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。*
