the height is 14 ft. (4,3 m.), the wing span 86 ft. (26,2 m.), and the wing area 1,068 sq. ft. (99,1 m.2). The following table gives some interesting comparative figures of weight items for the monoplane and biplane : THE CABIN : A partition divides it into two compart ments.
