A long and interesting paper on "Prac-
zeal Aspects of Printing Telegraphy" by
ar Donald Murray read before the British
institution of Electrical Engineers, dealt
generally with the field for printing teieg-
Apply; with the practical difficulties in
he way OF printing teegraphy; and with
ONE printing telegraph apparatus designed
o overcome these difficulties. So far as
he present position OF printing telegraphs
vas concerned, the author said that the
hughes tape printer carried the bulk Of the
telegraph traffic on the continent Of Eu-
ope. and II had done so for nearly half
century, about 5000 Hughes instruments
,eing now In use. Most OF the telegraph
rattle between Great Britain and the con-
inent was also carried by the Hughes,
ut this machine was employed outside Of
europe only to very slight extent. Dur
ng the last thirty years the Baudot system
which might be described as a multiplied
hughes tape printer, had been developed
nd extended In France until all the tele-
raph lines OF any Importance We're

Great Britain had so far only coquetted

onged fIirtations having been carried on

automatic the siemens and Haiske, and
everal other systems. The latest arrival,
he Murray multplex, might be described
$ the child OF the British postoffice, 1t

nee OF that institution. The Murray au-
omatic system had made more progress
" to the present in Germany. 1t had also

Results Unsatisfactory.
m spite OF the activity of printing tele-
raph inventors, the substantial results
we're neither extensive nor brilliant and
