The Organs ofIespiration Tn ir lie
and Abuse"
Upon taking the stand, Dr. johnson
said his subject covered the whole field of
anatomy, physiology. aud pathology.
Respiration consisted in the exchange az
the gases Fl the blood for the oxygen az
the air. The carbOnlc acid must BE- r..
moved from the blood or We die. 'rher.
j. a process carried ON in the body similar
Ia that Of combustion In the air. As The
wood IN burning takes up oxygen. and
the carbon l. changed into carbOnic acid:
SO lin the human body carbonic acid was
constantly being produced and thrown on
through the lungs. and oxygen a con-
stantly consumed The animal body i in
deed "A furnace. We must be- fed with air
or we perish.
The organs of respiration are those thar
perform this work Of exchanging carbonic
acid for the oxygen Of the air. Naming
them IN order. they are the nose. the
mouth, the larynx. the trachea, and The
tubes and air cells OF the lungs. Bv ref
erencc 10 "A manikin. the speaker explained
the shape and character OF the air pass
ages of the nose. There is "A large extent
OF surface in the nasal cavity, the use Of
which Is 10 warm and moisten the air a.
we draw II into the lungs. so that il will
not irritate them. IL also had the po~er
to collect and retain the little particles Of
dust that otherwise might reach the air
cells and do serious harm. Ii was for
these reasons that il was not healthfgl 10

was grossly abused by not using il as ma
ture Intended. as an organ OF respiration.
The Doctor pointed out on the mauikiu
the nerves of smell. These neryes are not
only productive of great pleasure. but they
often warn OF danger. What j. the mean
ing of "A sneeze. It tells Us we are liable
TO take cold. The upper air passages are
exceedingly sensitive. and irritation 10
these causes great pam, whereas but little
pain Is experienced when the vital MEM
branes below are diseased. The delicate
membranes OF the throat nav be injured
by the use Of tobacco and alcohol. and seri-
Gus pulmonary disorders may result.
The larynx performs the double furc-
ton OF an organ of respiration and of
speech. Ii is a delicate two-strinse~I mu-
steal instrument. which, ia speaking or
singing. we play upon as The musician
does upon his harp. lie explained the
expansion n contraction Of the cords
by which the various notes were produced.
Children. he said, were liable 10 have these
cords strained by oycr-usc when young.
especially where they were severely drilled
in the high notes. Open-air speakers also
were liable TO injurc or even lose their
voices.
lie then explained. by reference 10 a
east and two skeletons. the anato-
my of the lungs and then position with
reference to other organs. and showed how
the muscular action OF the diaphragm aids
respiration.
He referred to the difference in shape
between the male and female chest. This
difference was not owing entirely to dress,
was natural. lie advocated freedom
Of dress. The chest should neither be-
below nor above 10y drawing
the shoulders forward. He did not be-
lieve in drawing the shoulders back forci-
bly, by means of shoulder-braces: the de-
should rather bc corrected by volun-
effort.
We never breathe with absolute regu-
larity. IL We watch ourselves we will md
that about every sixth breath will be-
than the Others. When we exhale
never expel all the air from the lungs.
When we get tired and sleepy AT the close
the day We do nsr keep up 30 steadily
the muscular action Of breathing. and We
up the lack of air in the lungs by a
yawn. Unpleasant a. gaping may be- in
company. il helps 10 wake Us up.
The blood is made up Of a liquid on
float little globules l-3OOOof an inch
diameter. There are about C5.c00, CO.
20 OF these in a mans blood. Each one
back TO the heart freighted with
,arbonic acid. and is pumped 10 the lungs
70 discharge it, little load. and takeanother
IF oxygen and carry il to The farthest part
the body. The process goes on from
ife's dawn To it, close. He could not see
any one could study this wonderful
mechanism OF the human heart and not
eel that there is One whose thoughts are
than ours.
The speaker was frequently applauded
Turing the course of his lecture. which
vas the first Of a course To be- given weekly

andrews delivers the next. His subject
will be: Decomposition As a Cause Of
Disease"
