His house is full of scientific instruments a really good camera, a fine aneroid barometer, several thermometers, including self-registering maximum and minimum, etc., etc. All seem excellent in quality, but I could not learn that he makes any use of them, except the camera. The cura, and the judge deride his possession of the instruments, doubting whether he knows how to use them.
She'd jumped up half an inch in about two seconds, wiggled round some, and then come back to normal. You can see the curve yourself if you ask Fraser to show you the self-registering barograph. Some doin's, I tell you!" He nodded his head with an air of importance.
It seemed to me that it could be used for observations far from the meridian. The iron part was hollow, so that the clock was inside, as was the azimuth circle, and thus space was saved. "They have a wind and rain self-register, and a self-registering barometer, marking on a cylinder turned by a clock, the paper revolving once an hour.
Now the glacier itself was to be the main subject of investigation, and he took with him a variety of instruments for testing temperatures: barometers, thermometers, hygrometers, and psychometers; beside a boring apparatus, by means of which self-registering thermometers might be lowered into the heart of the glacier.
You have seen self-registering instruments which recorded how many revolutions they had made and what work they had done, so the manufacturer could come days after and look at the instrument and find just how many revolutions had been made, or how much work had been accomplished. So the human mind is a self-registering instrument, and it records all its past movements.
An improved instrument was added that recorded temperatures on a self-registering roll, all fluctuations, and the highest and lowest temperatures, wind-pressures, all variations in humidity, temperature, and air pressure as well as the directions and the velocity of the wind for periods of seventy days and more.
He wanted graven records, so that no wiseacre like Harris, here, could say: 'Oh, the thing never moved. You were all hypnotized! In effect, he said: 'They tell us that a cold wind blows from the cabinet. I will put a self-registering thermometer in the cabinet and see. They say tables weighing forty pounds have been lifted. All I ask is that the bulb of a self-registering manometer be pressed.
The top gained, a space was quickly selected and cleared, and a simple hut of flat stones begun, while the Captain unpacked his box. It contained a barometer, a maximum and minimum self-registering thermometer, wet and dry bulb, also a black bulb thermometer, a one-eighth-inch rain-gauge, and several other instruments.
The identical instant at which the effusion of light was observed was recorded by an abrupt and strongly marked deflection in the self-registering instruments at Kew."
It is evident, however, that until arrangements are consummated for recording systematic observations on the variations of the level of this Lake, we cannot expect that its Seiches will be detected. Of course, self-registering gauges would give the most satisfactory results; but any graduated gauge, systematically observed, would soon furnish evidence of the phenomenon.
