Although the shores of the Bay of Naples have remained in general with unchanged elevation for about two thousand years, they have here and there been subjected to slight oscillations which are most likely connected with the movement of volcanic matter toward the vents where it is to find escape.
This problem is practically solved now, and in the near future every station, every ship, and each installation will have its own key, and will respond to none other than the particular vibrations, wave lengths, or oscillations, for which it is adjusted.
The principal anomalies observed by Captain Duperrey were at the Isle of France, Mons, Guam, and the Island of Ascension. At Ascension, the acceleration, as noticed by Captain Sabine, was five or six oscillations, even supposing the depression to be 1.228. At other stations the difference was almost nothing; and in some, the motion of the pendulum was retarded.
Yet, the fact that these extremes of temperature are associated in some way with the change of the sun's place in the heavens must, in time, have impressed itself upon even a rudimentary intelligence. It is hardly necessary to add that this is not meant to imply any definite knowledge of the real meaning of, the seeming oscillations of the sun.
As distinguished from this system, however, modern wireless telegraphy so called has its basis in the utilization of electric or ether waves in free space, such waves being set up by electric oscillations, or surgings, of comparatively high potential and high frequency, produced by the operation of suitable electrical apparatus.
Another volcano of the West India Islands, that of St. Vincent, affords an example of these extraordinary connections. This volcano had not emitted flames since 1718, when they burst forth anew in 1812. The total ruin of the city of Caracas preceded this explosion thirty-five days, and violent oscillations of the ground were felt both in the islands and on the coasts of Terra Firma.
The fandango turns and oscillates, to the tune of an ancient waltz. All the arms, extended and raised, agitate themselves in the air, rise or fall with pretty, cadenced motions following the oscillations of bodies. The rope soled sandals make this dance silent and infinitely light; one hears only the frou-frou of gowns, and ever the snap of fingers imitating the noise of castanets.
The third instrument is the seismograph, which is so arranged that it will accurately record the number, succession, direction, amplitude and period of successive oscillations. This last instrument is by far the most delicate of the three.
They were destitute, but they were no longer overshadowed by the fear of disgrace, the misery of subterfuge, the bewildering oscillations between pity for the man who could not have what he wanted and shame for his ceaseless striving after pleasure, his shifts to get it, his reproaches and complaints.
The temperature of deep waters seems to be constant for all latitudes at 39°; so that an immense area of the North Atlantic must have had its conditions unaffected by tertiary or post-tertiary oscillations." Wyville Thomson adopted from eminent physical writers; but the general justice of the reasoning is not affected by this circumstance, and Dr.
