ARSENIC GRINDING.
Witnesses for the Defence who Expert

DIR AwING IT FINE.


In the Hayden trial to-day the forenoon was occu-
pied with the medical expert testimony by Dr. San
ford professor of anatomy in the Yale College med-
cal department. Generally speaking. his evidence
on delicate points was less positive than that given
by other experts produced by the derence. and the
State secured some admissions OF value. Of them
tending to indorse the findings of the States 8
expert. DIR. Treadwen, In the matter of blood
stains on Hayden's clothing and knife. His man
ner. however, indicated indisposition. through
kindness as much az anything else. to oppose Dr.
Treadwell's conclusions The States claim OF
arsenic Identification by the character and size of
crystals pretty successfully attacked this after
noon by the testimony OF practical miller con-
versant with the grinding of chemicals. who showed
reasons why uniformity is practically impossible
An extended and brilliant crossexamination failed

THESIS BLOOD coRPuscLEs.
Professor Sanford testified that he discovered no
blood stains on the articles of Hayden's clothing
submitted to him, and admitted that he had given
attention to the science of blood corpusces In the
detection Of human blood. Proceeding into de-
scription OF the present era of this science. he
id:-The corpuscles Of can readily be distin-
guished from those of animals. whose blood cor
puscles have different forms; also human corpuscles
can be distinguished from those Of animals
having the form, but widely differing
in their size; think it is impossible
to discriminate between human corpuscles
and others of the form. closely corresponding
in size. to distinguish between human corpusces
and those of many OF the lower animals; of these
there several whose oorpuscles not discrim-
mated from those of human blood by the most
acting microscopists: by this mean that those pre-
tending to make very nice distinctions will not say
whether q certain specimen is human blood or that

opossum. porcupine. and perhaps the dog.
Mr.. Waller. interrupting-Dr. Treadwell. the
States expert stated all these II you name any
others than what he gave us wish you would.
DR.. Sanford continuing Perhaps the walrus
and the guinea pig; it is impossible for to dis
tinguish between human blood corpuscles and those
OF two or three domestic animals whose corpuscles
closely approach in size. For instance. human
corpusces and those of the blood of the dog pig and
cannot distinguish apart. except under the most
favorable circumstances that the specimen fresh,
the blood healthy and that have sufficient quantity
should want hundreds Of them-a small drop of
blood-because they vary much among them
selves.
Mr.. watrous-Can you name the degrees of varia-
ton?
DR.. Sanford:-It is greater in the lower animals;
not over eighty per cent will be Of uniform size.
while in man it is ninety per cent; the ranges Of
measurement for mans are between 1e,6OOth of an
inch and 1-4.0O0th: the dogs wi1 range from
1-3. .OO0th to 1450Oth. yet have corpuscles in
dogs blood quite as large as the average OF mans.
WHY THEY VARY.
Continuing he gave the measurements of
puscles of other animals substantially as given by
Dr. Tresdwel for the State last month. Dr. Sanford,
however, advanced theory that the size OF the
puscles varied according to the density OF the

the animals you have mentioned? A. Not unless the

stains merely the corpuscles could not be distin-
guished apart
Q. Do you regard Phofer. OF Chicago. an

that he preends to distinguish even the sex OF the
animal by the corpuscles.

The matter Of the ovarian tumor taken up,
and DR.. Sanford corroborated the statements OF
other experts for the defence that small tumor,
situated the upper portion OF the ovary where 1t
would interfere with the functions of adjacent
organs. could not give rise to any symptoms OF
pregnancy or even feeling of uneasiness. On the
question OF the fow OF blood from the wound in
Mary Stannard's throat he said that such wound

corpse found there must have been considerable
spattering, unless, indeed the heart of the victim
was not acting with its usual energy. The arsenic
taken and the blow on the head would limit the
flow Of blood by abatinR the hearts action.
blood had flowed from the wound, would you
not be Of the impression that part of the blood
had been drained off somewhere else? A. More
blood must have escaped than is accounted for; at
least double the quantity.
