C. E. Henriod and Co., of 15, Rue du Marche, Neuilly-sur-Seine, Paris, show a well-designed 6 h.p. voiturette. The car is erected on a tubular frame, and it fully deserves its title of "The Simplon," for neatness and simplicity have been fully attained. The machine is gear driven, having three speeds and reverse. The carburetter of this firm is a speciality, as it can be used with either petrol or alcohol. The car sells at about £150. Wheel steering on an inclined pillar is provided, and the wheels are of the artillery pattern. Altogether a very fine car, and cheap at the price.
