novel kind Of telegraph, the invention Of Signor
Guattari, an Italian, was submitted TO the inspec.

The inventor aims at obtaining by the use OF atmos-
phero power the same or better results than those
attained by electric and magnetic forces. TO this
end he charges O reservoir with compressed air,
and by the operation Of valves worked in the same
manner as those IN use IN the ordinary telegraph
system, sends pulsatons through tube, which
pulsauons are made TO work upon the receiving
Instrument with an effect corresponding with
insulated wires. The invention has been 80 July
recognized by the Royal Institution OF Naples that
they nave paid to Sgnor Guattari the rare compli-
ment OF awarding him gold medal. 1t is further
reported that the system Is to be generally adopted
on board the Italian ships OF war Tor tho TRANSMITS
sion OF orders from the commanding officer to sub.
ordinate departments.

on the apparatus for communicating with various
parts Of snip, and subsequently with what may be
called the domestic telegraph. In this case Signor
Guattari dispensed with the use Of the reservoir,
and, by mere manipulation Of an air ball at the end
OF a tube recorded true cipher characters

over the small Wheels Of the receiving in.

pendent or foreign aid is less likely to get out Of
order than wires conducting electric currents, and
Will not be more expensive. For longer distances,
OH regular public lines, the invention would probably
not apply so WELL or work rapidly, the present
tclegraphs. The inventor Is, however, equally sam
gulne In this in smaller branches, and Claims not
without reason, that his apparatus will be less eX-
pensve than electric batteries and will be less SUBJ
ject to the influence Of those atmospheric storms
which sometimes put The telegraphic system Of q

signor Guattari was heartily congratulated on the
performance or his apparatus. The now telegraph
