The tympanum T is that which is used for recording the sounds, and M is a mouthpiece, which is fixed to it for speaking purposes. The other tympanum, T', reproduces the sounds; and E E is a branched ear-piece, conveying them to the two ears of the listener. The separate wax tube, P, is a phonogram with the spiral trace of the sounds already printed on its surface, and ready for posting.
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.
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.
The instrument wrote, so to speak, different hands under my voice and under Esmo's; and those who knew him could identify his phonogram, as my friends my manuscript.
Each instrument, as we have seen, can be employed for receiving as well as recording; and as all are made to one pattern, a phonogram coming from any one, in any art of the world, can be reproduced in any other instrument. A little box with double walls has been introduced for transmitting the phonograms by post.
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.
Such a record or phonogram, as it was then called, could be removed from the machine or replaced at any time, many reproductions could be obtained without wearing out the record, and whenever desired the record could be shaved off by a turning-tool so as to present a fresh surface on which a new record could be formed, something like an ancient palimpsest.
Like Ampere, too, he was noted for a memory which retained many of the facts thus impressed upon it, as the sounds are printed on a phonogram. The boy student was also a keen man of business, and his pursuit of knowledge in the evening did not sap his enterprises of the day. He soon acquired a virtual monopoly for the sale of newspapers on the line, and employed four boy assistants.
In the same caveat he describes an invention whereby the power to indent on a phonograph cylinder, instead of coming directly from the voice, is caused by power derived from the rotation or movement of the phonogram surface itself. He did not, however, follow up this invention and put it into practice. Some twenty years later it was independently invented and patented by another inventor.
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.
