Within a radius of S3 miles of New

$500. 900 people and $4,000 telephones
IN New York city proper there arc TO-
500 telephone sta tions, 90 per cent of

crates 10 central exchanges, seven of
which are entirely for metallic circuit
service. The New York & New Jersey
Telephone Co. has 10000 subscribers.

An improved multiple telee11phic
instrument has been introduced into
France, in which each kew sends over
the line wire at each operation en- in
termlttent current corresponding to a
definite number of vibration a minute.
The receiving saunders are each in a
similar way sensitive only to currents
having determined rate of vibrations
corresponding to one of the Transmits
ting keys. Consequently each receiver
selects and responds to the current
sent by transnitter having a CORE
spending period of vibra tions.
"A new telephone system IS said to

y 1t is proposed to place telephones
in several places easy of access, where
who wishes to send a notice or
a paid advertisement to any of the AL
bany papers can do SO with very little
trouble. The plan was submitted
Some time ago to several OF the news
papers of Albany. 1t has been pro-
posed to place these instruments in
branch offices, in stationery or drug
stores, in remote parts Of the city and
suburbs. The Office will be kept open
Ill day and until late at night. The |
promoters of the scheme have tested |
i've telephones connected with a mile
wire with satisfactory results, viz: the
Phoenix, Harrison, D'Ungcr, National

1t this moment the operator turns on
current, of which the intensity is
radually increased till it has obtained
he utmost limit that the patient can
import. The extractor is then put in
