Strana 25 - Nevertheless, it is necessary to remember that there is a wider Teleology which is not touched by the doctrine of Evolution, but is actually based upon the fundamental proposition of Evolution. That proposition is, that the whole world, living and not living, is the result of the mutual interaction according to definite laws of the forces possessed by the molecules, of which the primitive nebulosity of the universe was composed.
Strana 25 - If one plant or animal differs from another, or the parent from the child, it is because in the building-up process the determinations of molecular motion were different in the two cases ; and the true and fundamental ground of the difference must be sought for in the cause of the determination of molecular motion.
Strana 70 - ... be turned, we have the colours shown in the regular order. If the plates A and B have their axes directed at 45° on the same side of the axis of C, and the pieces be turned round bodily as before the colours change in the same order as above, and go through their cycle once in every...
Strana 71 - And it is further to be noticed, as the formula given above indicates, that the centres of the rings will be bright or dark according as the analyzer stands at 0° or 90°.
Strana 305 - ... point of rest made by each molecule of the air, determines the pitch or note ; so, in the theory of light, the frequency of the pulses, or number of impulses made on our nerves in a given time by the ethereal molecules next in contact with them, determines the...
Strana 422 - That so far from chemical influences being restricted to the more refrangible rays, every part of the spectrum, visible and invisible, can give rise to chemical changes, or modify the molecular arrangement of bodies...
Strana 321 - ... a method of detecting the phases of vibration in the air surrounding a sounding body ; and thereby measuring directly in the vibrating air the length of its waves and exploring the form of its wave-surface...
Strana 71 - ... of rotation ; and if the analyser be turned in the same direction, the colours change, but in the reverse order. The explanation of this is to be found in the fact that when the plates A and...
Strana 236 - ... of water. Air was slowly driven through the apparatus, and, having been strongly ozonized by the action of the electricity, bubbled up through the water. This was continued for an hour and a half. At the end of this time common air was passed through the apparatus to displace the ozone left in it, the tubes were removed, and the bottle closed with a glass stopper. On opening the bottle some time afterward, there was an unmistakable odor of sulphurous oxide, and the water reddened blue litmus...
