Strona 241 - And these things being considered, it seems probable to me, that God in the beginning formed matter in solid, massy, hard, impenetrable, moveable particles, of such sizes and figures, and with such other properties, and in such proportion to space, as most conduced to the end for which he formed them...
Strona 150 - In short, he must become impressed with the salutary truth, that no one can be perfectly free till all are free ; no one can be perfectly moral till all are moral ; no one can be perfectly happy till, all are happy.
Strona 292 - FARADAY AS A DISCOVERER. One vol., I2mo. Cloth, $1.00. " It has been thought desirable to give you and the world some image of Michael Faraday as a scientific investigator and discoverer.
Strona 141 - A fire-mist and a planet, A crystal and a cell, A jelly-fish and a saurian. And caves where the cave-men dwell: Then a sense of law and beauty. And a face turned from the clod, Some call it Evolution, And others call it God.
Strona 241 - ... these primitive particles, being solids, are incomparably harder than any porous bodies compounded of them; even so very hard as never to wear or break in pieces; no ordinary power being able to divide what God himself made one in the first creation.
Strona 12 - An act relating to labor, constituting chapter thirty-one of the consolidated laws," is amended by the addition of a new section numbered fifty-eight, to read as follows: § 58.

Strona 197 - It stands complete and apparently well tested, but without any visible means of support. These supports must obviously exist, and the most fascinating problem of modern physics is to find them. Experiment has outrun theory, or, better, guided by erroneous theory, it has discovered relationships which seem to be of the greatest interest and importance, but the reasons for them are as yet not at all understood.
Strona 154 - ... and at a velocity which can be calculated from the rate of extension of the spring. In this way all the data required for the determination of the absolute kinematic viscosity of the fluid were determined.
Strona 292 - I may be with the researches and discoveries of that great master, however numerous the illustrations which occur to me of the loftiness of Faraday's character and the beauty of his life — still to grasp him and his researches as a whole; to seize upon the ideas which guided him, and connected them; to gain entrance into that strong and active brain, and read from it the riddle of the world...
