ing the sounds which were

      'sealed in crystal silence there。'

The first was a piece which had been played on the piano; quick time; and the fidelity and loudness with which it was delivered by the hearing tube was fairly astonishing; especially when one considered the frail and hair…like trace upon the wax which had excited it。 There seemed to be something magical in the effect; which issued; as it were; from the machine itself。 Then followed a cornet solo; concert piece of cornet; violin; and piano; and a very beautiful duet of cornet and piano。  The tones and cadences were admirably rendered; and the ear could also faintly distinguish the noises of the laboratory。  Speaking was represented by a phonogram containing a dialogue between Mr。 Edison and Colonel Gouraud which had been imprinted some three weeks before in America。  With this we could hear the inventor addressing his old friend; and telling him to correspond entirely with the phonograph。 Colonel Gouraud answers that he will be delighted to do so; and be spared the trouble of writing; while Edison rejoins that he also will be glad to escape the pains of reading the gallant colonel's letters。 The sally is greeted with a laugh; which is also faithfully rendered。

One day a workman in Edison's laboratory caught up a crying child and held it over the phonograph。 Here is the phonogram it made; and here in England we can listen to its wailing; for the phonograph reproduces every kind of sound; high or low; whistling; coughing; sneezing; or groaning。  It gives the accent; the expression; and the modulation; so that one has to be careful how one speaks; and probably its use will help us to improve our utterance。

By speaking into the phonograph and reproducing the words; we are enabled for the first time to hear ourselves speak as others hear us; for the vibrations of the head are understood to mask the voice a little to our own ears。  Moreover; by altering the speed of the barrel the voice can be altered; music can be executed in slow or quick time; however it is played; inaudible notes can be raised or lowered; as the case may be; to audibility。  The phonograph will register notes as low as ten vibrations a second; whereas it is well known the lowest note audible to the human ear is sixteen vibrations a second。  The instrument is equally capable of service and entertainment。  It can be used as a stenograph; or shorthand…writer。  A business man; for instance; can dictate his letters or instructions into it; and they can be copied out by his secretary。 Callers can leave a verbal message in the phonograph instead of a note。  An editor or journalist can dictate articles; which may be written out or composed by the printer; word by word; as they are spoken by the reproducer in his ears。

Correspondence can be carried on by phonograms; distant friends and lovers being able thus to hear each other's accents as though they were together; a result more conducive to harmony and good feeling than letter…writing。  In matters of business and diplomacy the phonogram will teach its users to be brief; accurate; and honest in their speech; for the phonograph is a mechanical memory more faithful than the living one。  Its evidence may even be taken in a court of law in place of documents; and it is conceivable that some important action might be settled by the voice of this DEUS EX MACHINA。  Will it therefore add a new terror to modern life?  Shall a visitor have to be careful what he says in a neighbour's house; in case his words are stored up in some concealed phonograph; just as his appearance may be registered by a detective camera?  In ordinary lifeno; for the phonograph has its limitations; like every other machine; and it is not sufficiently sensitive to record a conversation unless it is spoken close at hand。 But there is here a chance for the sensational novelist to hang a tale upon。

The 'interviewer' may make use of it to supply him with 'copy;' but this remains to be seen。  There are practical difficulties in the way which need not be told over。  Perhaps in railway trains; steamers; and other unsteady vehicles; it will be…used for communications。  The telephone may yet be adapted to work in conjunction with it; so that a phonogram can be telephoned; or a telephone message recorded in the phonograph。 Such a 'telephonograph' is; however; a thing of the future。  Wills and other private deeds may of course be executed by phonograph。  Moreover; the loud…speaking instrument which Edison is engaged upon will probably be applied to advertising and communicating purposes。  The hours of the day; for example; can be called out by a clock; the starting of a train announced; and the merits of a particular commodity descanted on。  All these uses are possible; but it is in a literary sense that the phonograph is more interesting。  Books can now be spoken by their authors; or a good elocutionist; and published in phonograms; which will appeal to the ear of the 'reader' instead of to his eye。  'On; four cylinders 8 inches long; with a diameter of 5;' says Edison; 'I can put the whole of NICHOLAS NICKLEBY。' To the invalid; especially; this use would come as a boon; and if the instrument were a loud speaker; a circle of listeners could be entertained。  How interesting it would be to have NICHOLAS NICKLEBY read to us in the voice of Dickens; or TAM O' SHANTER in that of Burns!  If the idea is developed; we may perhaps have circulating libraries which issue phonograms; and there is already some talk of a phonographic newspaper which will prattle politics and scandal at the breakfast…table。  Addresses; sermons; and political speeches may be delivered by the phonograph; languages taught; and dialects preserved; while the study of words cannot fail to benefit by its performance。

Musicians will now be able to record their improvisations by a phonograph placed near the instrument they are playing。  There need in fact be no more 'lost chords。' Lovers of music; like the inventor himself; will be able to purchase songs and pieces; sung and played by eminent performers; and reproduce them in their own homes。  Music… sellers will perhaps let them out; like books; and customers can choose their piece in the shop by having it rehearsed to them。

In preserving for us the words of friends who have passed away; the sound of voices which are stilled; the phonograph assumes its most beautiful and sacred character。  The Egyptians treasured in their homes the mummies of their dead。  We are able to cherish the very accents of ours; and; as it were; defeat the course of time and break the silence of the grave。 The voices of illustrious persons; heroes and statesmen; orators; actors; and singers; will go down to posterity and visit us in our homes。  A new pleasure will be added to life。  How pleasant it would be if we could listen to the cheery voice of Gordon; the playing of Liszt; or the singing of Jenny Lind!

Doubtless the rendering of the phonograph will be still further improved as time goes on ; but even now it is remarkable ; and the inventor must be considered to have redeemed his promises with regard to it。 Notwithstanding his deafness; the development of the instrument has been a labour of
