TIE HUMAN BRAIN.
DIR. KrOhn's Entertaining Lecture Before
the Institute.

DIR. krohn's Entertaining Lecture Before
the Institute.
When DR.. Krohn came TO Rock ISL
and last Monday morning to take
part in the institute, he expected to
meet a great many brainy people.
Feeling that his own brain was like
ly to give way in case OF any I'M
looked for emergency, he brought
with him in his grip and extra cere-
brum and cerebellum. This extra
brain played a prominent part in the
lecture last night. 1t was that of a
woman, and was endowed with sew
eral rather peculiar characteristics.
The doctor was neatly introduced
by Supt. Marshall, and held the close
attention of 4 very Intelligent audi
ence for over an hour, in spite of the
great discomfort caused by the heat.
No notes were used, but the speak
er frequently brought into play sew
eral charts showing the different di-
visions OF the store house of intelli-
gence.
Among other things he stated that
the brain used to be considered only
as the source of a lubricant for the
eyes. The idea that the size of the
brain is indicative OF intelligence is
erroneous. The convolutions are
the true induces of the intellectual
ability. The left side of the brain
controls the muscles of the right side
of the body, and as consequence
the left part of the cerebrum is
found to be larger and better devel-
oped than the other in all persons
who are right handed. Another mis-
conception that human beings have
entertained for many years, is that a
high forehead is sure sign of con-
siderable mental activity. The lee
turer alluded to a man who had both
of the front lobes of the brain re-
moved without lcssening in the least
any of the regular acts of the intel
lect. The only noticeable effect was
the patients inability to use profane
language. An interesting compari-
son of journalists brain was made
with that of mathematician. In the
former the convolutions are found
much more numerous, while the lat
ter is characterised by much deeper
assures. The mathematician had
done the deeper thinking. but only
on few subjects. The editors men,
tai power had been eXcrted in many
different directions, and he hadn't
had time to study each subject mi
nutely.
At the close the address the audi
ence was permitted to make close
inspection of the organ itself, and
many were the con lectures and re-
marks that were made in honor of
the woman who had once used the
brain.
Institute Proceedings.
There were lot of tardy teachers
yesterday at the roll call, but they
will all tell their pupils this fall that
punctuality is one of the principal
virtues.
The early morning promised pleas
ant temperature. but by o'clock the
fond illusion had been dispelled. No
one found an opportunity to shiver
with cold. and perspiration was
plenty. The hot weather, however.
did not prevent Prof. Mccormick
from conducting an unusually inter-
esting exercise in history. The at
tack on Baltimore, and the destruc-
ton of the national capitol in 1914
was the topic the teachers talked
about. Stories and anecdotes innu-
merable concerning the vandalism of
the British admiral. Cockburn. and
the retreat of President Madison and
his cabinet, made the half hour pass
quickly. DIR. Mccormick is uni
versal favorite; everybody likes him.
He has taking magnetic manner
that makes it easy for him to gain
and hold the sympathy and attention
OF any who are favored with an OPP
portunity of listening to him.
DIR. krohn gave at 9:35 a graphic
account of the origin, over 20 years
ago in Germany, of an association of
teachers who commenced in sys-
tematic manner to find out the ac-
tual status of the child's mind at the
age he enters school. Investigations
showed a wonderful state of igno-
rance concerning the simplest objects
of nature that surround most chill
dren. For instance only Is per cent
of the city children and As per cent
of country children had ever seen the
sun rise. G. Stanley Hall found
about the same conditions existing in
the cities of this country at the time
his investigation began in Boston
several years ago.
The doctor stated that there are
good many wrong methods of teach
ing with objects, and gave an anus
