Geographical statistics show that If
ty-two volcanic islands have risen out
of the sea since the beginning Of the
century. Nineteen of that number have
since disappeared, and ten are now In.
habited.
The fruit OF the nutmeg tree is pear
shaped. 1t consists Of four parts.
1eshy outer part, red network within
this, known to commerce as mace, tue
shell covered by the mace. and the
kernel, or nutmeg proper.
1t is well known that anesthetics, es
peclally chloroform and ether, are fatal
to living beings, acting slowly when
they are used in small quantities for
long time, and rapidly when they ere
given In large doses. This is true both
FOR animal and for vegetable life.
Fat, or the materials dissolved from
a feeding stuff by ether, is substance
Of mixed character, and may include,
besides real fats, wax, the green col
oring matter Of plants, etc. The fat Of
food is either stored up in the body
as fat or burned, to furnish heat and
energy.
Powdered sugar Is said to possess de-
cided inferior sweetening properties to
those of the coarsely crystalllzed arti-
Gle. In the process Of pulverization 1t
is claimed that the heat and electricity
produced transform certain proper
tion Of the sugar into glucose, whose
sweetening powers are two and o half
times less than those of saccharose.
The lung differs from all other struc-
lures In having two separate circula-
tions, the nutritive, supplied by the left
side of the heart through the bronchial
arteries; and the functional, supplied
by the right side of the heart through
the pulmonary artery. This double cir
culation underlies all the phenomena of
pneumonia, and must be recognized In
any definition of the disease, as with
out 1t the disease itself cannot exist.
Our new island Of Porto Rico, ac-
cordlng to Mark w. Harrington, is "the
most densely populated rural COM
munity proper in America" 1t has
about 22G inhabitants to the square
mile. When the SpanIards first occu-
pied 1t, 1t was as densely populated as
1t is now. Before Columbus discovered
America two successive races had oc-
cupied the island; one seems to have
been of northern origin and the other
was Of Carib stock. Every tillable part
of the land has been cultivated again
and again.
Among the flint, quartz and jasper ar
row-heads frequently found In this
country are certain forms known to
archaeologlsts as "war points" For
arrows they were made small, some
times not more than three-fifths of an
inch long. They are triangular In out
line, and were intended to stick fast In
II wound. Prof w. X. Moorehead says
that war points are found abundantly
scattered In certain localities where
there are no indications of villages hav-
ing existed, and the inference Is that
such places were backgrounds, where
the red men fought In ancient days.
For many years efforts have been
made from time to time to measure the
heat radiated from some OF the bright
est stars. The most successful attempt
appears to be that of Professor Nichols
at the Yerkes Observatory. With the
ala Of an apparatus recalling the prin-
ciple of the Crookes radiometer, he has
ascertained that the star Vega, which
shines very brilliantly near the zenith
in midsummer evenings, sends to the
earth an amount of heat equal to that
of an ordinary candle six miles distant.
Arcturus, the star celebrated by Job,
and which has a somewhat fiery color,
radlates about twice as much heat as
VegR.
