ARSENIC ON TRIAL.
Professor Dana's Third Day
in the Hayden Case.
NOTHING ABOUT THE MURDER
Roundabout Method of Discovering Mary
Stannard's Assassin.
New HAVEN. Conn.,. Oct. "a. ls7

New HAVEN. Conn.,. Oct "a. 1870.
The second week OF the Hayden trial terminated
to-day. Tho character of the evidence for five
days past naturally leads to query whether this is
a murder trial q series of scientific lectures The
energies OF counsel both sides have been bent to
the eucidaton. for the benefit of the jury. of the
processes of manufacturing arsenic. and of the
forms its particles present under microscopical
animation. Crystallography. mineralogy and the
technical many-syllabled words employed in
those sciences have been dnned into the
Of court and jury and spectators
until everybody has become heartily tired of them.
After all this the jurymen to familiar phrase.

of them have manifested for day or
more past every appearance of being bored.
while sat this afternoon with closed eyes
and look of Christian resignation upon their
faces. However. the scientific testimony which has
been given to the nature, manufacture and
properties of arsenic is of much importance to
the State. IN this Hayden the evidence
is largely circumstsntial. No eye witnessed tho
tragedy. Tho testimony that Hayden was seen near
the spot on the evcntful afternoon is by no means
strong. BY chain of evidence regarding the
arsenic found in Mary Stannard's stomach tho State
prove that the arsenic which Hayden bought on the
day of the murder is the arsenic found in her
stomach 1t may be able to fix fact that Hayden
was the man who with her at the hour when
she met her death, and give foundation to the as
sumption that it was his hand that used the
knife and the Jagged stone. This is what the
State is reaching after, and not mere object OF
proving that Hayden poisoned the girl. For this
Professor Dana pursued in Europe. at the expense OF
the State investigations into the processes Of arsenic
manufacture. For this he prepared of mi
croscopic slides bearing arsenlcal atoms and dia-
grams showing differences in these atoms. And
after this he has at least been enabled to that

respondent to-day that scientists affirm that the ex-
pert testimony in this trial regarding arsenic will DO
81 very great Importance TO the country. For one
thing. 1t will tend to expe arsenic, and the whole
class OF mineral poisons from the list Of poisons
used by criminals and thereby narrow the list as a
whole. sIet II be known that arsenic and other
poisons of crystalline nature may DO identified per-
f.cty under tho microscope and criminals will avoid
them. Professor Theodore j. Wormley, of the Uni
versity OF Pennsylvania who was present to-day,

FURTHER ARsESfcAL EXPERIMENTS.
Professor Dana, rcsuming. testified that of the
"Colgrove," 'barn." Mckee" and stomach"
arsenics he had received and examined sufficiently
large quantity 10 make that examination thorough
one with reference 10 the samples involved. Janu-
AIRY ~ nd 30 1872 received samples of arsenic from
Professor Johnson. The former was barn" arsenic
and my microscope showed IL to possess the
distinguishing characteristics those OF January
~. which were also barn" arsenic. From the simi-
larty believe that my examination of the twenty
microscopic slides prepared therefron has given me
= correct knowledge Of the arsenic which was in the
tin box found in Hayden's barn. Also in January
received sample OF the Mckee arsenic from Mr.
Mckee's drug storel. OF which mounted eight
samples taken from different parts OF the surface of
the powder exposed. These enabled 20 fx the
distinctive character of the Mckee" arsenic. The
Importance OF this particular arsenic 10 that the
State claims that the Mckee" arsenic Is identical
with that bought from ler's drug by Hayden
Tyler having bought tho original lot from McKee,
from Professor White two lots of tho "colgrove'
arsenic, aud In September. 1879, a third lot from
Professor White. have found the same distinguish
ing characters ia all OF these three samples"

IL cannot conceive that IL will from my knowledge
