But these reflections are vain. We have to be what our birth, which decides, has made us in entering upon this world. The development of the aeroplane between 1912 and 1914 can be judged by comparison of the requirements of the British War Office in 1912 with those laid down in an official memorandum issued by the War Office in February, 1914. This latter called for a light scout aeroplane, a single-seater, with fuel capacity to admit of 300 miles range and a speed range of from 50 to 85 miles per hour. It had to be able to climb 3,500 feet in five minutes, and the engine had to be so constructed that the pilot could start it without assistance. At the same time, a heavier type of machine for reconnaissance work was called for, carrying fuel240 for a 200 mile flight with a speed range of between 35 and 60 miles per hour, carrying both pilot and observer. It was to be equipped with a wireless telegraphy set, and be capable of landing over a 30 foot vertical obstacle and coming to rest within a hundred yards鈥?distance from the obstacle in a wind of not more than 15 miles per hour. A third requirement was a heavy type of fighting aeroplane accommodating pilot and gunner with machine gun and ammunition, having a speed range of between 45 and 75 miles per hour and capable of climbing 3,500 feet in 8 minutes. It was required to carry fuel for a 300 mile flight and to give the gunner a clear field of fire in every direction up to 30 degrees on each side of the line of flight. Comparison of these specifications with those of the 1912 trials will show that although fighting, scouting, and reconnaissance types had been defined, the development of performance compared with the marvellous development of the earlier years of achieved flight was small. CHAPTER XXIII. "M. B." Two Cylinder Daimler Engine, 1897. I am sorry, madam, that I cannot inform you. The queen summoned firmness to reply: 鈥淵ou can inform the king that he will never make me consent to render my daughter miserable; and that, so long as a breath of life remains in me, I will not permit her to take either the one or the other of these persons.鈥? 鈥淪eckendorf鈥?(the embassador of the emperor) 鈥渟ometimes sends me money, of which I have great need.

Marey, in his work, La Machine Animale, credits Borelli with the first correct idea of the mechanism of flight. He says: 鈥楾herefore we must be allowed to render to the genius of Borelli the justice which is due to him, and only claim for ourselves the merit of having furnished the experimental demonstration of a truth already suspected.鈥?In fact, all subsequent studies on this subject concur in making Borelli the first investigator who illustrated the purely mechanical theory of the action of a bird鈥檚 wings.
