When at a height of 26,000 feet, Mr Glaisher could not see the column of mercury in the tube; then the fine divisions on the scale of the instrument became invisible. Shortly afterwards he laid his arm on the table, and on attempting again to use it found that the limb was powerless. He tried to move the other arm, and found that it also was paralysed.
Keep from the Doones, keep from De Whichehalse, keep from everything which leads beyond the sight of thy knowledge. I meant to use thee as my tool; but I see thou art too honest and simple. I will send a sharper down; but never let me find thee, John, either a tool for the other side, or a tube for my words to pass through."
The meat, however, no longer had the taste of fresh meat, but of such as had long lain in ice. Experiments were therefore made with carbonic acid, and these proved highly successful. The meat was placed in a cylinder of metal plate, and suspended from a rod which crossed the upper part and the lower part. A small tube serves to admit a current of carbonic acid from a Kipp's apparatus.
'Since the first notice of the discovery in the beginning of January 1860 the sun has been anxiously observed by astronomers; and the limited area around him in which the planet must be, if he is not upon the sun, has doubtless been explored with equal care by telescopes of high power, and processes by which the sun's direct light has been excluded from the tube of the telescope as well as the eye of the observer, and yet no planet has been found.
I further made little balls, and, when the sentinel was walking, blew them, through a paper tube, out of the window. Into the empty space I put my mortar and stones, and worked on successfully. I cannot, however, describe my difficulties after having penetrated about two feet into the hewn stone. My tools were the irons I had dug out, which fastened may bedstead and night-table.
The young woman smothered a smile that crept to her lips, and led Uncle John through an examination room and an operating room both vacant just now and so into a laboratory that was calculated to give a well person the shivers. Here was but one individual, a man in his shirt-sleeves who was smoking a corncob pipe and bending over a test tube.
For this reason the whole neighborhood of the joint must be heated somewhat so that there may not be stresses set up between the heated and unheated portions. Very fine capillary tubing should be blown with a rubber bulb instead of the mouth, so as not to get moisture into the tube. The rubber bulb may also be used to advantage on some of the coarser capillary tubing.
He produced the silver tube after a minute, removed the cap from one end, and shook out a piece of parchment. There was a dull crimson stain on it. "The blood of a man who tried to betray the secret!" said Gungadhura. "See-the knife of an assassin pierced the tube, and blood entered through the hole. It happened long ago." But he did not pass the tube to Dick that he might examine the knife mark.
The other four were gunners. The end globes were pierced by five large holes. They were blast holes for the rocket exhaust. Unlike the landing boats, each tube did not have its own fuel supply. One fuel tank served each globe. The pilot could direct the exhaust through any tube or combination of tubes he wished, by operating valves that either sealed or opened the vents.
A torpedo-boat built on this system may consist essentially of a series of steel tubes of large section grouped longitudinally, and divided into compartments like those of a bamboo cane. Each of these has its own small but powerful boilers and engines, and each its separate propeller at the stern. Care also is taken to place the machinery of each tube in such a position that no two are abreast.
