fear of the credulous; a long time elapsed before it became employed
as a useful motive…power。 The inquiries and experiments on the
subject extended through many ages。 Friar Bacon; who flourished in
the thirteenth century; seems fully to have anticipated; in the
following remarkable passage; nearly all that steam could accomplish;
as well as the hydraulic engine and the diving…bell; though the
flying machine yet remains to be invented:
〃I will now;〃 says the Friar; 〃mention some of the wonderful works of
art and nature in which there is nothing of magic; and which magic
could not perform。 Instruments may be made by which the largest
ships; with only one man guiding them; will be carried with greater
velocity than if they were full of sailors。 Chariots may be
constructed that will move with incredible rapidity; without the help
of animals。 Instruments of flying may be formed; in which a man;
sitting at his ease and meditating on any subject; may beat the air
with his artificial wings; after the manner of birds。 A small
instrument may be made to raise or depress the greatest weights。 An
instrument may be fabricated by which one man may draw a thousand men
to him by force and against their will; as also machines which will
enable men to walk at the bottom of seas or rivers without danger。〃
It is possible that Friar Bacon derived his knowledge of the powers
which he thus described from the traditions handed down of former
inventions which had been neglected and allowed to fall into
oblivion; for before the invention of printing; which enabled the
results of investigation and experience to be treasured up in books;
there was great risk of the inventions of one age being lost to the
succeeding generations。 Yet Disraeli the elder is of opinion that the
Romans had invented printing without being aware of it; or perhaps
the senate dreaded the inconveniences attending its use; and did not
care to deprive a large body of scribes of their employment。 They
even used stereotypes; or immovable printing…types; to stamp
impressions on their pottery; specimens of which still exist。 In
China the art of printing is of great antiquity。 Lithography was well
known in Germany; by the very name which it still bears; nearly three
hundred years before Senefelder reinvented it; and specimens of the
ancient art are yet to be seen in the Royal Museum at Munich。*

Steam…locomotion by sea and land; had long been dreamt of and
attempted。 Blasco de Garay made his experiment in the harbour of
Barcelona as early as 1543; Denis Papin made a similar attempt at
Cassel in 1707; but it was not until Watt had solved the problem of
the steam…engine that the idea of the steam…boat could be developed
in practice; which was done by Miller of Dalswinton in 1788。 Sages
and poets have frequently foreshadowed inventions of great social
moment。 Thus Dr。 Darwin's anticipation of the locomotive; in his
Botanic Garden; published in 1791; before any locomotive had been
invented; might almost be regarded as prophetic:
Soon shall thy arm; unconquered Steam! afar
Drag the slow barge; and drive the rapid car。
Denis Papin first threw out the idea of atmospheric locomotion; and
Gauthey; another Frenchman; in 1782 projected a method of conveying
parcels and merchandise by subterraneous tubes;*

after the method recently patented and brought into operation by the
London Pneumatic Despatch Company。 The balloon was an ancient Italian
invention; revived by Mongolfier long after the original had been
forgotten。 Even the reaping machine is an old invention revived。 Thus
Barnabe Googe; the translator of a book from the German entitled 'The
whole Arte and Trade of Husbandrie;' published in 1577; in the reign
of Elizabeth; speaks of the reaping…machine as a worn…out
inventiona thing 〃which was woont to be used in France。 The device
was a lowe kinde of carre with a couple of wheeles; and the frunt
armed with sharpe syckles; whiche; forced by the beaste through the
corne; did cut down al before it。 This tricke;〃 says Googe; 〃might be
used in levell and champion countreys; but with us it wolde make but
ill…favoured woorke。〃*

The Thames Tunnel was thought an entirely new manifestation of
engineering genius; but the tunnel under the Euphrates at ancient
Babylon; and that under the wide mouth of the harbour at Marseilles
(a much more difficult work); show that the ancients were beforehand
with us in the art of tunnelling。 Macadamized roads are as old as the
Roman empire; and suspension bridges; though comparatively new in
Europe; have been known in China for centuries。
There is every reason to believeindeed it seems clear that the
Romans knew of gunpowder; though they only used it for purposes of
fireworks; while the secret of the destructive Greek fire has been
lost altogether。 When gunpowder came to be used for purposes of war;
invention busied itself upon instruments of destruction。 When
recently examining the Museum of the Arsenal at Venice; we were
surprised to find numerous weapons of the fifteenth and sixteenth
centuries embodying the most recent English improvements in arms;
such as revolving pistols; rifled muskets; and breech…loading cannon。
The latter; embodying Sir William Armstrong's modem idea; though in a
rude form; had been fished up from the bottom of the Adriatic; where
the ship armed with them had been sunk hundreds of years ago。 Even
Perkins's steam…gun was an old invention revived by Leonardo da Vinci
and by him attributed to Archimedes。*

The Congreve rocket is said to have an Eastern origin; Sir William
Congreve having observed its destructive effects when employed by the
forces under Tippoo Saib in the Mahratta war; on which he adopted and
improved the missile; and brought out the invention as his own。
Coal…gas was regularly used by the Chinese for lighting purposes long
before it was known amongst us。 Hydropathy was generally practised by
the Romans; who established baths wherever they went。 Even chloroform
is no new thing。 The use of ether as an anaesthetic was known to
Albertus Magnus; who flourished in the thirteenth century; and in his
works he gives a recipe for its preparation。 In 1681 Denis Papin
published his Traite des Operations sans Douleur; showing that he had
discovered methods of deadening pain。 But the use of anaesthetics is
much older than Albertus Magnus or Papin; for the ancients had their
nepenthe and mandragora; the Chinese their mayo; and the Egyptians
their hachisch (both preparations of Cannabis Indica); the effects of
which in a great measure resemble those of chloroform。 What is
perhaps still more surprising is the circumstance that one of the
most elegant of recent inventions; that of sun…painting by the
daguerreotype; was in the fifteenth century known to Leonardo da
Vinci;*

whose skill as an architect and engraver; and whose accomplishments
as a chemist and natural philosopher; have been almost entirely
overshadowed by his genius as a painter。*

Mr。 Hallam; in his Introduction to the History of Europe; pronounces
the following remarkable eulogium on this extraordinary genius:
〃If any doubt could be harboured; not only as to the right of
Leonardo da Vinci to stand as 'the first name of the fifteenth
century; which is beyond all doubt; but as to his originality in so
many discoveries; which probably no one man; especially in such
circumstances; has ever made; it must be on an hypothesis not very
untenable; that some parts of physical science had already attained a
height which mere books do not record。〃 〃Unpublished MSS。 by Leonado
contain discoveries and anticipations of discoveries;〃 says Mr。
Hallam; 〃within the compass of a few pages; so as to strike us with
something like the awe of preternatural knowledge。〃

The idea; thus early born; lay in oblivion until 1760; when the
daguerreotype was again clearly indicated in a book published in
Paris; written by a certain Tiphanie de la Roche; under the
anagrammatic title of Giphantie。 Still later; at the beginning of the
present century; we find Thomas Wedgwood; Sir Humphry Davy; and James
Watt; making experiments on the action of light upon nitrate of
silver; and only within the last few months a silvered copper…plate
has been found amongst the old household lumber of Matthew Boulton
(Watt's partner); having on it a representation of the old premises
at Soho; apparently taken by some such process。*
