 ... various liquids and transparent solids (thirteen in number, including spring, rain, and salt water; Spanish and Rhenish wine; vinegar; spirits of wine; oils and glass). The angle of incidence is 30 in each case; also the specific gravity of each substance is given. Then he discusses the reason why refraction takes place. Promises to write on the Rainbow; but will merely say at present that it is to be explained by the reflection on the concave superficies and the refraction at ...

... much as I am," said Stacy, "that this good fortune is rather crowding to us three alone. For myself, I know," he continued, with a backward glance towards a blanketed, covered pile in the corner of the cabin, "that I feel rather oppressed by—by its specific gravity, I calculate—and sort of crampy and twitchy in the legs, as if I ought to 'lite' out and do something, and yet it holds me here. All the same, I doubt if anybody will come up—except from curiosity. Our luck has made ...

... with the hand, and the process of rotation renewed until the whole of the sand is taken away, and the gold alone remains. It is found in very minute scales, and, unless I had been assured to the contrary, I should have taken it to be mica, for, knowing the gold to be of greater specific gravity than the sand, I imagined that a stream of water would remove the latter and leave the former; but here the practice is to remove the whole of the sand by the hand. This process was, no doubt, a profitable ...

... full, and, piling up his raiment on the floor, jumped in. Displacing a large quantity of water, equal to his own bulk, he thereupon solved the question of specific gravity, and, forgetting his bill, forgetting his clothes, he sailed up Sixteenth street and all over Syracuse, clothed in shimmering sunlight and a plain gold ring, shouting "Eureka!" He ran head-first into a Syracuse ...

... should be for the worse. We are floating on a sea of beneficence, in which it is impossible for us to sink. But though one could not easily drown in the Dead Sea, one might starve. And when goodness is of too great specific gravity it is impossible to get on in it or out of it. This is disconcerting to one of an active disposition. It is comforting to be told that everything is completely good, till you reflect that that is only another way of saying that nothing can be made any better, and that there ...

... among the rarest of fossils, due, no doubt, to their aerial habits removing them from the ordinary dangers of flood, bog, or ice which overwhelm mammals and reptiles, and also to their small specific gravity which keeps them floating on the surface of water till devoured. Their remains were long confined to Tertiary deposits, where many living genera and a few extinct forms have been found. The only birds yet known from the older rocks are the toothed birds (Odontornithes) of the Cretaceous ...

... accumulated from c to e. Now, water in motion can exert this levelling power on similar materials more easily than air, for almost all stones lose in water more than a third of the weight which they have in air, the specific gravity of rocks being in general as 2 1/2 when compared to that of water, which is estimated at 1. But the buoyancy of sand or mud would be still greater in the sea, as the density of salt-water ...

... less than four stone. Now, if we reduce four stone into drachms we shall find the condor is 14,336 times as heavy as the humming-bird. What an amazing disproportion of weight! Yet by the same mechanical use of its wings the condor can overcome the specific gravity of its body with as much ease as the little humming-bird. But this is not all. We are informed that this enormous bird possesses a power in its wings, so far exceeding what is necessary for its own conveyance through the air, that it can take up and fly away with a whole sheer in its talons, ...

... parenchyma of the lungs, that organ commences the formation of carbon; thus increasing the amount originally deposited. Dr Brockmann sets forth, as grounds for this view, that "if the parenchyma of the lungs were filled with carbonaceous dust, their specific gravity ought to be increased; but this is not the case. A completely melanosed lung swims in water, both as a whole and when cut into parts." It is very evident from these remarks, that the author has not seen the disease as it is exhibited in the third division of morbid ...

The gas itself was analyzed; and its heating power calculated, from its composition, as 617.5[theta]. Its specific gravity was .464; and the volume of air was about seven times that of the gas used (or one-eighth of the mixture), and was only 111/2 per cent. by weight more than was needed for perfect combustion. The results arrived at were ...

... sand into his pan, which was a broad, shallow dish of sheet iron. Then water was dipped into the pan until it was full, when he whirled it swiftly about and up and down. This allowed the gold, on account of its greater specific gravity, to fall to the bottom, while the sand itself was floated off by the agitation. Tim had learned the knack of dipping the pan sideways, so as gradually to get rid of the worthless stuff, while the heavy yellow particles ...

... essential forces with which to put each other in motion, and thus are themselves a source of life. Matter immediately begins to strive to fashion itself. The scattered elements of a denser kind, by means of their attraction, gather from a sphere around them all the matter of less specific gravity; again, these elements themselves, together with the material which they have united with them, collect in those points where the particles of a still denser kind are found; these in like manner join still denser particles, and so on. If we follow in ...

... of facts obtained by experiment and observation, aided by mathematical discussion. It enforced the principle that the true method of studying Nature is by experimental interrogation. The researches of Archimedes in specific gravity, and the works of Ptolemy on optics, resemble our present investigations in experimental philosophy, and stand in striking contrast with the speculative vagaries of the older writers. Laplace says that the only observation ...

... rapid growth after a victory. That is the temporary vanity of torrents swelled by a storm. Civilized people, especially in our day, are neither elevated nor abased by the good or bad fortune of a captain. Their specific gravity in the human species results from something more than a combat. Their honor, thank God! their dignity, their intelligence, their genius, are not numbers which those gamblers, heroes and conquerors, can put in the lottery of battles. Often a battle is lost and progress is conquered. There is less ...

Zadig, finding he had raised his curiosity, increased it still further by acquainting him with many things that related to commerce, the specific gravity of metals, and commodities under an equal bulk; the properties of several useful animals; and the means of rendering those useful that are not naturally so. At last Setoc began to consider Zadig as a sage, and preferred him to his companion, whom he had formerly ...

... transparent than paper of the same thickness. A thin transverse section placed under the microscope exhibits a series of curvilinear lines diverging from the centre and interlacing each other with great regularity and beauty, closely resembling in appearance the engine-turning of a watch. It possesses a specific gravity varying from 1.888 in the tooth of the walrus, to 2.843 in that of the elephant. Its mean gravity is therefore about two and a half times greater than water. The best, finest, and most valuable ivory is that obtained from the African elephant. When recently cut, it exhibits something ...

... conditions, the law, namely, that anything will float which bulk for bulk is lighter than the volume of water displaced by it, so that by including in our calculations the displacement of the vessel as well as the specific gravity of the material, we now make iron float by the very same law by which it sinks. This example shows that the function of the Personal Factor is to analyze the manifestations of Law which are spontaneously afforded by Nature and to discover the Universal Affirmative Principle which lies hidden ...

... if any reliance can be placed on the concurrent traditions of all religions, Pagan as well as Christian, supported by wide-spread popular belief, the high mental exaltation induced by religious abstraction, and also by other vehement affections of the mind, is actually attended with a diminished specific gravity. Of alleged ecclesiastical miracles of this kind it is better to say nothing. The Roman Catholic and the Hindoo devotees equally claim for their adepts in religious contemplation an exemption from (among other earthly liabilities) the hindrance of weight. In the rapture of prayer, ...

In fact one should always make sure of a stone by seeing that two or three different tests point to the ...
