Many of our readers may remember a suggestion by Sir William Thomson, now Lord Kelvin, made twenty or thirty years ago, that life may have been brought to our planet by the falling of a meteor from space. This does not, however, solve the difficulty indeed, it would only make it greater.
The Trongate is a noble street; the park on the banks of the Kelvin, laid out by Sir Joseph Paxton, furnishes some pleasant walks; the Sauchyhall-road is an agreeable promenade; Claremont, Crescent and Park Gardens consist of houses which would be of the first class even in Belgravia or Tyburnia; and from the West-end streets, there are prospects of valley and mountain which are worth going some distance to see.
Now he had that complete lack of satisfaction in his own performance which superficial people think to be modesty, though it springs instead from the sword-stiff extreme of pride; when he made his century in a school match he was galled by the knowledge that he was not as good a player as Ranji, and when he was head of the science side his pleasure was mitigated to nearly nothing by his sense that still he did not know as much about these things as Lord Kelvin.
The address was quite inadequate and the unfortunate visitor had a rather cool reception. Freeman was only one of many in all this. The astronomer R.A. Proctor came to similar grief for a similar gaucherie, and even so famous a man as Lord Kelvin suffered in like manner.
But it must be granted that it was strangely narrow. The University was not to be despised which could turn out for successive senior wranglers from 1840 to 1843 such men as Leslie Ellis, Sir George Stokes, Professor Cayley, and Adams, the discoverer of Neptune, while the present Lord Kelvin was second wrangler and first Smith's prizeman in 1845.
Such estimates, for example, as that of Lord Kelvin as to the probable heat-giving life of the sun must now be multiplied from fifty to five hundred times. In like manner the length of time that the earth has been sufficiently cool to support animal and vegetable life must be re-estimated.
Some of them said the telephone was impossible, while others said that "nothing could be simpler." Almost all were agreed that what Bell had done was a humorous trifle. But Lord Kelvin persisted. He hammered the truth home that the telephone was "one of the most interesting inventions that has ever been made in the history of science."
While these preparations were going on Lord Kelvin and the other men of science entered with the utmost eagerness upon those studies, the prosecution of which had been the principal inducement leading them to embark on the expedition. But, almost all of the face of the planet being covered with the flood, there was comparatively little that they could do.
The electrical storage battery, compressed air, and other agencies which will be referred to later on, have now supplied this want of the windmill builder, but in the meantime his trade has been to a large extent destroyed. For its revival there is no doubt that, as Lord Kelvin remarked in the address already quoted, "the little thing wanted to let the thing be done is cheap windmills."
They preceded the epoch when, thanks to numerous physicists, among whom Lord Kelvin undoubtedly occupies a preponderating position, we succeeded in sinking the first cable; but they were not abandoned, even after that date, for they gave hopes of a much more economical solution of the problem.
