ADDITIONAL EXPERIMENTS YESTERDAY,
Urder the supervision OF the surHeors,
Professors Bell and Taintor this morning
mRde another application 10 the patients
body Of the Balance, with view Of com.
plstirE the testS OF Saturday, which were
not entirely conclusive, and MCsrtRining
definitely and certainly, II possible, the
exact location Of the hall. Professors Bell
aud Taintur have teen almost constantly
engaged Tor two weeks on experiments
W In the lnduCtion Balance, and
have made several notifications and
Improvements which greatly add
to Its efficiency. They used
this improved apparatus upon the Presi.
dents body for the hrSt time Saturday,
and although II indicated family the loca.
ton OF the ball, 1t WAR aiterward found to
be slightly out OF adjustment and the ex.
pertinent was not regarded as conclusive.
The result OF this mornings tests, how.
ever, are entirely satisfactory, both to
Professors Bell and Taintor and 10 the at.
tending surgeons, and 1t is now unani.
nlously agreed that the location OF the
ball has been ascertained with reasonable
exactness and certainty, and that II lies as
heretofore stated in the dispatches, in the
front wall Of the abdomen, Immediately
over the groin, about five inches below
aud to the right oil the naval.
The experiments this morning wero re.

however, when the small disks attached

cate the location OF the black and blue
spot which appeared on the lower right

whether the experlmenter could see
the disk or not. Whenever they
we're placed In that particular
position, he became instsntly aware ot the
TACT and announced it.. The experiments
were varied and continued until all we're
con uyinCed that the bullet had boen found,
or at least loCa ed 10 aRttaight line run.

iusI above tue groin on the right side.
| II was not possible TO learn With any de.
gree OF certainty the depth which the ball
lies imbedded on this imaginary line, but
"A the front wall ol the abdomen at this
point Ia about two aud half inches 10
thickness, the ball must be within that
distance OF the surface. The resulta
fully con6tm the original dlFRoncstS ol

and that fact is 40 gratifying to them as d
complete tuccesa OF The induction balance
h to Professors Bell and TAinlor. This ID
tbe tjtst instance in which an iinbsddsd
bullet has been accurately and definitely
located without probing, and by purely
scientific methods. There Is no Intention
on the part ol the surgeons 10 perform an
operation ior the removal Of the ball al
present, and 90 long as 1t gives NO trouble
II will be allowed 10 remain in its present
