The testimony given today at the mur-
Court, No l, developed that the defendant
is laboring under form of insanity en-
tirely different from that attribut, ed to him
by numerous witnesses during the pro-
ceedngs. The new form is termed ''pora-
noia,'' as stated by DIR. Rose, the first
witness offered by the defence. judging
from what he had learned concerning the
circumstances concerning the defendant.
DIR. Irving c. .Rosse. a physician of thirty
nine years practice was the first witness
called by the defence this morning. DR.

timony given in the case yesterday, and
read the accounts of the killing of Jane

would be natural for the other member
of the same family to be of unbalanced
minds.
From the circumstances connected with
the case, as developed by the testimony,
DIR. Rose classified the form OF insanity
under which the defendant is laboring as
'poranoia.'
In reply TO a hypothetical question. by
the defence, covering all the salient points

ness said, if the assumptions be true, a
person laboring under such conditions of
mind, would be mentally unbalanced.
On cross examination Dr. Rosse said that
il the circumstances as incorporated in the
hypothetical question of the defence were
not proven to be true. he would not con-
cede that the person whose characteristics
they purported to represent was suffering
from ''poranoia. Insane persons he said
do not generally act from design. He
knew DIR. Chaplin. who testified on behalf
