AFTER DINNER MAPS.
Many persons, particularly the mid
dle-aged and elderly, allow themselves
after-dinner maps; and the custom i
not carried to excess, is by many med.
ical men considered beneficial ratber
than otherwise, as by keeping the BODY
in state of quietude, digestion Is
promoted and assisted. In southern
countries the midday sleep, termed
the Siestd, is almost universally taken
and wonderfully refreshes the frame
enervated and weakened by the intense
heat. 1t is, however, recommended
that such sleep be not INDUCED in To
too great length, as persons invariably
find such prolonged slumber in the day.

sanetioning the indulgence, particular
ly desire that it be taken in a reclining
posture, and by no means lying
horizontally, the stomach in the latter
position pressing on the intestines, and
causing the blood to be impelled to the
head. Corpulent persons, and those
who have a tendency to apoplexy,
should be particularly mindful ON this
point.
cANSIBAL STATISTICS.
The cannibals are more numerous
than is generally supposed. The Bat
tas are reckoned at 300, 900 souls; the
cannibals of Niger Delta at 100, 900;
the Fans of $4,000; the cave jewellers
of the Bassuto country, about tenth
of the whole population-at 10000; the
Nam Mans at about 500, 900; the Mi
ranhas and Messaysas at 5000 the
other southern African cannibals at
1000; the Australian aborigines at 80.
900; the Milanesian without including
New Guinea, at 1000, 200. Ii per-
son choose to run the risk of being
eaten, here is a wide choice. Most Of
these people, however, it must be re-
membered, are not cannibals except in
time of war, when it is more ancestral
custom which makes them etlectually
dispose of an enemy by eating him.
PATENT BRAIN DROPS.
Psychologists tell us that the brain
consumes a great deal of phosphorus,
and the doctors say that brown bread
is healthier than that made from bolted
-four, because of the phosphorus that
the bran contains, which in fine -four is
in great part absent. Baking powders
were accordingly invented, the prlncl.
pie purpose of which is to supply bread
with the needful amount of the phos-
phoric quality. a candy has now been
invented and patented, which is moth
ing else than doses of phosphorus IN
disguise. The love of candy has thus
been utilized and made to repair the
waste of nervous and brain forces. 1t
is pleasant way of taking medicine,
and even the children cry for it.
PURE AIR.
DR.. August Smith gives a good rule
for ascertaining the amount OF carbon
ic acid in the air of the house: Let
us keep our room SO that the air does
not give a precipitate when lOl ounce
bottleful is shaken with half an ounce
of clear lime water" a sanitary regu'
lation which can easily be carried out
CONDUCTORS OF SOUND.
Among the best conductors of sound
are iron and glass. Through them
sound is transmitted at the rate OF IL
500 feet, over three miles per second.
But in air SQUAD travels only thirteen
miles per minute, or l, l42 feet per sec

sulphuret of allyle. The odor OF the
