| you have made--:s 1t your opinion
| that alum In these various compounds,
in Baking Powders such as ysu have
examined, is Injurious?
A. 1t ia my opinion, based upon &C
tual experiments on living animals.
CHARLES F. CHANDLER, called on
behalf OF the plaintiff, being duly
sworn, testified as folio We: = 7

city of New York?
A. do.

@. Your are and have bee n professor
of chemistry in several colleges? :?
| A. have.
q. Please state how long that EN-.
ploymept of yourself has beeu, and
with what colleges you are now con-
| nected? ... ..
A. I am at present professor of
| chemistry in the academic department
of Columbia college; the School of
Mines, Columbia college; the New

Surgeons, and the New York
College of Pharmacy.
Q. You are president. also Of the
board of health, ale you not?
A. I am.
@. In your vaious employments,
have you had frequent occasion to ex-
anime the question Of the wholesome
ness of food. and the beneficial or in-
furious effects of it's Ingredients
A. I have.
@. Twill ask you in regard to the
use of alum with soda, in a baking
powder, whether or not it is neutral
iZad-is there any Injurious constitu-
ent Of alum left?
A. There ia an injurious constituent
left after the mixture of alum and
bicabonste Of soda.
q. Without using anv nicely of
chemical terms, what is your opinion
about the use of alum in a baking
powder, in combination with bicar-
Donate soda and other ingredients, for
raising bread-whether Injurious or
not?
A. [ think 1t is dangerous 10 the
digestive organs, and liable to produce
serious disturbance of the liver of the
individual making use Of such DOW
ders. ~.
Henry Morton, president of "Stevens
Institute" called in behalf of the
plaintiff, being duly sworn, testified
as follows:
@. You are president of Stevens
Institute?
A. am.
@. And have for many years been a
chemist?
A. have.
Q. Have you had occasion 10 ex-
anime the substances which are used
in the position of Baking Pow.
ders?
A. I have.
@. Did you, some time ago, exams
inc sample Of Dooley's Baking Pow
der?
A. did.
Q. Is that 1t, sir (handing CAM?
A. Yes, sir; that is it.
Q. Well. what kind of alum did it
contain?
A. 1t contained potash alum.
@. Did you make any eX' rsct Of that
alum, to show the kind?
A. I did; 1 extracted large quanti.
ty of it as potash alum. and iL ia in
that bottle which I have now here
(showing boltle); that is potash alum
which came out of the alum Bakina
Powder that was in that can.
Plaintiffs counsel offers said can of
Dooley's Baking Powder in evi.
dence.
Q. Now, cir, have you made any
experiment in the bread made from
Baking Powder. to see whether there
was any soluble alumina In the pread
itself?
A. I have; I took a portion of this
powder and mixed it with flour in the
directed proportions, and baked a
small loaf with 1t; then I soaked this
ioaf-the interior part OF it-in cold
water, and made an extract, in which
I readily detected. by the usual tests.
aum-that is alumina in q soluble
condition. ....
@. Does any Baking Powder In
~hich any alumina salts enter, con-
tain alumina, ia your opinion, which
can be absolbe in the process of di-
gestion-are not such Objectionable?
A. Very decidedly Objectionable, in
my opinion.
Q. Why do ycu eay-from what
sy tenn of reasoning do you make it
ont-that because alum is injurious,
| alumiLa is Injurious?
A. Because the injurious effects of
alumina, when it gets into the 81 lomach
and reacts on the organs, are the same;
this hydrate of alumina meets in the
stomach the gastric juices, and reacts
| with them the same as alum would: it
forms, in fact, kind of alum in the
stomach with those aside, and what
ever alum would do, it would do.
| Dr.. Samuel w. johnson, professor OF
chemistry, in the scientific school,
| Yale College, being duly sworn, tes-
| titled as follows:
@. You have had much to do in the
examination Of substances that enter
INTO food, and the adulteration OF
food?
| A. More or lees; yes, sir.
| Q. After the use of alum with soda.
in a baking powder, in your opinion.
is there any Injurious substance left J?
A. In my opinion, there is an iDiuri.
GUS substance left.
| Q. What, sir, two years ago, was the
prevailing opinion among scientific
men az to the effect of the use of alum
in Baking Powders?
A. AS far as py acquaintance with
scientific men is concerned, my per-
sonal opinion is derived from nv in,
vestigation aud from reading; Ishould
think the opinion was that alum. OF
any compound of alumina, would be
decidedly injurious.
@. Do understand you to say thai
any Baking Powder in which there
are alumincus salts, or any resultant
from alum which could be absorbed in
