Fargo Forum: That an alcohol
made from bleached flour contains a
poison that was strong enough to
kill rabbits. and did kill a number OF
them that were used in series OF
experiments, was the startling testi.
mony that was given by; Prof. E. F.
Ladd in the district court today. On
the other hand, that it was not the
alcohol that killed but was poison
left in the -four by the bleaching pro-
cess was; also proved by the professor
when he made public a series of ex-
periments made with alcohol from, un-
bleached -four. This alcohol taken
from exactly the same amount of
flour as the alcohol taken from the
bleached flour that killed the rabbits;
made in exactly the same way, ad-
ministered to three rabbits and al
though it was administered on three
different days, 1t had no effect on the
rabbits. -
Professor Ladd did not make these
experiments himself, as he did not
want 1t said that he had fixed up
some sort of dope, but he left it to
Professor Smith of the North Dakota
A. C. and DR.. Van Es assisted with
the experiments and made post NOR
tenn examinations on the rabbits that
died. 5.s.5s
The alcohol used was in each in
stance taken from about the same
amount of flour as is used in quar-
ter of loaf Of bread, and on the
stand this morning Professor Ladd
told just how this -four was obtained
and where obtained d-how the alcohol
was made and gave tables showing
the results Of his experiments. He
also made a number of other expert
ments on rabbits from other solutions
from bleached and unbleached flour.
After the professor had showed the
results of these experiments DR.. Van
Es was placed on the stand and gave
his testimony corroborating the tes~
timony of Professor Ladd and giving
the post morten examinations made
on the rabbits. sIl .
Three fours were used In the ex-
periments. One called in the tables
given in this article-over bleached,
was secured from a local flour mill.
It had been bleached at the mill and
was pleached again at; the "A. q. chem
istry until it was considerably over
bleached. The second -four used was
flour bought in the open market
in Fargo. 1t was bleached flour
made in this state. The third flour
used was unbleached flour bought in
the open market. ..5l
