again。 In the midst of his confusion; it seemed like satire to him to hear the commissioners say; as they smiled all round; and bowed themselves gracefully off; 'TRES… BIEN; MONSIEUR HUGHESTRES…BIEN; JE VOUS FELICITE。' But the matter was explained next morning; when Professor Hughes learned that the transmitting clerk at Lyons had been purposely instructed to earth the line at the time in question; to test whether there was no deception in the trial; a proceeding which would have seemed strange; had not the occurrence of a sham trial some months previous rendered it a prudent course。 The result of this trial was that the French Government agreed to give the printer a year of practical work on the French lines; and if found satisfactory; it was to be finally adopted。 Daily reports were furnished of its behaviour during that time; and at the expiration of the term it was adopted; and Professor Hughes was constituted by Napoleon III。 a Chevalier of the Legion of Honour。
The patronage of France paved the way of the type…printer into almost all other European countries; and the French agreement as to its use became the model of those made by the other nations。 On settling with France in 1862; Professor Hughes went to Italy。 Here a commission was likewise appointed; and a period of probationonly six monthswas settled; before the instrument was taken over。 From Italy; Professor Hughes received the Order of St。 Maurice and St。 Lazare。 In 1863; the United Kingdom Telegraph Co。; England; introduced the type…printer in their system。 In 1865; Professor Hughes proceeded to Russia; and in that country his invention was adopted after six months' trial on the St。 Petersburg to Moscow circuit。 At St。 Petersburg he had the honour of being a guest of the Emperor in the summer palace; Czarskoizelo; the Versailles of Russia; where he was requested to explain his invention; and also to give a lecture on electricity to the Czar and his court。 He was there created a Commander of the Order of St。 Anne。
In 1865; Professor Hughes also went to Berlin; and introduced his apparatus on the Prussian lines。 In 1867; he went on a similar mission to Austria; where he received the Order of the Iron Crown; and to Turkey; where the reigning Sultan bestowed on him the Grand Cross of the Medjidie。 In this year; too he was awarded at the Paris Exhibition; a grand HORS LIGNE gold medal; one out of ten supreme honours designed to mark the very highest achievements。 On the same occasion another of these special medals was bestowed on Cyrus Field and the Anglo…American Telegraph Company。 In 1868; he introduced it into Holland; and in 1869; into Bavaria and Wurtemburg; where he obtained the Noble Order of St。 Michael。 In 1870; he also installed it in Switzerland and Belgium。
Coming back to England; the Submarine Telegraph Company adopted the type…printer in 1872; when they had only two instruments at work。 In 1878 they had twenty of them in constant use; of which number nine were working direct between London and Paris; one between London and Berlin; one between London and Cologne; one between London and Antwerp; and one between London and Brussels。 All the continental news for the TIMES and the DAILY TELEGRAPH is received by the Hughes' type…printer; and is set in type by a type…setting machine as it arrives。 Further; by the International Telegraph Congress it was settled that for all international telegrams only the Hughes' instrument and the Morse were to be employed。 Since the Post Office acquired the cables to the Continent in 1889; a room in St。 Martin's…le…Grand has been provided for the printers working to Paris; Berlin; and Rome。
In 1875; Professor Hughes introduced the type…printer into Spain; where he was made a Commander of the Royal and Distinguished Order of Carlos III。 In every country to which it was taken; the merits of the instrument were recognised; and Professor Hughes has none but pleasant souvenirs of his visits abroad。
During all these years the inventor was not idle。 He was constantly improving his invention; and in addition to that; he had to act as an instructor where…ever he went; and give courses of lectures explaining the principles and practice of his apparatus to the various employees into whose hands it was to be consigned。
The years 1876…8 will be distinguished in the history of our time for a triad of great inventions which; so to speak; were hanging together。 We have already seen how the telephone and phonograph have originated; and to these two marvellous contrivances we have now to add a third; the microphone; which is even more marvellous; because; although in form it is the simplest of them all; in its action it is still a mystery。 The telephone enables us to speak to distances far beyond the reach of eye or ear; 'to waft a sigh from Indus to the Pole; 'the phonograph enables us to seal the living speech on brazen tablets; and store it up for any length of time; while it is the peculiar function of the microphone to let us hear those minute sounds which are below the range of our unassisted powers of hearing。 By these three instruments we have thus received a remarkable extension of the capacity of the human ear; and a growth of dominion over the sounds of Nature。 We have now a command over sound such as we have over light。 For the telephone is to the ear what the telescope is to the eye; the phonograph is for sound what the photograph is for light; and the microphone finds its analogue in the microscope。 As the microscope reveals to our wondering sight the rich meshes of creation; so the microphone can interpret to our ears the jarr of molecular vibrations for ever going on around us; perchance the clash of atoms as they shape themselves into crystals; the murmurous ripple of the sap in trees; which Humboldt fancied to make a continuous music in the ears of the tiniest insects; the fall of pollen dust on flowers and grasses; the stealthy creeping of a spider upon his silken web; and even the piping of a pair of love…sick butterflies; or the trumpeting of a bellicose gnat; like the 'horns of elf…land faintly blowing。'
The success of the Hughes type…printer may be said to have covered its author with titles and scientific honours; and placed him above the necessity of regular employment。 He left America; and travelled from place to place。 For many years past; however; he has resided privately in London; an eminent example of that modesty and simplicity which is generally said to accompany true genius。
Mechanical invention is influenced to a very high degree by external circumstances。 It may sound sensational; but it is nevertheless true; that we owe the microphone to an attack of bronchitis。 During the thick foggy weather of November 1877; Professor Hughes was confined to his home by a severe cold; and in order to divert his thoughts he began to amuse himself with a speaking telephone。 Then it occurred to him that there might be some means found of making the wire of the telephone circuit speak of itself without the need of telephones at all; or at least without the need of one telephone; namely; that used in transmitting the sounds。 The distinguished physicist Sir William Thomson; had lately discovered the peculiar fact that when a current of electricity is passed through a wire; the current augments when the wire is extended; and diminishes when the wire is compressed; because in the former case the resistance of the material of the wire to the passage of the current is lessened; and in the latter case it becomes greater。
Now it occurred to Professor Hughes that; if this were so; it might be possible to cause the air…vibrations of sound to so act upon a wire conveying a current as to stretch and contract it in sympathy with themselves; so that the sound…waves would create corresponding electric waves in the current; and these electric waves; passed through a telephone connected to the wire; would cause the telephone to give forth the original sounds。 He first set about trying the effect of vibrating a wire in which a current flowed; to see if the stretching and compressing thereby produced would affect the current so as to cause sounds in a telephone connected up in circuit with the wirebut without effect。 He could hear no sound whatever in the telephone。 Then he stretched the wire till it broke altogether; and as the metal began to rupture he heard a distinct grating in the telephone; followed by a sharp 'click;' when the wire sundered; which indicated a 'rush' of electricity through the telephone。 This pointed out to him that the wire might be sensitive to sound when in a state of fracture。 Acting on the hint; he placed the two broken ends of the wire together again; and kept them so by the application of a definite pressure。 To his joy he found that he had discovered what he had been in search of。 The imperfect contact between the broken ends of the wire proved itself to be a means of transmitting sounds; and in addition it was found to possess a faculty which he had not anticipatedit proved to be sensitive to very minute sounds; and was in fact a rude microphone。 Continuing his researches; he soon found that he had discovered a prin… ciple of wide application; and that
