SKULL DEVELOPMENT.
HOW TO "SlzE UP" YOUR FRIENDS
INTELLECTUAL POWERS.

]
Recently the scientists both in Europe
and America have been giving good
deal Of attention to the conformation and
measurement OF the human head or era
niometry, as they call it.
The studies of DIR. Frederick Peterson.
the insanity expert and specialist in nerv-
ous diseases, Of New York, have been
equally extensive. Their conclusions have
been reached by accurate measurements
and not by feeling bumps, DR.. Peterson
said to me;
THE FRONTAL LoBEs
"In men noted for great attainments
and intellectual capacity all the diane
ters and arcs Of the skull are far above
the normal averages. In other words.
their heads are larger. In many criminals
the diameters and arcs are below the nor
NAL average, and there is also great alb
normslity in shape, especially in heredi-
tary criminals. One side of the head may
be larger than the other, the forehead
may retreat, or there may be some other
lack OF symmetry and proportion. Often
the teeth, jaws and ears are deformed.
| All the higher mental faculties are loca-
ted in the frontal lobes of the brain, and
these naturally have direct proportion
to the length and breadth of the fore.
head. just back of this region are the
muscular centers and the centers for cuta-
neous sensation.
Directly behind the ears and n little
above are the centers for remembering
that which IL heard, and here are I'M
doubtedly located some of the muscular
faculties, for instance, the wonderful
memory Of musical. compositions, such
ss was Possessed by Blind Tom" The
memory of everything seen is stored
away in the posterior lobes OF the brain;
therefore people of great perccptive
power aud who remember well all their
perceptions will be found to have a large
development on the back of the head.
1t has been noted that in people born
blind this part OF the head is smaller
than it should be- In contradistinction
to quack phrenology the perceptive
power is located here in place of Calls
philoprogenitiveness and bump of anna
tiveness, Gall located the perceptive
power immediately over the eve, behind
which ia cavity in the bone containing
no brain.
The average circumference of an
adult mans skull is 20t inches and of
an adult womans 19a inches The aver
age length Of the arc from-the roof of
the nose over the top Of the head to the
most prominent point on the back of the
head Is in man l2t inches and In the wo-

from one ear to the other over the high
est part of the head is in man 12s
inches and in woman 12f The aver

from the middle of tho forehead in
straight line to the hindniost part of, the
head is in a man Z inches and in wo.
man 90. The average diameter through
the widest part of mans head, from
side to side in a straight line, is 81 inches,
and OF wOman's head 81 inches. These
are only few of tho more important
measurements taken,
81 never made less than seventeen
measurements and three drawings of
each head, But in the most careful
studies sometimes from 30 TO 1870 sepa-
rate arcs and diameters are measured.
II will be seen that the head of "a woman
Is ON an average smaller than that of a
man, just as her brain weighs several
ounces less, While il may bc taken as a
| general rule that head of large dimen-
sions is associated with unusual capa-
city in some one or other direction, it is,
Of course, not always the case. One can

ton from tho bonds of intellect; and one
can readily conceive of mucn of their

PACKING OF THE BRAIN
'The skull bones may be twice as
thick as usual, or there may be an un-
! usual amount of fluid in the cavities of
the brain and its coverings Again, a
person with a rather small head may
have more thinking centers to the cubic
inch of brain than the otheri less fat, less
water, less packing of every kind, as in
| the case Of Gambetta, whose brain was
rather small. The word packing is an
excellent one to use in this connection,
| for it describes the condition perfectly
just as delicate china or glass vessels are
packed away in sawdust, hay, etc, for
shipping, SO the fragile cells containing
memories and thoughts are packed away
in an enormous quantity of substance
known as connective TISSUE, which diff
| fers relatively little from hay and saw
dust in structure as seen under the mi
croscope, and which serves an equally
efficient purpose. Hence an idiot is oc.
casionally, though indeed rarely, seen
with an unusually large head; but in the
packing Of his Uranium valuable struct
ures were left out by the thoughtless
workmen, and only the hay and sawdust
slowed away.
"Up 90 the age Of % the development
Of a mans skull depends on his edlca-
ton, and, in fact, his entire environment.
subsequently the mind may develop a
great deal but the skull will not. From
! the age Of 90 the skull retains the same
! proportion and the same dimensions, and
II Is on this account that certain measure
| ments Of the head become useful as a
means Of Identification Of adults They
may change their appearance in many
respects. but cannot voluntarily alter the
shapes Of their heads. NJ Bertillon has
Incorporated therefore, certain skull d.
ameters in his system OF Identification Of
criminals, now much employed In
France, bnt IA yet little in this country"
