Her husband shrugged his shoulders and walked out of the room. As he left the house he was met at the garden-gate by a bright-eyed, consumptive-looking lad, in shabby working clothes, who touched his cap, and held out a paper to Algernon. "What do you want?" asked the latter. "Mr. Gladwish, sir. His account, if you please, sir." 鈥楾he first boiler which I made was constructed something on the Herreshof principle, but instead of having one simple pipe in one very long coil, I used a series of very small and light pipes, connected in such a manner that there was a rapid circulation through the whole鈥攖he tubes increasing in size and number as the steam was generated. I intended that there should be a pressure of about 100 lbs. more on the feed-water end of the series than on the steam end, and I believed that this difference in pressure would be sufficient to ensure a direct and positive circulation through every tube in387 the series. The first boiler was exceedingly light, but the workmanship, as far as putting the tubes together was concerned, was very bad, and it was found impossible to so adjust the supply of water as to make dry steam without overheating and destroying the tubes. Mr C. M. Manly, working under Professor Langley, had, by the summer of 1903, succeeded in completing an engine-driven machine which under favourable atmospheric conditions was expected to carry a man for any time up to half an hour, and to be capable of having its flight directed and controlled by him. 2019中文字字幕在线不卡_中文字幕AV "No, it was not atropin," returned Craig, giving the drug its more scientific name. "It was physostigmine." 鈥榃e have had such an amusing breakfast. Lord Glenelg was here. And he and Mamma have been making us laugh so,鈥攈e with his quiet jokes, and dear Mamma with her na?vet茅. Mamma very freely criticised Sir R. Peel鈥檚 and Lord John Russell鈥檚 manner of speaking, to the great amusement of our guest, who threw out a hint that he might inform, and that Mamma had compromised herself. 鈥淚t would be rather awkward,鈥?he observed, 鈥渋f I were to sit beside Sir Robert this evening, after what has passed鈥? and when he heard that Sir Robert was not to be present, he hinted that Mamma was in the same danger in regard to Lord John Russell. 鈥淏ut if I tell him that he opens his mouth too wide,鈥?said Lord Glenelg, 鈥渉e may think I mean that he eats too much!鈥? 390 Daimler, from 1882 onward, devoted his attention to the perfecting of the small, high-speed petrol engine for motor-car work, and owing to his efforts, together with those of other pioneer engine-builders, the motor-car was made a success. In a few years the weight of this type of engine was reduced from near on a hundred pounds per horse-power to less than a tenth of that weight, but considerable further improvement had to be made before an engine suitable for use with aircraft was evolved. Algernon paused with his hand on the lock of the door leading to his private room. He kept his hand there, and scarcely turned his head as he asked, "How so?"
