Rotary Engines. [1851] It is not at all clear to me how the Statax engines described in FLIGHT convert the force of the explosions into rotary movement. In other words, the inclined rotary disc to which what one might call the big-ends of the connecting-rods are fixed does The above Interesting photograph of the Heliopolls Palace Hotel, Heliopolis, Cairo, comes from Mr. W. Oswald Watt. He points out that the wind was blowing straight over the back of his camera, and the flags are 19 yds. apart, whilst 45 to 50 yds. in the rear and immediately between them, is a fair-sized dome. He asks, can anyone explain the reason of the flags flying in opposite directions? not seem at all an efficient method of converting reciprocating into rotary movement. Perhaps someone amongst your readers better able to deal with the matter than myself would compare this com bination with the more genetally used crank-shaft, pointing out the advantages and disadvantages of each. Leeds. MECHANIC. [The fundamental principle involved in the design of the Statax engine is that the pistons are connected to a " swashplate " attached to a central shaft, and various constructions have been evolved at different times embodying this principle. As in the conventional engine, there is no tendency to rotary movement when the pistons are at the ends of their strokes, but so soon as the dead centre is passed, the thrust due to the pressure on the piston is transmitted to the inclined rotating ring to which the connecting-rods are attached, and because this ring is inclined the cylinders, &c, are caused to rotate. There is no reason, neglecting all structural considerations, why this method of converting rectilinear into rotary motion should be inferior to the usual construction.—ED.] ® ® ® ® AERONAUTICAL SOCIETY OF GREAT BRITAIN.

WITH reference to the letter quoted in Eddies last week from a visitor to Olympia who grumbled at being charged 3d, for one of the Cellon loopers, Mr. Wallace Barr subsequently received another letter, dated previous to the publication of last week's FLIGHT, in which the grumbler apologised and explained that he did not see the notice re the Desoutter Fund. By way of atonement for his meanness he sent along 12 penny stamps. The amount realised by the sale of the Cellon gliders was ,£11 IS. $d., and 5 francs. ® ® ® ® Aeronautical Patents Published.
