Invention and Discovery: Curious Facts and Characteristic Sketches. AnonymousЧитать онлайн книгу.
NOTE.
In the annals of Invention and Discovery, it may be said without undue boasting, no nation of modern times can lay claim to such an eminent position as Great Britain; and her many ingenious and intrepid adventurers into what they found unknown regions of the arts, the sciences, and the earth's surface, have so largely contributed to raise her to her great place and power, that it is mere justice and self-interest to bestow on them grateful rewards in life, and renown after death. In this little volume are brought together a number of sketches and memoranda, illustrating the history of discovery, and the lives and labours of inventors and explorers, not of our own country alone, but of others—for knowledge is of no country, but of all. The object of the collector has been rather to present the popular than the strictly scientific side of his subject—to furnish materials of interest and amusement, as well as instruction; and if now and then he has been tempted to stray into bye-paths of anecdote and gossip, excuse may readily be found in the fact that the private life of our men of science, often singularly noble and full of character, is apt to be altogether obscured by the brilliancy of the results of their secret and silent toil. This volume will have served its purpose, if it excites an appetite for fuller and deeper inquisition into the sources of British greatness and of modern civilisation.

POETIC PROPHECIES.
In Dr. Darwin's Botanic Garden, first published in 1789, but written, it is well known, at least twenty years before the date of its publication, occurs the following prediction respecting Steam:—
"Soon shall thy arm, unconquer'd Steam, afar
Drag the slow barge, or drive the rapid car;
Or, on wide-waving wings expanded bear
The flying chariot through the fields of air,[1]
Fair crews triumphant leaning from above,
Shall wave their fluttering 'kerchiefs as they move;
Or warrior bands alarm the gaping crowd,
And armies shrink beneath the shadowy cloud:
So mighty Hercules o'er many a clime
Waved his huge mace in virtue's cause sublime;
Unmeasured strength with early art combined,
Awed, served, protected, and amazed mankind."
A distinguished photographer imagines that he has traced the foreshadowing of his delightful science in the following passage from our great epic poet:
"With one touch virtuous
Th' arch-chemic sun, so far from us remote,
Produces."
Paradise Lost, b. iii. v. 608.
| [1] | Darwin projected an "aërial steam-carriage," in which he proposed to use wings similar to those of a bird, to which motion was to be given by a gigantic power worked by high-pressure steam, though the details of his plan were not bodied forth. |
CONSTRUCTION OF THE THAMES TUNNEL.
When the ingenious Miss Pardoe visited Constantinople in 1836, she was not less surprised than gratified by the inquiry of an Albanian chief, as to the probable completion of the Thames tunnel. This, however, is but one of the many instances of the anxiety with which the great work was watched throughout continental Europe. In Egypt, too, where a new country is rising, phœnix-like, upon the ashes of the old world, the progress of the tunnel was regarded with like curiosity; participated, indeed, throughout the civilised world. This interest is fully attested by the visitors' book at the Tunnel, wherein are inscribed the names of scientific men belonging to nearly every city of importance. The engineer of this great work, Mr. (afterwards Sir) Mark Isambard Brunel, completed his design in 1823; and amongst those who then regarded it as practicable were the Duke of Wellington and the late Dr. Wollaston. The works were commenced in 1825, and the Tunnel itself in 1826; and by March, 1827, it had advanced about one-third of the whole length. All proceeded well till May 18, when the river burst into the Tunnel with such velocity and volume, as to fill it in fifteen minutes; but, although the men were at work, no lives were lost. The hole, thirty-eight feet deep, was closed with bags of clay and hazel-rods, the water pumped out, and the works resumed in September. On Jan. 12, 1828, the river broke in a second time, and filled the Tunnel in less than ten minutes; when the rush of water brought with it a strong current of air that put out the lights; six of the workmen were lost. For some distance, Mr. Brunel, junior, struggled in total darkness, and the rush of the water carried him up the shaft. The Tunnel was again cleared, and the part completed found to be sound. Hundreds of plans were proposed for its completion; the funds of the company were too low to proceed, and above 5000l. was raised by public subscription.
For seven years the work was suspended; but, by advances from Government, it was resumed in 1835. On April 23, 1837, there was a third irruption of the river; a fourth on Nov. 2, 1837, with the loss of one life; and, on March 6, 1838, the fifth and last irruption took place. Thus, of the tunnel there were completed—
