עמוד 121 - And Abraham hearkened unto Ephron; and Abraham weighed to Ephron the silver, which he had named in the audience of the sons of Heth, four hundred shekels of silver, current money with the merchant.
עמוד 293 - If a beam of daylight be admitted into a dark room by a crevice -fa of an inch broad, and received by the eye at the distance of 10 to 12 feet through a prism of flint glass, free from veins, held near the eye, the beam is seen to be separated into the four following colours only, red, yellowish green, blue, and violet, in the proportions represented in fig.
עמוד 236 - Under these circumstances a vivid action was soon observed to take place. The potash began to fuse at both its points of electrization. There was a violent effervescence at...
עמוד 236 - ... small globules having a high metallic lustre, and being precisely similar in visible characters to quicksilver, appeared, some of which burnt with explosion and bright flame, as soon as they were formed, and others remained, and were merely tarnished, and finally covered by a white film which formed on their surfaces.
עמוד 134 - Hitherto we have explained the phenomena of the heavens and of our sea by the power of gravity, but have not yet assigned the cause of this power.

Colours are not qualifications of light, derived from refractions, or reflections of natural bodies (as 'tis generally believed) but original and connate properties, which in divers rays are divers.
עמוד 228 - ... periodic law could not have been discovered, and which rendered its appearance natural and intelligible. In the first place, it was at that time that the numerical value of atomic weights became definitely known. Ten years earlier such knowledge did not exist, as may be gathered from the fact that in 1860 chemists from all parts of the world met at Karlsruhe in order to come to some agreement, if not with respect to views relating to atoms, at any rate as regards their definite representation....
עמוד 134 - But hitherto I have not been able to discover the cause of those properties of gravity from phenomena, and I frame no hypotheses. For whatever is not deduced from the phenomena is to be called an hypothesis, and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy.
עמוד 171 - Pleiads, rising thro" the mellow shade, Glitter like a swarm of fire-flies tangled in a silver braid. Here about the beach I wander'd, nourishing a youth sublime With the fairy tales of science, and the long result of Time...
עמוד 234 - A second edition followed the next year, and the memoir was also published in the Annales de Chimie in 1806. Sir Humphry says : It Is very natural to suppose that the repellent and attractive energies are communicated from one particle to another particle of the same kind, so as to establish a conducting chain in the fluid ; and that this is really the case seems to be shown by many facts...
