The increased temperature of the afternoon is therefore not so much due to the accumulation of caloric from the sun's rays, as to the passage of a heated current of air derived from the much hotter regions to the westward. It would be interesting to know how far this N.W. diurnal tide extends; also the rate at which it gathers moisture in its progress over the damp regions of the Sunderbunds.
In obedience to the demands of an imperious, ever-rising, thermometer, we reduced our rig to the least possible articles consistent with decency and the regulations of the Service which latter, by the way, discriminates not between the caloric of the north pole and that of the equator. Just at this time, we encountered a phenomenon of frequent occurrence in this region, namely, water-spouts.
It may be easily conceived that the emission and loss of caloric is more rapid in masses with black crusts than in those which abound in laminae of silvery mica.
"And is it in the hope of that notable discovery you have studied chemistry, electricity, and magnetism? Again I say, Silly boy!" Margrave did not heed my reply. His face was overcast, gloomy, troubled. "That the vital principle is a gas," said he, abruptly, "I am fully convinced. Can that gas be the one which combines caloric with oxygen?" "Phosoxygen?
Sir D. Brewster imagines that the non-luminous rays of caloric, which form a constituent part of the solar light, are emitted by the dark nucleus of the sun; whilst the visible coloured rays proceed from the luminous matter by which the nucleus is surrounded.
My basket of fat used to prove very attractive all through the cold weather, when, I suppose, these tiny birds need the caloric it supplies; they always left off coming as soon as the days were warm and insects plentiful. Pigeons possess a great deal more individuality of character than any one would suppose who has only seen them in flocks picking up grain in a farmyard, like domestic fowls.
They had very little wood, and what they had was used sparingly. Once or twice a tree, fixed in the ice, gave them additional fuel; but they were obliged chiefly to count on oil. A small fire was made at night to cook by; but it was allowed to go out, the tent was carefully closed, and the caloric of six people, with a huge lamp with three wicks, served for the rest of the night.
But when he went out, she placed on his table a tract, entitled "The Furnace Seven Times Heated," which tract the captain considerately handed to his engineer, supposing it to be a circular on intensified caloric. Year after year the captain laid up for repairs, and put up with Mrs. Simmons. Year after year he was jolly, genial, chivalrous, generous, but not what good Mrs.
'Oh, I understood the messenger to say I might come, replied the untruthful politician. 'You see, it's not a personal matter, but the very biggest sensation that ever went under the ocean on a cable, and I thought Well, you know, I felt I had done you quite unintentionally a mean trick on board the Caloric and this was kind of to make up for it, don't you know.
Fortunately, however, the caloric developed by the Reiset and Regnault process for purifying the air, raised the internal temperature of the Projectile a little, so that, with an expenditure of gas much less than they had expected, our travellers were able to maintain it at a degree capable of sustaining human life.
