Page 67 - And the LORD was with Judah ; and he drave out the inhabitants of the mountain ; but could not drive out the inhabitants of the valley, because they had chariots of iron.
Page 156 - But if we conceive a being whose faculties are so sharpened that he can follow every molecule in its course, such a being, whose attributes are still as essentially finite as our own, would be able to do what is at present impossible to us.
Page 156 - Now let us suppose that such a vessel is divided into two portions, A and B. by a division in which there is a small hole, and that a being, who can see the individual molecules, opens and closes this hole, so as to allow only the swifter molecules to pass from A to B, and only the slower ones to pass from B to A. He will thus, without expenditure of work, raise the temperature of B and lower that of A, in contradiction to the second law of thermodynamics.
Page 196 - The person may be accepted on the whole as a fair representative of the germ, and being so, the statistical laws which apply to the persons would apply to the germs also, though with less precision in individual cases. Now this law is strictly consonant with the observed binary subdivisions of the germ cells, and the concomitant extrusion and loss of one-half of the several contributions from each of the two parents to the germ-cell of the offspring.
Page 286 - the study of agencies under social control that may improve or impair the racial qualities of future generations, either physically or mentally.
Page 71 - The mother of Sisera looked out at a window and cried through the lattice Why is his chariot so long in coming? why tarry the wheels of his chariots?
Page 42 - Life is a vale, its paths are dark and rough Only because we do not know enough : When Science has discovered something more We shall be happier than we were before.
Page 200 - On the Bearing of Mendelian Principles of Heredity on current Theories of the Origin of Species.
Page 159 - Operating among such phenomena the gross statistical method is a misleading instrument ; and, applied to these intricate discriminations, the imposing Correlation Table into which the biometrical Procrustes fits his arrays of unanalysed data is still no substitute for the common sieve of a trained judgment. For nothing but minute analysis of the facts by an observer thoroughly conversant with the particular plant or animal, its habits and properties, checked by the test of crucial experiment, can...
Page 155 - One of the best established facts in thermodynamics is that it is impossible in a system enclosed in an envelope which permits neither change of volume nor passage of heat, and in which both the temperature and the pressure are everywhere the same, to produce any inequality of temperature or of pressure without the expenditure of work.
