The Savannah morning news. (Savannah, Ga.) 1900-current, 1901-04-10

One OF the young women connected
with Hull House, Chicago, was recently
showing a collection of photographs OF
classical pictures to street urchn, and
when she came to a copy of the "Sistine
Madonna" she asked. DO you know
what that representa-" yes" said the
boy. that is Jesus and His mother" Did
you notice. continued the teacher, how
beautiful their faces are? You cannot
ind such beauty of expression in any 9TH
er picture" But it's the rims around
their heads, ma'am. that gives them
away interrupted the boy
The automobile is shortly to make its
entrance into the Sahara, says LIE Congo
Beige" The arrival of two machines, be-
| longing respectively to Baron Joseph
| Pierre and Baron Crawhez, and driven by
their owners, made great sensation re-
| Gently at Laghouat. The travellers left
Dfelfa at l O'clock. In spite of the de-
plorable condition of the road they arriv-
ed at Laghouat in about eight hours
The natives whom they passed on the
! route appeared both surprised and fright
ened and ran away, shouting, ''They are
the DEVILS machinesp
Nearly 100000 square miles, or about
30 per cent. of the total area of the
United States, have been mapped by the
United States Geological Survey during
the past twenty years Several states
have now been carefully mapped on
scale of one mile to the inch and their
elevations and surface relief expressed by
contour lines located at five to twenty
feet vertically In addition to the annual
appropriation for the Geological Survey
of $3.50, 900, several of the states pass ed-
ditional appropriations to hurry the work.
Pennsylvania, for instance, annually APP
propriates $4,000 for this purpose. The ex-
pense of mapping naturally depends upon
the character of the country. The cost
of mapping open country is from 50
to $40 square mile, and that of forest
or mountainous areas double or triple
that amount. The government publishes
the results of these surveys in uniform
atlas size, 1872 inches by 20 inches, which
can be procured by the general public
at a nominal cost
"A new method of distinguishing hui
man blood from that of enimaIs has been
discovered independently by DR.. Uhlen-
Luth of Greifswald and Drs. Wassermann
and Schutze of Berlin. 1t appears that
il is now possible to obtain a definite re-
action from blood-stans, however old,
which indicates with approximate certain
ty the source of the blood under exam
ination. This result is based on the fact
have been injected with the blood of an
animal of a different species, when added
to a dilution of blood from the latter,
produces therein a well-marked precipi-
tate. Thus, if rabbit be injected with
human blood, the serum of the rabbit
blood when added to a dilution of hu-
man blood, causes immediate turbidity,
phenomenon which is conspicuously alb
sent when it is added to any other kind
of blood. The only element of uncer-
tainty is that the blood of monkeys re-
acts, to some extent, like human blood.
This is, of course, comparatively unim-
portant from medico-legal point of view,
and the two varieties are distinguishable
anyhow, for there is notable difference
between the time required for a dilution
of monkeys blood 40 become cloudy and
the time required for a dilution of mans.
The method, therefore, should be of i'm
portant practical application in medico-
legal practice
Sound is one of the simplest things in
the world, and yet to many persons,
young and old. it is one of the most mys-
FERROUS. Tell them, for example, that the
fall of tree in a forest makes no sound
in itself, and they smile incredulously; or,
If they believe you, they confess that
they cannot understand it. When you say
that the presence of some person or some
thing with ears is absolutely essential to
the production of sound they seem unable
to grasp the idea, and contend that the
fall of the tree does make, and cannot
help making a noise, which is there, all
the same, whether there be anybody to
hear it or not But they are wrong, of
course for there is no sound except in
the ear. In the making of a sound there
are three essential conditions. Let us
take this illustration of the tree in the
forest 1t falls and strikes the ground.
That is the first condition. Its striking
the ground sets the air around it into vio-
lent agitation. That is the second condi-
ton; but there is no sound yet, only
series of vibrations through the air
spreading out in every direction from the
fallen tree. These vibrations, it must be
remembered, are not sound. They are
only the factors that produce it, and they
cannot produce it until the third condi-
tion is supplied, which is the tympanum,
or drum, of somebody's ear against
which they strike. and thus makes a
sound Sound, therefore, is nothing but
the striking of air vibrations against the
drum of the ear; it exists only in the
ear, and cannot exist out of it. The
conditions that produce it exist out of
the ear, but the ear is absolutely neces-
sary to complete it.
"A paper just published by Sir Lauder
Brunton and DIR. Zunnicliffe upon Ger
tain apparently injurious constituents Of
potable spirits goes a long way towards
explaining the reason for the various
physiological symptoms arising from over
indulgence in alcoholic liquors, particular
ly whiskey. Their researches show that
while intoxication is undoubtedly caused
by the ethyl alcohol in the liquor, the
actual way in which inebriates get drunk,
or get sober after being drunk depends on
the quality of the liquor partaken of, and
that this quality is positively determined
by the amount of an organic impurity
called "furfural' which the whisky con-
tains. The source of furfural in the man
ufacture of whskey is class of sub
stances known as pentosans; these are
derived from the cellulose of the grain
husks, and under the influence of heat,
in the presence of acids, are in the wash
still converted into furfural. This fur
fural in the body tends to pass into its
corresponding acid thus diminishing the
alkaiinity of the blood, which, according
to most physicians. favors the occurrence
of equity deposits in the joints. The phys
illogical action of pure furfural on ami
mails and man was studied and led to in
teresting results. II gives rise, il APP
pears to paralysis of the voluntary mus
cles, and to clonic and tonic commissions.
The odd point, however, about these
symptoms is their transient nature; i'm
