wires ara another aud important discovery Of Mr..
Meram's, communicating 10 him information OF
any earthquake that takes place IN any part OF the
world They are termed, as above, mcteOric
magnetic and electric wires. They consist in part
of two vertical wires. whose lower ends pass
through pool of salt water into the ground
These iptersect each other, one pointing 10 the y.
Z. the other 10 the :. w the range of which is
the direction of the electric current. SurmOuntng
each is a long metallic tube lined with copper
These tubes receive the electric action OF the at
mosphere aud the ground ends of the wires receive
the magnetic action of the earth, which combine
From these wires run two horizontal wires, which
meet at point and support native loadstone,
from which descend two united wires % the bulb OF
a thermometer; the action upon the mercury IN
which indicates the AERIAL or terrestrial disturbance,
bv showing the equlllbratOns above described
Earthquakes, Mr.. NJ. says are always attended by
thunder and lightning, remote or near. IL "a his
opinion that all rains produced by earthquakes,
or as he sometimes dcuOminates them, tremOrs Of
the earth; which may or may not be felt, but
which are cont uous ~ the regiOn Of the rain I;
andthatthe same earthquakes cause always SHOWS
IN remote northern religions, or high southern Gle
vatons
We conclude with an interesting fact, also {,
recent discovery of Mr. Meriam's viz: that the
earth freezes when the air may be ut a tempera-
ture of 3j2. He says 1.-The temperature OF the air
l23d and oath of February was 3J2 by range OF
3 thermometers 10 feet above the ground. The air
had not been as low as 322 for "a hours prior to
the morning of the 23d and for II hours sue
ceeding the morning OF the . It'll at sunrise. On
both these mornings ice made freely upon the
ground aud the surface of the earth was frozen"
Ii will be understood that the air alone at $50
and that the earth was at the freezing point In
confirmation of this Mr. NJ. publishes the following
notice by traveller in the Province of Tuscany. Ia
Italy, IN the year lsls but which had not met his
eve nj the time OF his making the discovery.
Winter by far IS the finest season at Pisa, and
fully as mild as our Spring The east wind, in
deed, being screened only by the Nerrucola, is eK
ceediney sharp. and freezes at 359." This unusual
state OF the atmosphere Mr. NJ. thinks occurs only
during am earthquake. The instance which be
has recorded was attended by an earthquake, and
By heavy thunder storm at high elevation at
distance.
Il was not mentioned above that the equilibra-
tons also sometimes occur in t'giRsthe one shock
indicated by them being the response Of the other.
A pow erful shock always produces such a reaction.
We have only alluded 10 the phenomena which
attend the cVcies and eguiilbr0fioH,. Mr.. NJ has
particular account Of an storms and other meteo-
rological occurrences which took place over the
country during their existence or attending them,
so far as be has correspondents. And his records
of earthquakes are proved by corresponding &C
counts OF the same, In the papers. 50 TAR ~ such
have been published; and by letters from cores
pondenfs who were AT the scene of the occurrence.
