Seite 174 - In the use of this form of grating, the slit is placed in the circumference of a circle whose diameter is equal to the radius of curvature of the grating, and which touches its surface.
Seite 437 - These facts will be referred to when we come to consider the question of warm polar climates. It would be impossible within the limits of the present paper to give even the briefest outline of the recent discoveries in regard to interglacial periods. But though this were possible it would be wholly unnecessary, as the facts which have already been adduced by Mr. Wallace himself are perfectly sufficient for our present purpose. If now it be true, as it undoubtedly is, that the Hessle...
Seite 353 - I drew the conclusion, that the combinations and decompositions by electricity were referable to the law of electrical attractions and repulsions, and advanced the hypothesis, " that chemical and electrical attraction were produced by the same cause, acting in one case on particles, in the other on masses ;" and that the same property, under different modifications, was the cause of all the phenomena exhibited by different voltaic combinations.
Seite 289 - ... especially if not learned young, are likely to remain unlearned. I will not further insist upon the educational importance of mathematics and science, because with respect to them I shall probably be supposed to be prejudiced. But of modern languages I am ignorant enough to give value to my advocacy. I believe that French and German, if properly taught, which I admit they rarely are at present, would go far to replace Latin and Greek from a disciplinary point of view, while the actual value of...

Seite 289 - From the general spread of a more scientific education, we are warranted in expecting important results. Just as there are some brilliant literary men with an inability, or at least a distaste practically amounting to inability, for scientific ideas, so there are a few with scientific tastes whose imaginations are never touched by merely literary studies. To save these from intellectual stagnation during several important years of their lives is something gained, but the thorough-going advocates...
Seite 295 - Annals of the New York Lyceum of Natural History
Seite 298 - Cotton, the Fulminates, Picrates, and Chlorates; also, the Chemistry and Analysis of the Elementary Bodies which enter into the Manufacture of the principal Nitro-Compounds.
Seite 289 - ... the question upon the supposition that the majority of boys attain either to a knowledge of the languages or to an appreciation of the writings of the ancient authors. The contrary is notoriously the truth; and the defenders of the existing system usually take their stand upon the excellence of its discipline. From this point of view there is something to be said. The laziest boy must exert himself a little in puzzling out a sentence with grammar and dictionary, while instruction and supervision...
Seite 375 - Archimedes possessed so high a spirit, so profound a soul, and such treasures of scientific knowledge, that though these inventions had now obtained him the renown of more than human sagacity, he yet would not deign to leave behind him any commentary or writing on such subjects ; but, repudiating as sordid and ignoble the whole trade of engineering, and every sort of art that lends itself to mere use and profit, he placed his whole affection and ambition in those purer speculations where there can...
