packages Of arsenic which received aud portions
OF which delivered to another expert for
analysis might have become mixed. But
the Professor brought to the witness stand the

minds for future arguments that the packages might
have been tampered with. although it could not be
proven that they were. The principal witness OF

of adjournment he had not reached the real
point of his testimony, but gave sort or
lecture which of great scientinc interest.
Hayden was brought into the court room some
minutes before tho hour of opening and sat in his
usual place for u moment gazing around absently.

den preserves a cool demeanor, and pencils nu-
mcrous memoranda in a little red book. His sug-
gestons to his counsel arc frequent, and are often
acted upon in the cross-eXaminaion of the States
witnesses. The court room was thronged through
out the day. and many of Yale's professors and
other gentlemen interested in scientific matters
present.
PROFESSOR JOHNSON ON THE STAND.
Professor Johnson's cross-examination was re-
sumed ON the opening of the court. He was closely
Intercepted to the possibility Of error in hand
ling the several packages of arsenic placed in his
hands by the State. portions of which were trans
ferred to other experts for. analysis. He admitted
opening the packages at various times, but scored
good point by stating that it his rule to open
only package at time and then close it before
touching another By adopting this simple rule
there no risk OF intermingling their contents.
On each package pencilled the date Of receipt.

marks as hieroglyphics, Professor Johnson with
amused smile, rejoined quickly, "Oh, no; I'm not q
professor of the black art"
Mr.. Watrous (intcrrupting)-Never mind. Profess

After so...2 at great length his testimony in
chief as to the q.actites taken from the packages
for analysis, the witness was ask Now, Pro-
fessor, want you to that you never took any
arsenic from those packages excepting as you have
stated"
Professor Johnson-Never, sir. 1 took none out
excepting to weigh and return the contents to the
wrappers or to deliver samples, Us described. for
analysis.
Tho defence thought that they had secured point
in finding presumed error in the addition on one
of the wrappers of quantities contained therein.
The inference would be- OF course. that If the wit
made mistake the probabilities that
he had made others. and all would so to show
possibility that the packages might have been tam
percd with without discovery by him. The alleged
error in the addition was of ten grains only and
moment LATER when the State took the witness again,
he was requested to so over the addition.
Mr.. WaIrous-Will you put those figures down
again?
Professor Johnson-Ycs; but may say that am
rather poor at figures.
The new addition showed that the original addi-
ton had really been correct. Witness next produced
the little tin spice box containing the arseuc found
in Hayden's barn. and after stating that the pur-
ported ounce therein was not exactly ounce said
that correct ounces Of arsenic seldom sold by
druggists; they do the weighing quickly to get
the poison out OF the way, aud as 1T is cheap stuff
no great IL exercised.
Cross-examined-The weight of the alleged ounce
in the tin box 81 410 grains Sheriff Hull
brought Inc the scales from the drug store where
this arsenic is claimed to have been purchased and
found the ounce weight l-lO grains short.
PROFESSOR WHITE cRoss-ExAMINED.
Professor White. of Yale College, recalled, and
identified u package OF arsenic purchased at the
same store by Mr. Colgrove; the wrapper of this
BORE for purposes OF identification. Colgrove's pri
vate mark-"A. B. c." some portions were given to
Professors Johnson and Dana for analysis.
Cross-oxamined-I received the package from Col
grove 10th of October, 1S7S the 18th opened 1t
and placed about the twentieth part OF a grain on
each of two microscopic slides for examination;
the 2lst handed the paper to Professor johnson,
who removed two grains; November 23 filled four

Mr.. watrous-Do you know what that whito pow

Professor white-H you mean by tho absolute

but am confident tnat 1t was arsenic.
SUGAR vs.. ARSENIC
Mr.. Watrous-Do you know that IL was not pulver-
lied sugar!
Professor white-Certanly it was not; the micro.
scope would show the difference of the crystals. And
with some irritation he added, II tell you know IL
was not sugar" tLaughterD
Mr.. watrous-why did you examine Il to see that
IL wasn't like sugar?
Professor whte-I had occasion to for other pur.
poses connected with this case, and my microscope
convinced me- Arsenic crystallizes in the form of
pctahedrons, or forms which have certain mathc-
matical relations To each other. But don't claim

Counsel for the State objected to this line of ex.

not as n expert. but to show what was done with
the Cosrove package of arsenic.
Mr.. Watrous-But the State has always claimed
