This liquid water, being at the boiling-point, has still the 100° C. of sensible heat, and hence the water in the gaseous steam form can have given up to the water at 0° C. into which it was blown, only the latent heat of gasification which was not sensible, but by virtue of which it was enabled to assume the gaseous form.
He filled his show-window with all the prints of English kings, nobles, and generals he could collect, and "then," he says, "I took down the shutters, and waited." Party-feeling reached the boiling-point when Washington retired to Mount Vernon. Mr. Adams, his successor, had none of that divinity which hedged the Father of his Country to protect him.
After thus soaking, they are well washed in fresh water, thrown into cold water, which is raised to the boiling-point, and, after remaining half an hour, taken out and again washed, Gerard, to prove that "crumpets is wholesome," ate one hundred and seventy-five pounds of the most poisonous mushrooms thus prepared, in a single month, fed his family ad libitum with the same, and finally administered them, in heroic doses, to the members of a committee appointed by the Council of Health of the city of Paris.
About one pound of sulphur having been introduced into the retort and heated to the boiling-point, the tap of the aspirator is turned on and a current of coal-gas drawn through the boiling sulphur; the hydrogen sulphide formed is washed by the water contained in B, passes on into F, and finally into the aspirator.
The writer had owned this instrument for the past ten years, but had never opportunity to test its usefulness until now. So, although it read no lower than about fifteen inches, he took it with him to observe its operation. Lastly, completing the hypsometrical equipment, was a boiling-point thermometer, with its own lamp and case, reading to 165° by tenths of a degree.
Gwynne's eyes roved over his "fair domain." Isabel, at least, was not far from its borders! "I cannot say that I am at boiling-point, but I don't fancy that matters much. I have my work cut out and I shall do it. Perhaps I shall work more disinterestedly without enthusiasm. Certainly I shall be more clear-sighted.
He was waiting at boiling-point for the opportunity to "have it out" with him: and it soon came. As the gentlemen left the dining-room and in these present days they do not, as a rule, sit long, especially when the host is a young man Percival Elster touched his brother to detain him, and shut the door on the heels of the rest. Lord Hartledon was surprised. Val's attack was so savage.
The tar is first heated in a large iron pot to boiling-point, or nearly so, and the heat is continued for about 4 hours. The pot is then removed from the fire out of doors, and while still warm, and not hot, the turpentine, mixed with the black, is stirred in. If the varnish is too thick to dry quickly, add more turpentine.
By measuring the temperature of boiling water and at the same time the temperature of the atmosphere at any high point on a mountain, and working out a computation in relation to the boiling-point temperature of a given place on the sea-level, one can obtain with accuracy the difference in height between the two points.
The temperature at this elevation, between 1 and 3 p.m., varied from 38 degrees to 59 degrees; the mean being 46.5 degrees, with the dew-point 34.6 degrees. The height I made 17,585 feet by barometer, and 17,517 by boiling-point. I tried the pulses of eight, persons after two hours' rest; they varied from 80 to 112, my own being 104.
