who had driven a big broad-shouldered man to the Carlson cottage on the
night of the murder, and likewise identified Coughlin as the man he had
seen run up the steps of the slaughter-house and disappear behind the
front door. Kunze rocked to and fro with fury during this testimony, and
glared wickedly at the witness. Coughlin's gaze never left his accuser,
but his face flushed and his deep set eyes blazed.

SURPRISES FOR THE DEFENSE.

From a medical point of view, the testimony of Microscopists Tolman and
Belfield, and Chemist Haines, of the Rush Medical College was
exceedingly interesting. Stains from the floor of the Carlson cottage,
the hair found clinging to the trunk purchased by Simonds, the hair cut
from the head of the murdered man, the single thread of hair discovered
on cake of soap in the kitchen of the cottage, and fresh and dried blood
from the trunk itself, were the articles on which the experts had
experimented. The chemist had been requested to determine whether the
reddish stains were those of blood, while the task of determining the
probable origin of the blood and the relation of one hair to the other
was assigned to the microscopists. The evidence of all three experts was
conclusive. Chemist Haines had subjected the stained chips from the
floor of the cottage to four experiments, three of a chemical nature and
the fourth with a microscope, and the result furnished indubitable proof
that the stains were those of blood, while Microscopist Tolman, by other
tests, was equally well satisfied that the blood had come from a human
body. Additional tests had been made on a strand of hair found on the
cake of soap, and which was lighter in color in some portions than in
others, while Dr. Cronin's hair was brown. The fact that the single
strand appeared light in color to the naked eye seemed to indicate that
it could not have come from Dr. Cronin's head, but it was demonstrated
by the experts that hairs placed on soap or other alkaline substances
became bleached in a manner similar to the color of the single strand.
This evidence was of vital importance as it linked the hair found in the
trunk with the hair cut from Dr. Cronin's head, and went far toward
proving that one of the murderers had washed his hands with the soap
after the diabolical work in the parlor had been done.

A surprise was in store for the defense at this juncture of the trial,
in the form of several witnesses whose identity and testimon
