Page i - Mrs. Marcet's Conversations on Chemistry, in which the Elements of that Science are familiarly explained and illustrated by Experiments.
Page 342 - The phenomenon was independent of the presence of air ; I found that it took place when the alkali was in the vacuum of an exhausted receiver. The substance was likewise produced from potash fused by means of a lamp, in glass tubes confined by mercury, and furnished with hermetically inserted platina wires, by which the electrical action was transmitted. But this operation could not be carried on for any considerable time ; the glass was rapidly dissolved by the action of the alkali, and this substance...
Page 375 - ... there is no evidence which ought to induce us to suppose that it loses a portion of oxygen ; and the effect appears to be owing merely to the separation of the gelatine, from the small quantity of albumen with which it was combined in the organized form, by the solvent powers of water.
Page 363 - Thus we may use oxyde of iron dissolved in sulphuric acid, in order to dye wool ; but for cotton and linen, it is better to dissolve it in acetous acid. Were it possible to procure a sufficient number of colouring matters, having a strong affinity for cloth, to answer...
Page 26 - ... of it. Emily. And yet this book is not so cold as the table on which it lies, though both are at an equal distance from the fire. and actually in contact with each other, so that, according to your theory, they should be exactly of the same temperature.
Page 341 - There waa a violent effervescence at the upper surface ; at the lower, or negative surface, there was no liberation of elastic fluid, but small globules having a high metallic lustre, and being precisely similar in visible characters to quicksilver, appeared, some of which burnt...
Page iii - IK venturing to offer to the public, and more particularly to the female sex, an introduction to Chemistry, the author, herself a woman, conceives that some explanation may be required ; and she feels it the more necessary to apologize for the present undertaking, as her knowledge of the subject is but recent, and as she can have no real claims to the title of chemist.
Page 363 - Were it possible to procure a sufficient number of colouring matters, having a strong affinity for cloth, to answer all the purposes of dyeing, that art would be exceedingly simple and easy. But this is by no means the case ; if we except indigo, the dyer is scarcely possessed of a dye stuff which yields of itself a good colour, sufficiently permanent to deserve the name of a dye. This difficulty, which at first sight appears insurmountable, has been obviated by a very ingenious contrivance. Some...
Page 51 - Mrs. B. It may be done by cooling the several bodies to the same degree, in an apparatus adapted to receive and measure the caloric which they give out. Thus, if you plunge them into three equal quantities of water, each at the same temperature, you will be able to judge of the relative quantity of caloric which the three bodies contained, by that, which, in cooling...
