On this point he expresses himself with perfect clearness: "The motive power of a fall of water depends on its height and on the quantity of liquid; the motive power of heat depends also on the quantity of caloric employed, and on what might be called in fact, what we shall call the height of fall, that is to say, the difference in temperature of the bodies between which the exchange of caloric takes place."
The third afternoon of their hiding, Jolly Roger decided upon action. This afternoon all of the caloric guns of an unclouded sun had seemed to concentrate themselves on the gigantic rock-pile. Though it was now almost sunset, a swirling and dizzying incandescence still hovered about it.
In its usual acceptation, it merely means the effect excited on the organs of sensation by a hot body. But as this must be produced by a power in the hot body independent of sensation, that power is what chemists understand by the word heat: and to distinguish between the effect and its cause, the term caloric has been substituted.
As we are therefore often unable to control heat-production, the best we can do is to abstract the caloric from the body whenever it becomes so excessive as to threaten serious results.
While such great names were occupied in discussing this question, physical inquirers of a less ambitious stamp laid experimentally the solid basis of a future mathematical theory of heat. Some established, that the same quantity of caloric does not elevate by the same number of degrees equal weights of different substances, and thereby introduced into the science the important notion of capacity.
Why, in short, when a girl has labored through a profound chemical work, and listened to courses of chemical lectures, should she come to domestic life, which presents a constant series of chemical experiments and changes, and go blindly along as without chart or compass, unable to tell what will take out a stain, or what will brighten a metal, what are common poisons and what their antidotes, and not knowing enough of the laws of caloric to understand how to warm a house, or of the laws of atmosphere to know how to ventilate one?
'My God, George! he cried, 'what is the matter with you? What has happened? Tell me! Wentworth gazed in front of him with glassy eyes for a moment, but did not answer. Then his head dropped again in his hands, and he groaned aloud. There was one man on board the Caloric to whom Wentworth had taken an extreme dislike. His name was Fleming, and he claimed to be a New York politician.
Thenceforth the thunderbolt ceased to exist, save in poetry, country houses, and the most rural circles; even the electric fluid was generally relegated to the provincial press, where it still keeps company harmoniously with caloric, the devouring element, nature's abhorrence of a vacuum, and many other like philosophical fossils: while lightning itself, shorn of its former glories, could no longer wage impious war against cathedral towers, but was compelled to restrict itself to blasting a solitary rider now and again in the open fields, or drilling more holes in the already crumbling summit of Mount Ararat.
As the temperature of the atmosphere, observed at the port of Orotava by M. Savagi, was 22.8 degrees, the decrement of caloric was one degree every 94 toises. This result perfectly corresponds with those obtained by Lamanon and Saussure on the summits of the Peak and Etna, though in very different seasons.
Sir Humphrey Davy demonstrates that gas not to be, as Lavoisier supposed, caloric, but light, combined with oxygen; and he suggests, not indeed that it is the vital principle itself, but the pabulum of life to organic beings." "Does he?" said Margrave, his, face clearing up. "Possibly, possibly, then, here we approach the great secret of secrets.
