Worth While Working Out.
To the questions in issue of Dec 9, num-
bered Il to 80, the following responses were
received: Harry T. Matthews Kinsman, o.,
answered ~, n and 70 correctly The an
swer to 70 gave the definition of saccbarine
as sweet" Thisrfs correct, but not the an
swer which was intended to be elected. Asa
W. Slayton, Co. B, 225th Mich, Grand Rapids,
Mich, answered correctly II to 80. The
answer to 10 IS correct. LeucOcytes occur
only in the animal system, but the wording
of the answer would indicate more extern
sive occurrence.
II. Chlorophyll, the chemical elements not
determined yet, is that which gives the green
color to leaves and plants; only found in
plants growing in light.-Asa w. SlaytOn.
1t is noted that the elements" of which
chorophyll is composed are well known, being
those which form all other vegetable and
animal matter, viz carbon. hydrogen, nitro
gen, and oxygen, with some ash constituents.
Its composition" in other words, the way
in which these elements are arranged, is not
known at present.
70 Minium is made by taking the pellicle
which forms in melted lead and exposing to
more intense heat 1t becomes deep yellow
and forms massicot' The latter slowly
heated in air assumes deep-red color and
becomes minimum. Harry r. Matthews Min
ium is red lead or red oxide of lead; con-
sist ing 3l2 parts of lead to 81 of oxygen by
weight 1t is much used in the manufacture
of glass and in painting.-Asa W. Slayton.
Is An electrical current passing through
wire makes a compass needle in its vicinity
assume position at right angles to the wire
bIIrt no Int laH
the needle, strengthen the needle, reverse the
poles, or destroy its polarity.-Asa w. Stay
ton.
Il A Grenet cell is plate of zine sus-
pended between two carbon plates in glass
bottle containing water, potassium bichro-
male and sulphuric acid.-Asa w. Slayton.
10 Leucocytes are the white blood cor
puscles. They have the power of am9bod
movement, and by the recent doctrine of
"phagOcytOss " have the function of sur
rounding and digesting any foreign bodies,
such as bacteria, which may get into the
blood
IS. Levulose is a soft sugar abundant in
honey and some fruits. 1t seldom crystal
lizes.-Asa w. Slayton. 1t is somewhat
swecter than cane-sugar. 1t is sold on the
market under the title of 'tdiabetine,"
being supposed to be peculiarly suited to dia-
bette patients. When honey candies, +" the
granules separating out are crystals of dex-
trose, while the strip in which they are found
IS largely levulose sirup.-Ed.
II. There are 206 bones in the human
body now. There used to be 20S when they
counted four in each ear-Asa W. Slayton
IS. The longest bone in the body is the
femur, which extends from hip to knee-Asa
w. Slayton.
z,.I. L.
IN commerce Anything sweet or sugary-
Asa W. Slayton. Benzoic sulphinide is a
preparation made from coal tar and discovered
in Baltimore, eight or ten years ago. 1t is
200 to 400 times as sweet as the same weight
of sugar. The proportion depends some
what on the imagination of the faster The
larger figure is as far as the manufacturers
claims have gone 50 far. 1t is not food but
is probably perfectly harmless. Ed.
so. Muntz metalP is an alloy of about
60 per cent. copper and 40 per cent. zine. 1t
is used to sbeathe' vessels, as salt water cor
rodes iron.-Asa ". Slayton.
