PREFACE 



VERY little is known at present about the telegraphy 

 of pictures, because -the published descriptions of the * 

 instruments in use have been confined almost entirely 

 to technical journals. The desire to have news at 

 the earliest possible moment, and the recent demand 

 by the public to have the " news in pictures," has 

 opened up the field for a new science, which is a 

 peculiar mixture of electricity, optics and photo- 

 engraving. The telegraphed picture, at first looked 

 upon as a marvel, now occasions little or no surprise, 

 which means that it is sufficiently like an ordinary 

 photograph to pass muster among the other pictures 

 in the newspaper in which it appears. 



During the last two-and-a-half yeajrs, a great deal 

 of experimental work has been carried out by me for 

 The Daily Mirror, and it has been very largely 

 owing to the active interest this journal has shown 

 in photo-telegraphy that the pioneer work in this 

 country has been possible. The interest displayed 

 in the work by the editor, Mr. Alex. Kenealy, has 

 never failed, and to his encouragement and enter- 

 prise the present position of this new branch of 

 telegraphic work is largely due.
