Its heat, however, was not in proportion to its brightness; for we found that after we had ascended a few miles from the earth, it was becoming much colder, and the Brahmin had recourse to a chemical process for evolving heat, which soon made us comfortable: but after we were fairly in the great aerial void, the temperature of our machine showed no tendency to change.
F., the water of the bottom of the deep sea could not be colder than 39 deg.. But one of the first results of the careful ascertainment of the temperature at different depths, by means of thermometers specially contrived for the avoidance of the errors produced by pressure, was the proof that, below 1000 fathoms in the Atlantic, down to the greatest depths yet sounded, the water has a temperature always lower than 38 deg.
Since the outer polar regions themselves had been semi-tropical up to that time, it is very difficult to see how this will account for a freezing temperature in such latitudes as Australia and India.
But no wooden house, unless built of solid and well-fitted logs, could resist the external temperature by virtue of thickness.
It is, however, cold enough to freeze mercury, and to reduce every other substance employed as a test of atmospheric or laboratory temperatures to a solidity which admits of no further contraction.
Temperature with China and Glass.
The influence of an elevated temperature on the soluble extract of flesh is not less remarkable.
But we have no right to expect that there would be the same difference in temperature between Greenland and Central Europe as we find to-day.
This was a cheering temperature for those who had been breathing the polar air; and the influence of the north-east gale continued to increase.
It is necessary, however, to keep the fishes of tropical seas and streams in water of a very different temperature from that suited to others brought from arctic or sub-arctic climates; and this, like every other point affecting the natural peculiarities and habits of the fish, is attended to with minute and accurate care.
The coagulation of the blood may be retarded, and even prevented, by a temperature below 40 degrees F., or a temperature above 120 degrees F. The addition of common salt also prevents coagulation.
That we had actually entered the desert was apparent, and the increase of temperature during the past three days was easily explained; but whether this desert is part of that visited by Captain Sturt, or an isolated patch, has yet to be ascertained, and the only hope is that the creek will enable us to continue our course, as the nature of the country renders an advance quite impracticable unless by following watercourses.
The main rule is to secure sunlight,--hot enough to raise the water to a temperature above that of the outer air,-- to remove all dirt and floating scum, and to furnish the tank on every cloudy day with a supply of air and with motion by means of a syringe.
"Keep your temperature down, my boy.
Possibly the most notable thing that occurred through the weary weeks was the gliding of the temperature up to the unprecedented height of fifteen below.
and 12/33rds, which is the point of saturation, 226 deg.. In a steam boiler the boiling points of water containing these proportions of salt must be higher, as the elevation of temperature due to the pressure of the steam has to be added to that due to the saltness of the water; the temperature of steam at the atmospheric pressure being 212 deg.,
He admits, for example, that water is essential, that an atmosphere containing oxygen, nitrogen, aqueous vapour, and carbonic acid gas is essential, and that an abundant vegetation is essential; and these of course involve a surface-temperature through a considerable portion of the year that renders the existence of these--especially of water--possible and available for the purposes of a high and abundant animal life.
When I was in Carlsbad Caverns about a dozen years ago, the ranger told us that the temperature inside the caverns was constant.
As to catching the residuum of the process, or what we call thought,--the gaseous ashes of burned-out thinking,--the excretion of mental respiration,--that will depend on many things, as, on having a favorable intellectual temperature about one, and a fitting receptacle.--I sow more thought-seeds in twenty-four hours' travel over the desert-sand, along which my lonely consciousness paces day and night, than I shall throw into soil where it will germinate, in a year.
The temperature within the greenhouse is consequently raised, and thus the necessary warmth is maintained.
His temperature under the tongue was 97.2 deg.
The temperature thereupon quickly rises in the generator, A, while, at the same time, the combustion of the air gas produced soon reheats the chambers, B'.
If their melancholy be not inflamed, or their temperature over-hot."
In a wooden vessel the crew's quarters are better and more healthful than in iron vessels, for they are not as much affected by the temperature outside of the ship.
Two simple principles are at the root of all fire management: (1) Coal gas must be at a certain temperature before it can burn; and (2) it must have a sufficient supply of air.
Two other diagrams show the distribution of heat at the time of full-moon, one half of the curve showing the temperatures along the equator from the edge of the disc to the centre, the other along a meridian from this centre to the pole.
He even dared to take off his snowshoes that he might rub his sore ankles, but he wrapped his heavy blanket about his body, lest he take deep cold in cooling off in such a temperature after so long a flight.
