logical department now occupies the
second and third floors of the south
wing of this building. On the second
| floor are five rooms, including a lee
ture hail. class laboratory. two re-
search laboratories. and a preparation
room. On the third floor is a labora-
tory for advanced students, dark
rooms for Photographic and optical
work, and rooms for apparatus AMI
| equipment.
Well Equipped Laboratories.
A lecture room for the exclusive
use Of the physiological department
is equipped with devices which ex-
perience has SHOWN are helpful to the
teacher in imparting. and tc the stud
ent in grasping, a knowledge of phys
/, iology. The preparation room, in IL
4 rect communication with the lecture
room, is equipped W, Il the apparatus
necessary for the preparation of ma
terial to be used in lecture demon
! STATIONS. Laboratory desks have
also been provided in this room for
advanced students. and undergradu-
| ates, graduates and physicians who
wish to carry on research work. in
the large laboratory is apps satus fol-
the study Of human physiology and
physiological chez istry, Here pre-
medical students a quire knowledge
of experimental ply lology as applied
| to man.
! Study Nerves and Blood Vessels.
One of the tables in the physio-
logical laboratory is provided with
apparatus for the study of the effects
Of the electric current on nerves and
muscles. After the student has de-
termined with this apparatus the en-
act reaction to the electric current OF
the nerves and muscles of animals,
he proceeds to demonstrate similar
! reaction upon his own muscles and
: nerves. The student here learns dow
| TO locate paraiyzed muscles in man.
and the basis fer the treatment CT
such muscles with electricity. On
, the adjoining table is the instrument
with which it is possible to determine
the blood pressure in the human
arteries and the force OF the pulse.
The student is taught the use OF
this instrument and the Interpretation
Of the results obtained with it so
that he will appreciate the value CT
blood pressure estimatlons In the di.
agnosis OF diseases of the heart and
blood vessels.
The study of the eye and defects
1 of vision are provided for at another
/ table A box-like instrument consti-
tuting an artificial eye is so cln-
structed as to permit the student to
| see with 1t Just what of the externai
/ world is seen by the human eye. Not
! only does he study with It the action
of the perfect eye, but he can N
vert it into a defective eye. making it
short sighted long sighted, astig-
matte, etc. After producing these
defects of the artificial eye he learns
/ how to correct the abnormal vision
| by means OF eyeglasses.
Pure and Polluted Air.
An experimental study of air, its
| composition and pollution, is pro-
yided for by other laboratory appa-
ratus. BY means of several lnstru-
ments the student can determine The
composition of atmospheric air and
of exhaled air He can determine &C
curately with 1t just how much oxy-
gen and earbonic acid gas the normal
air contains before 1t Is inhaled, and
how much of these gases this same
air contains when 1t is exhaled from
| the lungs. In this way he learns
from his own experiments that some
Of the oxygen inhaled is not recover
ed, and that in its place the exha, al
air contains carbonic acid gas. This
/ apparatus makes possible de1i0n-
stration of the well-knowr fact that
the oxygen which is !nnaled and does
not reappear is actually carried away
from the lungs by the blood to the
various organs OF the body where it
is used to support the slow eombus-
ton which keeps the body warm;
and that it is In this same combus-
ton that the carbonic acid is formed
which Is taken by the blood to tie
/ lungs, where 1t is exhaled.
Anaiyze Human Body
During the second semester the
large laboratory is U I'd for the study
of physiological chemistry by the ex-
| perimental method Here the pre-
medical student studies the chemical
composition of the human body. BY
means of chemical processes he iso-
lates from the various organs and
fluids of the body many of the sub
stances of which they are composed
Particular study is made OF the COM
| position of the blood and Of the va.
r.ous secretions. so that he may more
! readily discover those changes I'm
their composition produced by dis
ease. The chemical changes which
food undergoes as 1t is digested in
the mouth stomach, and intestines,
forms the subject of another inn
portant division Of the course. The
student thus learns Just how food is
digested, and what the conditions arc
