Popular passages
Page 237 - water is composed of two volumes of hydrogen to one of oxygen — and if we should now mix these gases together and set fire to them by an electrical spark, both gases would entirely disappear, and a small quantity of water would be formed.
Page 20 - Chemical Attraction, or the Attraction of Composition, consists in the peculiar tendency which bodies of a different nature have to unite with each other. It is by this force that all compositions and decompositions are effected. EMILY. What is the difference between chemical attraction, and the attraction of cohesion or of aggregation, which you
Page 5 - highly useful; and in those arts which relate to the comforts and conveniences of life, it would be endless to enumerate the advantages which result from the study of this science. CAROLINE. But pray tell us more precisely in what manner the discoveries of chemists have proved so beneficial to society.
Page 28 - for, in separating the different coloured rays of light by a prism (as we did some time ago), he found that the greatest heat was beyond the spectrum, at a little distance from the red rays, which, you may recollect, are the least refrangible. EMILY. I should like to try that experiment.
Page 278 - and that of phosphorus, a phosphoret of lime. This latter compound, I was going to say, has the singular property of decomposing water, merely by being thrown into it. It effects this by absorbing the oxygen of water, in consequence of which bubbles of hydrogen gas ascend, holding in solution a small quantity of phosphorus.
Page 33 - MRS. B. And likewise of things which do not burn, as, for instance, the warmth of the body; in a word, all heat that is sensible, whatever may be its degree, or the source whence it is derived. CAROLINE. What then are the other modifications of caloric? It must be a strange kind of heat
Page 179 - organs of the frog, but upon the electrical agency, of the metals, which is excited by the moisture of the animal; the organs of the frog being only a delicate test of the presence of electric influence. He proved, by a variety of experiments, that when two metals, having been placed in contact, are afterwards separated, the equilibrium
Page 58 - MRS. B. This experiment is exactly similar to that made with the heated bullet: for, if we consider the thermometer as the hot body (which it certainly is in comparison to the ice), you may then easily understand that it is by the loss of the caloric which the thermometer sends to the
Page 26 - that three or four cannot combine together without any of them being precipitated? MRS. B. That is sometimes the case; but, in general, the stronger affinity destroys the weaker; and it seldom happens that the attraction of several substances for each other is so equally balanced as to produce such complicated compounds. CAROLINE.
Page ix - by the wonders of Nature, studied in this new point of view, were still fresh and strong, she might, perhaps, succeed the better in communicating to others the sentiments she herself experienced. acquired some slight, knowledge of natural philosophy, a circumstance so desirable, that the Author has, since the original publication of this
