ITS NON-REMOVAL.
The attending physicians, replying
to comments upon the fact that they
did not attempt to remove the bullet
on the day of the shooting. say that
the President was quite too weak to
withstand the shock of the operation !;
that his condition was not such rs to
warrant the use of anTSthetlcS, and
that the shock incident to the op-
Grafton would have been practically
equivalent to another wound. DIR.
Hamilton quite agrees with the attend
ing surgeons that the conditions were
not such as to warrant heroic treat
ment. If the present opinion rs to the
location of the ball is correct, that it Is
in the right lilac fossa, there undouht-
eddy will he an attempt To extract it.,

LITTLE DANGER OF BLOOD POISONING

can he seen, to be realized. This Is no
doubt legitimate source of anxiety,
but happily this serious danger, 81 far
IT'S can be Judged from symptoms, is
absent. The healing process continues
without interruption, and the PreSi-
dent bears up bravely under the strain

PROF. BELLS WONDERFUL MACHINE.
The apparatus in its present improv-
ed form consists of two Hat coils about
four inches in diameter and one-half
an inch thickness of insulated copper
wire, ii battery, Il condenser, an inter
rupter OF circuit breaker. and IA tcle-
phone. The ends of the primary or
inducing coil are connected with the
poles of the battery and in the same
tili ll' 4 anu NllltNli III
terruptcr, whose vibrating tongue
opens and closes the circuit with great
rapidity. The end of the secondary
coil, i'll which the current is to he in
Quoted, are carried to the binding
posts of Bell telephone. When the
connections have all thus been made
the secondary coil is laid on the prima-
ry or inducing coil, 50 that their re
spcctive circumfcrcnccs exactly coin
eide The circuit breakers is then set
in motion, and the rapidly interrupted
current through the primary coil in
duccS another current of higher intcn-
Sity in the secondary coil, and as it
does 50 loud musical tone is heard in
the telephone with which the sccon-
diary coil is connected. As long rs the
current is maintained and the circum-
ferCnccS of the two coils are kept in
exact coincidence the musical note in
the telephone does not change its pitch
or intensity. If, however, the expert
memtcr slides the upper coil along an
inch or 50 upon the lower, so that their
circumference no longer correspond,
the intensity of the musical tone is di-
minishcd, and just in proportion as the
centres of the flat coils are separated
by greater or less distance the intcn-
sity of the musical tone is lcsScncd or
increased. When the upper coil has
been slidden over the lower so that
they simply overlap the centre of the
one corresponding nearly with point
on the circumference of the other. the
tone in the telephone ceases.
Ii the upper coil is pushed IL little fur
thcr to one side, so that it ovcrlaps
still less, the tone is again heard.
BY delicate manipulation it is posi-
bic To adjust the centres of the over
tapping coils at such Il distance one
from the other that Il perfect balance is
brought about, and when this is the
case the telephone makes no sound
whatever. The centres of the overlap
ping coils cannot then he moved either
toward or away from one another with
out causing the telephone to break its
silence. When the coils are thus bal
anccd, and the telephone is mute. it is
found that what may bc called the area
of coincidence, or, in other words, the
area of the overlapping parts of the
two fiat coils has become highly scnsi-
tive to the approach of metal and man
ifestS its scnsitiVcness by low note in
the telephone. As long as metal is
kept away from this area the telephone
remains silent. but if piece of lead,
for instance, is brought within dis
lance of four OF five inches from the
overlapping parts of the coils there
may be heard i'll the telephone faint
but audibly pcrccptible note, which he
comes louder and louder rs the metal
approaches the sensitive surface, and
throws the coils more and more out of
balance. 1t will readily he seen that.

the small area bounded by the inter
Secting circumference of the overlap
ping coils can he placed exactly above
Il bullet or other piece of metal imbed-
led in the body. provided the metal
does not lie at too great depth. As
soon as the balanced coils begin tn feel
the disturbance caused by their ap-
proach to the imbedded bullet. the tel
rphOne announces the fact by faint,
musical note. and this note
grows louder and louder until the over
tapping parts of the coils are directly
above the disturbing metal, when the
sound reaches its maximum.
