Strona 217 - Bulletin de l'Association des Chimistes de Sucrerie et de Distillerie de France et des Colonies, the leading French sugar periodical.
Strona 25 - I undertook the experiment of electrizing pure liquid fluoric acid with considerable interest, as it seemed to offer the most probable method of ascertaining its real nature ; but considerable difficulties occurred in executing the process. The liquid fluoric acid immediately destroys glass, and all animal and vegetable substances; it acts on all bodies containing metallic oxides; and I know of no substances which are not rapidly dissolved or decomposed by it, except metals, charcoal, phosphorus,...
Strona 26 - From the general tenour of the results that I have stated, it appears reasonable to conclude that there exists in the fluoric compounds a peculiar substance, possessed of strong attractions for metallic bodies and hydrogen, and which combined with certain inflammable bodies forms peculiar acids, and which, in consequence of its strong affinities and high decomposing agencies, it will be very difficult to examine in a pure form, and, for the sake of avoiding circumlocution, it may be denominated fluorine,...
Strona 80 - The old order changeth, yielding place to new, And God fulfils Himself in many ways, Lest one good custom should corrupt the world.
Strona 195 - I invite you to make a flight with me in an airship, as it were, over the fields where the chemical industry holds sway, and, from our point of vantage, to take a bird's-eye view of the latest achievements of this industry. Now and then we shall make a landing and examine the most attractive features a little more closely. PRODUCTION OF POWER. The question of power, which is of the utmost importance in every industry, and especially in the great synthetic processes by means of which nitric acid and...
Strona 256 - ... synthetic rubber will bring the millions which prophets see in its. exploitation, I must reply that I do not know. Surely not in the immediate future, although synthetic rubber will certainly appear on the market in a very short time. But I hope to live long enough to see art triumph also here over nature. We are now at the end of our journey. We have flown not only over the field of Germany, but also over all other countries where the chemical industry is cultivated. We have taken a passing...
Strona 228 - Ancient microscopes and optical instruments gathered from all quarters of Europe will form another important feature, and a selection of surgical instruments used by famous surgeons when operating on historical personages is promised. The collection of amulets and charms connected with English folk medicine will be very complete, and will constitute an exhibit of more than ordinary interest. A fine collection of early medical medals and coins from the Graeco-Roman period, ancient manuscripts and...
Strona 97 - Radio-elements, p. 30) I stated the rule that held good in several cases, that when the a-particle was expelled the atom passed from a family of even number in the Periodic Table to the next lower-numbered even family, the family of odd number being always missed. Further, in the changes in which the a-particle was not expelled the atom in several cases reverted to its original group, resulting in a curious alternation of properties as the series proceeds. Now, when this occurs, an element of the...
Strona 256 - ... your judgment whether this is true or not, like much that printer's ink patiently transfers to paper. I am right in the midst of this excitement. I have employed articles made of synthetic rubber, and for some time I have used automobile tires made of this material. Yet, if you ask me to answer you honestly and truly when synthetic rubber will bring the millions which prophets see in its exploitation, I must reply that I do not know. Surely not in the immediate future, although synthetic rubber...
Strona 264 - Equivalents.— The Mortar and its Technical Equivalents. — Measuring Instruments and their Technical Equivalents.— Materials Used in Chemical Engineering and their Mode of Application.— Technical Research and the Designing of Plant.— Conclusion.— Chemicals and Materials. — INDEX. " Excellent. . . . Every student of chemistry attending a technical course should obtain a copy.
