REV. HAYDENS TRIAL
Surgeon Woodward, Of the United States
Army, as a Blood Expert.
UNMEASURABLE C0RPUSCLES
How He Demolished DR.. Tread
ass wells Theories.


United States Army. spent the forenoon in an ex-
tended and detailed statement of the progress that
has been made in this delicate science. and the
various possibilities impossibiities of identify
ing The bloods of man ana the lower animals
by microscopical measurements of 0he
OF their respective corpusces. DR.. Treadwel
o. Boston. scientist in this branch. and who has
testified for the State that he had identified blood
stains Hayden's knife and clothing human
blood. by measuring their corpuscles present
during the day. His pencil jotted notes of hundreds
of Surgeon Woodward's statements. to be met when
he had his turn upon the witness stand. 1t was
noticeable that DIR. Woodward addressed himself to
his scientific rival in the most telling points of
his lecture. and in few instances where
1t was admitted that DIR. Treadwells pro-
cesses good his face lighted with smile Of ap
proval. However. q WHOLE the tenor of DR.. Wood
wards statements was that. for very many reasons.
the Identification by size could not be absolutely
correct because OF the impractcabity Of obtaining
absolutely correct measurements OF objects in the
field Of microscope. Some confusion was occa-
stoned by the different systems u measurement
used by the two men. DR.. Woodward giving results
in decmals of an inch and DR.. Treadwell in common
fractions. As the latter had been noted in the
lawyers note books comparisons could not be
made without wearying computations. The jury
bore the infiction Of all this science
with resignation; but the majority OF them. while
making pretence Of attention. preferred to stare
out Of the windows at the falling snowfakes, to
study the faces of New Haven bellies among the spoc
tators The seats allotted to visitors we'll filed
this morning, but thinned out under the scientific
deluge only to fill up again at the afternoon session.
Surgeon Woodward held the stand until the
hour Of adjournment
