HAYDEN ON TRIAL
DR.. Treadwell's Lecture Continued
on Blood Corpuscles
A VERITABLE FREE LANCE.
A Discovery Affecting the Motive
OF the Murder.
New HAVEN, Conn. Nov. ls. 1879.

New HAVEN. Conn., Nov. 49, 1879.
The interesting scientific lecture by DR.. Tread
veil of Boston, on blood corpuscies was continued
In the Hayden trial to-day At one time the Doctor
branched of from his subject to give some severe
raps to scientific gentlemen who differed with him
to the method Of examining corpuscles and as to
tho results obtained. Surgeon Woodward. Of the
United States army, was savsgely attacked. on
scientific grounds alone. of course. and the defence
made no effort to check DIR. TreadwelIs onslaught.
It was interesting to the spectators, and.
while it did the State no boneht, 1t
was gain for the defence as an illustration to the
jury of the differing opinions Of scientists on sub
ject which the witness professed to be SO con-
hdent. Generally speaking. Dr. Treadwell was care
full and good Witness but by this attack he added no
value to his testimony and at another time during
the forenoon he made an embarrassing slip In MS
arithmetic. One OF the claims OF the State has been
that HAYDEN was prompted to murder the girl be-
cause she believed she was pregnant by him and he
feared damaging revelations The post-mortem ex-
aminations showed that she was not pregnant. but
Dr. Jewett, New Haven. was called this afternoon
and testified that the girl was afflicted with an
ovarian tumor. This would give rise to symp..
toms closely resembling those of pregnancy.
When DIR. Treadwell recalled for further cross
examination he made q correction Of the measure
ment of the four blood corpuscles obtained from q
spot on Hayden's shirt No. 2. and proceeding to
explain when checked by Mr.. watrous with. Never
mind the words. Doctor. let US have the thought

ARITHMKrIcAL BLUNDER.
Two particular corpuscles of the four-nfnitesi-
NAL atoms. measuring about $4,000 of an inch
were the subject of fifteen minutes controversy be-
tween Mr.. Watrous and the witness. Finally the
latter asked to give the average of the two.
measuring. respectively. 1879 and 1-275S of
inch. He made the addition on his blackboard
rectly. 5So5, but, dividing by two, gave the
answer 1897
"Eh? What's that?" exclaimed Mr. watrous; "my
figures different"
The Doctor. going his figures again. saw his
error and Mr.. watrous did not relieve his ennbar-
rsssment very much by excaiming:-
II just wanted to show to the jury that experts
fallibe, we'll as other people Your other fig
ures may have been wrong, as well as these"
Mr.. Watrous next advanced the ingenious theory
that the minute blood spots the shirt might have
been made by the killing Of mosquitoes which had
sucked human blood, but DR.. Treadwell rejoined
that they presented no such appearance. The blood
found in the groove of HaydeD's pocket knife was
next considered. and the witness said that. while
the blood corpuscles had been preserved from rust
by the dirt gathered in the groove. there

some questioning DR.. Treadwell said that he was
unable to produce the microscopic slides on which
he had mounted the blood specimens, after
animation by the microscope the matter had been
destroyed in submitting them to chemical test
the gualcum test-to determine whether the par
tcles were really blood corpuscles. Two Of these
the accuracy OF this method, proved one by the
other. The doubt is due to the TACT that other sub
stances than blood give by this test results very
nearly similar.

"He may have said they resembled blood. but

"Of course not. But if you give me dried blood

be necessary to treat the blood for some time
to restore the shrunken corpuscles to their normal
condition Even with perfectly fresh blood it would
be necessary for me to send to Boston for special

"But Professor Richardson now agrees with me,

Then occurred one of the most interesting and
spicy events of the trial Being questioned to tho
accuracy of certain statements by Surgeon Wood
ward o: the United States Army, blood corpuscle
measurements, DR.. Treadwell launched out into Q
scathing criticism of DR.. Woodward. his methods
and his deductions. 1t was unusual spectacle OF
witness employed as an expert at large per d EN-
pay seizing the opportunity and occupying time to
pitch into another professional gentleman who
didn't happen to agree with him. Dr. Trcadwcu
said that while Woodward had done good work IN
the preparation of the medical records OF the war;
lie had. by his own admissions, been able give but

BY this time the Doctors attack was becoming in

good with the jury.
"why." said DIR. TreadweI. substantially "wood.
