How does it come about that alongside of the idea of ponderable matter, which is derived by abstraction from everyday life, the physicists set the idea of the existence of another kind of matter, the ether? The explanation is probably to be sought in those phenomena which have given rise to the theory of action at a distance, and in the properties of light which have led to the undulatory theory.
I began to listen with a determination to remember it in order, but it was without method, or order, or system. It was like a beam of light moving in the undulatory waves, meeting with occasional meteors in its path; it was exceedingly captivating. It surprised me that there was not only no commonplace thought, but there was no commonplace expression.
Thus, though the undulatory theory was held back for a time, it gathered strength in the interval, and its development within the last half century has been so rapid and triumphant as to leave no rival in the field. We have now to turn to the investigation of new classes of phenomena, of which it alone can render a satisfactory account.
It is the flavor that gives to speech its undulatory quality, and redeems it from desert sameness. It pervades the motives and gives direction as well as a pleasing fertility to all behavior. It is pervasive without becoming obtrusive. It steals into the senses as quietly as the dawn and causes life to smile.
And when she walks, she minds me of my grandsire's leopardess, which once did stride from shadow to shadow in the palace with that undulatory, unearthly grace. In nature, she is world-compelling. When first she met me, she took my face between her palms and gazed into mine eyes. Ai! she bewitched me, then and there.
But even as they gazed the cloud seemed to sink like a fairy mirage to the earth again, the whole train disappeared, and only the empty stretching track returned. They did not know that this seemingly flat and level plain was really undulatory, and that the vanished train had simply dipped below their view on some further slope even as it had once before.
These are referred by the undulatory theory to the interference of waves which have passed directly through the film, with others which have suffered two reflections within the film, and are thus completely accounted for. The Diffraction of Light. Newton's espousal of the Emission Theory is said to have retarded scientific discovery.
Purely as a consequence of the chemico-physical nature of the germ, of the properties of the substances included in it on the one hand, and of the implicit structure and configuration of its parts, down to the intrinsic specific undulatory rhythm of its molecules, it must follow that its mass grows exactly as it does, and not otherwise, that it behaves as it does and not otherwise, duplicating itself by division after division, and by intricate changes arranging and rearranging the results of division until the embryo or larva, and finally the complete organism, is formed.
This instrument was called the 'electromotograph, and it occurred to Edison that in a similar way the undulatory currents from his carbon transmitter might, by varying the friction between a metal stylus and the prepared surface, put a tympanum in vibration, and reproduce the original sounds.
Although it caused no damage, its undulatory motion was sufficiently strong to affect certain persons with a sensation akin to sea-sickness. It was followed by rain in torrents, on the 20th, 21st, and 22nd. On the latter day especially, we were, for half an hour, surrounded with water to a considerable depth. We could not see three yards before us.
