Page 296 - Of absolute rest Nature gives us no evidence : all matter, as far as we can ascertain, is ever in movement, not merely in masses, as with the planetary spheres, but also molecularly, or throughout its most intimate structure : thus every alteration of temperature produces a molecular change throughout the whole substance heated or cooled ; slow chemical or electrical actions, actions of light or invisible radiant forces, are always at play, so that as a fact we cannot predicate of any portion of...

Page 155 - Ehrenberg's genus and ought to bear the name ampelicida. It makes its appearance only on nearly full grown berries, exhibiting in the first stage a discolored spot on the side, but never at the base of the berry, about two lines in diameter, with a dark spot in the centre. This spot soon becomes light brown and remains so, while the surrounding part of the berry gets darker and exhibits a rough or (under the magnifier) pustulous surface ; gradually, now, the berry shrivels up and turns black.

Page 14 - ... remarkable fact which has been established, that the magnetic force is greater in both the northern and southern hemispheres in the months of December, January, and February, when the sun is nearest to the earth, than in those of May, June, and July, when he is most distant from it : whereas if the effect were due to temperature, the two hemispheres should be oppositely instead of similarly affected in each of the two periods referred to.
Page 491 - No other satisfactory method of exploration, except along the course of the river, could be adopted to determine its actual course, and peculiar natural features, and James White, as the pioneer of this enterprise, will probably retain the honor of being the only man who has traversed, through its whole course, the Great Canon of the Colorado, and lived to recount his observations on this perilous voyage.
