TATTOoNG.-1he London Lancet says: The
subject of tattooing has acquired temporary interest
from the incidents OF the Tchborne trial The practice
Is OF great antiquity and, well known, is adopted
by many savage tribes the mode in which 1t Is per-
formed however, varies considerably. Thus while the
Australian makes deep ineisons, and fills in the wound
with clay and other substances that an elevated scar
is left the New-Zcalander scarifes himself with an
instrument resembling a curry-c0mb, constructed OF
sharks teeth which slowly driven through the skin
by repeated blows Of a mallet the wounds being filled
with the resin Of the Kaur pine and kind OF red earth

tribes tattooing il unques,onably used substitute
for clothing and Prchard, as quoted by Wood in his
History Man, observes that European eyes become
accustomed 10 the tattoo that they rather shocked at
its absence; and so completely is this feeling realized
by the natives, that chefs VINO nave arrived AT

TEMPERATURE OF THE SUN.-Ina cOmmunica-
ton to the Paris Academy Of Sciences high tempera
tures St. Claire Deylle holds that the temperatures
produced and assured in chemical laboratories not
far surpassed in Nature To speak Of the surface Of the
sun is suppose that it resembles redhot ball To
speak the temperature at the surface of the solar
atmosphere is to suppose that such atmosphere is
bounded abruptly by ncandescent layer. Lastly TO
calculate the temperature at of the Suns mass
by phoometrc acnometric. other modes OF measure
meut absolutely to neglect the effect OF the very
possibly extended Layer of nonlumnous solar matter
which, according to all appearances is superposed the
incandescent layer, and whose radiation toward the
earth is thus neglected. All such calculations relate
only the quantity OF heat emitted from the whole Sun,
and TO the temperature at its surface Deyle sug
gests a method by which, perhaps, the question he
approached The lines OF hydrogen emitted from certain
pots OF the glowing solar matter are determined by
astronomical observations. Frankand and Lociyer have
found these lines in hydrogen subjected to certain
pressure. We might determine the temperature OF the
Combustion OF hydrogen at this pressure and conse-
Quently the temperature and pressure OF the
those points Of the solar atmosphere where these hydro
Gen lines have been observed Deyies inyesg cations
thus far have led him TO the conclusion that the tempera
ure Of the sun Is about three or four times the melting
temperature OF planum-that is 10 say about 6,Oo0 10
5000 ccntigrade Mr. Naule has by ingenious theory
been led 10 TX the temperature at 10000 centigade
F1Zcau has solved the problem by another method ::
the intensity OF light, he compares the solar light with
that produced by the carbon points OF the electric light
at the conclusion that the temperature Of the sun
about $1,000 centgrade.
