Two abortive attempts characterised the sixties of last century in France. As regards the first of these, it was carried out by three men, Nadar, Ponton d鈥橝mecourt, and De la Landelle, who conceived the idea of a full-sized helicopter machine. D鈥橝mecourt exhibited a steam model, constructed in 1865, at the Aeronautical Society鈥檚 Exhibition in 1868. The engine was aluminium with cylinders of bronze, driving two screws placed one above the other and rotating in opposite directions, but the power was not sufficient to lift the model. De la Landelle鈥檚 principal achievement consisted in the publication in 1863 of a book entitled Aviation, which has a certain historical value; he got out several designs for large machines on the helicopter principle, but did little more until the three combined72 in the attempt to raise funds for the construction of their full-sized machine. Since the funds were not forthcoming, Nadar took to ballooning as the means of raising money; apparently he found this substitute for real flight sufficiently interesting to divert him from the study of the helicopter principle, for the experiment went no further. [Pg 44] Another and later circumstantial story, with similar evidence of some fact behind it, is that of the Saracen of Constantinople, who, in the reign of the Emperor Comnenus鈥攕ome little time before Norman William made Saxon Harold swear away his crown on the bones of the saints at Rouen鈥攁ttempted to fly round the hippodrome at Constantinople, having Comnenus among the great throng who gathered to witness the feat. The Saracen chose for his starting-point a tower in the midst of the hippodrome, and on the top of the11 tower he stood, clad in a long white robe which was stiffened with rods so as to spread and catch the breeze, waiting for a favourable wind to strike on him. The wind was so long in coming that the spectators grew impatient. 鈥楩ly, O Saracen!鈥?they called to him. 鈥楧o not keep us waiting so long while you try the wind!鈥?Comnenus, who had present with him the Sultan of the Turks, gave it as his opinion that the experiment was both dangerous and vain, and, possibly in an attempt to controvert such statement, the Saracen leaned into the wind and 鈥榬ose like a bird鈥?at the outset. But the record of Cousin, who tells the story in his Histoire de Constantinople, states that 鈥榯he weight of his body having more power to drag him down than his artificial wings had to sustain him, he broke his bones, and his evil plight was such that he did not long survive.鈥? Among the first internal combustion engines to be taken into use with aircraft were those of the horizontally-opposed four-stroke cycle type, and, in every case in which these engines were used, their excellent balance and extremely even torque rendered them ideal鈥攗ntil the tremendous increase in power requirements rendered the type too long and bulky for placing in the fuselage of an aeroplane. As power increased, there came a tendency toward placing cylinders radially round a central crankshaft, and, as in the case of the early Anzani, it may be said that the radial engine grew out of the horizontal opposed piston type. There were, in 1910鈥攖hat is, in the early days of small power units, ten different sizes of the horizontally opposed engine listed for manufacture, but increase in power requirements practically ruled out the type for air work. Good of me! Had there been twice as many mails I would not have willingly missed one. But there is no doubt your letters fell off after last autumn. They were sweet, and ever welcome to me鈥攂ut they told me very little. We shall see our faders." 国产a片,伊甸园写真,6080yy理论在手机观线,台湾一级特黄大片 What are you doing there? One piece of advice given to him by his mother, when he was about to start for England, cannot but cause a smile. She was at pains to assure him that it would be unnecessary to take off his hat to every person whom he might meet in the streets of London. Henry St. George, speaking of this in later years, continues: 鈥楤ut habit is strong; and even now, when I repair to the stables for my horse, I interchange bows with the coachman and the ostlers and all the little idle urchins whom I encounter in the mews.鈥?One would have been sorry indeed to see so graceful a habit altered. It might far better be imitated. Exceeding courtesy was through life characteristic of the man, and it descended in a marked degree upon many of his descendants, notably so upon Charlotte Maria, the A. L. O. E. of literature. I am glad to make the acquaintance of any friend of yours, Oliver. We are just going in. Won't you and Mr. Bundy join us at dinner in the hotel? 鈥楽trathfieldsaye. The night was dark and cheerless. It was one of those murky November nights when one seems to see and breathe through a dusky gauze. The road from Ivy Lodge to Whitford was not lighted. At a long distance before her, Castalia saw a red, glowing speck, which she knew to be the lamp over the chemist's shop, kept by Mr. Barker, her landlord. After that, a few street lamps glimmered, and the town of Whitford had fairly begun.
