Article Discusses Action o
Thyroxin on Paramecium
EXPERIMENT IS UNUSUAL
Gland Products Produce
Diverse Effects
In the March number of the Jour
nal of General Physiology is a pa
per from the laboratory of Experi
mental Biology of the University o:
Oregon medical school in Portland
by Harry Beal Torrey, Matthew C
Biddle and Jessie L. Brodie, en
titled “Thyroxin as a depressanl
of the division rate of Paramec
ium. ”
Thyroxin is a crystalline sub
stance that was obtained a few
years ago by E. C. Kendall of th(
Mayo Foundation from the thyrioc
gland and is held by Kendall to be
the essential principle of that gland
This view is supported by the
fact that when taken into the
body in appropriate doses thyrox
in produces the same clinical ef
fects that total thyroid produces
Animals Affected Differently
From some observations of the
function of the thyroid, however, il
appeared that the thyroid gland
when fed to animals produces con
trary effects not easily understood,
It seemed possible that these con
trary effects might be produced by
different substances in the gland
thyroxin being one of them. With
this in view experiments were be
gun four years ago, the progress of
which have been reported year by
year to scientific societies, which
were reported in full for the firs!
time in the Journal of General
Physiology.
When thyroxin is introduced intc
the body of an animal, its effect
on the tissues cannot be directly
obtained. When one-celled micro
organisms are used, however, the
effects of thyroxin can be obtained
directly upon the single living coll
Thq common organism Paramecium
was selected for the purpose and il
was found, contrary to expectation
that while total thyroid very dis
tinctly accelerated the growth and
reproduction of Paramecium, thy
roxin distinctly depressed them
The acceleration is now readily ex
plained by the fact that the bac
teria which serve ns food for Para
meeium grow very abundantly in s
thyroid medium, and that anything
which will increase the food sup
ply of Paramecium in this connec
tion will accelerate its reproductive
processes. It was noeessnry to de
termine whether the depressant ef
feet, of thyroxin on the Paramec
ium was due to a depressant effect
upon the growth of food bacteria
This question has now been answer
ed in the negative. Thyroxin acts
directly on Paramecium. It is now
known from this and other re
search that there are several sub
stances obtainable from the thyroid
gland that have diverse effects up
on living cells, so that it is not
entirely clear that thyroxin is, af
ter all, more than one of the pro
ducts of the thyroid gland that of
fect the growth activities of the
body tissues.
Thyroxin Kept on Slides
' In conducting this investigation
on thyroxin Paramecin were kept
in small drops of culture medium
on small glass microscope slides at
a constant temperature and at a
constant degree of acidity. Changes
in temperature and in acidity both
effect the growth of Paramecium.
The acidity was checked by a meth
od developed at Johns Hopkins
f since this investigation was begun,
which made possible the determina
tion of the acidity of very small
drops. By checking the acidity, the
culture medium was not only made
, more tolerant to Paramecium, but
more nutritious as well.

of Louis XI.
Sabers Support Drapes
The drapes of the pavilion and
booths will fall In soft folds, and
will be held up by sabres, copied
after those used in tourneys. The
costumes for the orchestra were de
signed by Jane BoDine.
The fleur-de-lis, the royal emb
lem of France, is the motif carried
out in the drapes over the stage.
The drapes will be held up by
lances, similar to those used by
French knights. Pages will stand
at each side of the Gothic arches
of the recess. *
The walls of the Armory will be
completely covered with slender
folds of material resembling toile
pientre, tapestry cloth which was
used in all chauteaus of that time.
The design was made by Constance
Cleaver. '
Orests Form Motif
Huge crests, exact representations
of the crest of the Duke of Bur
gundy, will form the central motif
of the hangings. The crest con
tains a lion rampant on a field of
orange. Quatre feuilles, carrying
out the same color scheme,' will be
used around the base of the walls,
the pavilion and stage. Orange
flood lights will be used to heighten
the color of the orange hangings,
and blue-green lights will likewise
be used to bring out the color of
the bluish hangings. The ceiling
will represent a stone ceiling, arid
it will be so arranged as to give the
effect of height and spaciousness.
In addition to the flood lights used
for the canoe fete, two additional
ones will be used.
The cover design of the programs,
drawn by Arthur Gale, chairman of
the prom, contains a picture of a
knight at arms holding a lance
from which a pennant, bearing the
inscription “Junior Prom,” is flut
tering. The knight is standing at
the entrance to the main hall of a
feudal chauteau.
The patrons and patronesses for
the Prom are as follows: President
and Mrs. P. L. Campbell, Governor
Pierce, Mr. and Mrs. Georgo T.
Gerlinger, Mr. and Mrs. Henry D.

LOST ARTICLES WAIT
AT UNIVERSITY DEPOT
All students who have lost any
thing during the entire school year
are urged to inquire for it at the
lost and found department of the
University depot before the end of
this term.
Even if you have inquired be
fore, go again. Articles often come
in just after they have been called
for, and then stay in the depot
! for weeks, as the owner things,
“Well, I asked once and it wasn’t
there.”
The usual number of umbrellas,
gold pencils, pens, coats and caps
are still at the depot, and there
are only three weeks left this year
for the owners to claim them.
If you don’t want your lost arti
cles held over until next fall for
the auction sale, be sure ta pay the
University depot a visit before
June 15, and ask about them.
PROMINENT EDUCATOR
TO SPEAK HERE IN JUNE
David Snedden, Sociologist
And Author, Plans Visit
David Snedden, at present pro
fessor in educational sociology at
the teachers’ college at Columbia
university, will be the most out
standing and important visitor to
the campus this summer. He is
scheduled to speak here June 29 and
30.
Mr. Snedden has had experience
in educational and sociological lines
and is considered one of the lead
ing educators in the country. He
is the author of a great number of
books, some of which have been
written in collaboration with other
professors.
Among his books are “Adminis
tration of Education for Juvenile
Delinquents,” and “School Eeports
and School Efficiency,” written by
Snedden and Allen.
Mr. Snedden has held important
positions on the faculty of Columbia
and Stanford universities, and be
sides this has been interested and
engaged in work in secondary
schools over the country.
He is a man of outspoken con
victions, a vigorous and dynamic
sort of worker. Perhaps for this
reason he is considered and sought
as a great speaker. He has been
engaged as instructor in educational
sociology at University of Wash
ington this summer.
The topics of his talks have not
as yet been decided upon, but it
is expected that they will be of
general interest. He has announced
that he will speak as often as de
sired and it is possible that he may
speak other times than at two daily
assemblies.

work, the judges said.
| The members of the faculty who
served as judges were: Miss Maude

department; Dean Walker, director
of the loan fund and student ad

Latin department.
All Space Taken
One of the largest crowds which
ever attended a canoe fete here
witnessed the event last night. Be
cause the bleachers in previous
years have been too small to
accommodate the crowds, addi
tional ones were constructed
this year, as well as the erection
of temporary bleachers in the street
just back of the regular bleachers.
Every ticket for the reserved seat
section had been sold before last
evening, and every seat in the
general admission section was
filled.

night:
