There is no place in Russia, Archangel and Astrakhan included, where the thermometer does not rise in summer nearly to 86° Fahr.
There is no difficulty in observing the temperature of the surface of the sea on board ship, the only precautions required being to draw the water in a bucket which has not been heated in the sun in summer or exposed to frost in winter, to draw it well forward of any discharge pipes of the steamer, to place it in the shade on deck, insert the thermometer immediately and make the reading without delay.
The temperature drops so rapidly that a month later, about October the oth on the middle Urals and November the 15th throughout Russia, the thermometer ceases to rise above the freezing-point.
The mean winter reading of the thermometer is 54.7, and accompanied as this is by clear skies and an absence of snow, the season is both pleasant and invigorating.
A thermometer thrust into the middle of Walden on the 6th of March, 1847, stood at 32º, or freezing point; near the shore at 33º; in the middle of Flint's Pond, the same day, at 32º; at a dozen rods from the shore, in shallow water, under ice a foot thick, at 36º.
In 1889, at Windsor, prizes were awarded for a fruit and vegetable evaporator, a paring and coring machine, a dairy thermometer, parcel post butter-boxes to carry different weights, and a vessel to contain preserved butter.
The temperature of the pond water which had stood in the room where I sat from five o'clock in the afternoon till noon the next day, the sixth of March, 1846, the thermometer having been up to 65º or 70º some of the time, owing partly to the sun on the roof, was 42º, or one degree colder than the water of one of the coldest wells in the village just drawn.
1903, 200, p. 105) carefully examined the behavour of a constant volume gas thermometer filled with helium.
Thus at high temperatures a helium thermometer is of no special advantage.
On the mainland, and more especially on the eastern slope, the temperature is cooler, the thermometer seldom rising above 93° in the shade, and falling at night below 70°.
In the same way, whilst in the plains and hills round Naples snow is rarely seen, and never remains long, and the thermometer seldom descends to the freezing-point, 20 m.
In the districts bordering on the coast the thermometer seldom falls below 37°; and only for a few moments and at long intervals has it been known to rise as high as 105°.
The total quantity of liquid employed need not in general exceed half a litre if a sufficiently delicate thermometer is available.
At Singapore and Batavia the thermometer very rarely falls below 70°, or rises above 90°.
The average daily variation of the thermometer is from 67° to 83° F.
The earliest form of testing instrument employed for this purpose was that of Giuseppe Tagliabue of New York, which consists of a glass cup placed in a copper water bath heated by a spirit lamp. The cup is filled with the oil to be tested, a thermometer placed in it and heat applied, the temperatures being noted at which, on passing a lighted splinter of wood over the surface of the oil, a flash occurs, and after further heating, the oil ignites.
The heat in May and June is very great, and the thermometer rises considerably above too F.
And - 10.2° respectively; while at Yakutsk and Verkhoyansk the thermometer occasionally falls as low as - 75° and - 85° F.
While in summer the thermometer goes up to 97° F., in winter it descends to 19.5°.
The temperature of Cutch during the hot season is high, the thermometer frequently rising to roo° or 105° F.; and in the months of April and May clouds of dust and sand, blown about by hurricanes, envelop the houses, the glass windows scarcely affording any protection.
June, July and August are the hottest months, the thermometer often reaching 85° or 90°, though the heat of the day is to some degree compensated by the freshness of the nights.
To the establishment of this new conception the improvement and general use of the clinical thermometer gave invaluable advantages.
De Haen, and, in the United Kingdom, George Cleghorn (1716-1789) of Dublin and James Currie (1756-1805), carried on the use of the thermometer in fevers; and on the continent of Europe in later years F.
By these, and other instruments of precision, such as the thermometer, of which we have already spok en, the eminently scientific discipline of the measurement of functional movements, so difficult in the complex science of biology, has been cultivated.
In the shade and off the ground the thermometer rarely rises above 80° F.
Although the bore of the thermometer-tube is exceedingly small, it is made in the same way as ordinary tube.
At higher elevations the rainfall is no doubt heavier; Manzoni mentions that at Sana there was constant rain throughout August and September 1878, and that the thermometer during August did not reach 65°.
Be provided with a tubulure, or opening, which permits the charging of the retort, and also the insertion of a thermometer b.
If N be the length of the unheated mercury column in degrees, t the temperature of this column (generally determined by a small thermometer placed with its bulb at the middle of the column), and T the temperature recorded by the thermometer, then the corrected temperature of the vapour is T-+o 000143 (T - t) N (T.
- The general observation that under a constant pressure a pure substance boils at a constant temperature leads to the conclusion that the distillate which comes over while the thermometer records only a small variation is of practically constant composition.
But the variation of the thermometer in winter and summer being considerableas much as 72 F.
Hecker took the opportunity of a voyage from Hamburg to La Plata, and in 1904 and 1905 of voyages in the Indian and Pacific Oceans to determine the local attraction over the ocean by comparing the atmospheric pressure measured by means of a mercurial barometer and a boiling-point thermometer, and obtained results similar to Scott Hansen's.
To), for the purpose of interposing at pleasure the prism it in the axis of the reading micrometer; this enables the observer to view the graduations on the face of the metallic thermometer TT (composed of a rod of brass and a rod of zinc).
Which Bilbao is situated; the others, which are numerous, are merely large mountain streams. The climate is rather inclement and variable; but the thermometer seldom drops below freezing point, nor does snow fall frequently in winter except on the highest summits.
