Cincinnati, specimens Of recording by his Electro
Magnetic Clock which entirely iulhs all the condi-

When the first discoveries In Electro Magnetism
made II might have been pronounced, at least
improbable that practical Astronomy would benefit by
tholr development The application, so described by
Mr. Walker, is new instance OF mutual relations tc'

The report Of Assistant w alker gives a descnp-
ton Of the process OF the invention by Dr. Locke OF
Cincinnati, and enumerstes all It's advantages
An Astronomical clock, without injury 10 ts rate
graduates the seconds Of time in the shape OF lines with
short interruptions the end the running hue, of
paper Of MpTsee Electro Magnetic Telegraph IL may |
be used line Of any length a. pleasure. The clock
and astronomer may be thousand miles apart lie !
prints the date Of sny Astronomical event by tapping
brsak circuit Key, and mprints small bTsak circuit
space on the registering line OF seconds.
The report mentions the number OF aires that may
be used IN instrument by The survey
process. Ihcy amount 60 some nine or more TALES
distinct groups OF hve wires 10 each. Each tally il |
printed quicker and better than single wire be
observed IN the common way catalogue of right as
tensions OF stars like those made Out of years
ulsed abors At the royal observatory of Greenwich
he turned out by the process equally
well In year.
Where single wire per nishi is used AT Munich,
Bonn aud Washington. tally may be printed in the |
same tne and the catalogue OF risht ascensions will
be- worth some i've times much those being
made ut such establishments
The printed record never has any clerical errors
After the nights work Is finished the hiet which is
wound the receiving reel IS labeled end filed away
as permanent book Of original printed entries
In telegraph operations for longitude star pass
ing two stations, aud having s passage over the
printed the register, will, hen they
several thousand mies apart give lou gitude we'll
that of Greenwich snd Paris known, after some
two centuries Of comparisons.
The national enterprise 10 Chill under Lieut. Giluss
L. :. n. may by this method acquire tenold the
ordinary value by measuring distance from the sun
through the transit 81 Mars and star esst
and west OF the meridian.
Whenever right sscensions stars or other heavenly
bodies are observed. nights wears work BY
the cosstsurvey method may take the place OF ten
