put new cOrKS III. nlarkeu OHS uot-
tie so could remember it.
l put my bottles into satchel which
l carried strapped across my shoulders.
DR.. Barr and Col. Summers were the
only ones who knew / had the bottles.
| got on the train, sat in one corner
with the organ in the bucket and seal
ed in the jars Watched it all night.
Next morning locked it up in my pri-
vate closet, Didn't begin analysis for
more than week.
l put seals on the jars when | had
to come back to Abingdon, no one in
terrupted them. | took due care in
beginning my analysis, bought new
dinner plate to perform on. I'm
clamped the jars, cut of. a piece of
liver, put it in a test tube, put that in
some water, put in some ten drops of
muratic acid and some copper, then
boilded the mixture. Immediately
the copper became coated over with a
shiney black. This is called Bein-
chefs test. The black indicated arse
mic. That didn't unequivically prove
arsenic. Carried the test further, and
identified this black shiney substance
as arsenic. To make plain, put a drop
of water in with these crystals, then
put in ammoniate of silver. If arsenic'
it should make a bright yellow color.
1t did. then concluded it was un-
mistakably arsenic.
Tried another test. Took little frag-
ment Of the liver, put it in some water
and muriatic acid, boiled it. If arsenic,
it would show in the fluid boiled.
Then put sulphurated hydrogen in
the fluid. If arsenic, it should have
had a yellow colored display, not pure
yellow, Of course. l found it plainly
yellow, Ii arsenic, this yellow
ought to dissolve in ammonia. l
tried it it dissolved. To get it back
put into it some muriatic acid which
destroyed the ammonia, and down
came the yellow stuff again.
Put this in another test, and its ar
senical properties were confirmed. 1t
responded to all the tests satisfactorily.
/ came to the irresistible conclusion
that it was arsenic and came from the
liver. / made third test. Weighed
off two ounces Of the liver, put it in
saucer of water with lamp underit, and
heated it thus for three days. Took
the dried fragments, put in flask with
two teaspoonsful Of muriatic acid. |
distilled this until utterly dry, then
collected the deposit. If any
arsenic, it would be there.
| collected about a tablespoon full OF
stuff, which had aromatic odor, some
thing had never found before.
/ then strained the fluid, added a
little water, and reserved portion for
further test / found in these two
ounces OF liver, about one thirteenth
of grain of arsenic. Didn't get it as
white arsenic, but the same yellow
precipitate. This, however, was
equivalent to one thirteenth grain ol
arsenic. / then made another test,
known as Marsh's test. Took a por
ton OF distilled fluid which had re
served put it into a bottle Of oil of Wit
riol, warter and zinc. This pro
duced hydrogen gas. Put tube
in and applied II light. Hello
piece OF chinaware in tht
flame If any arsenic would have
made black spots on the china ware
l poured in the diluted fluid supposed
to contain arsenic, according to forme
tests. / found little spots on the china
ware. (Here the witness presented thu
china with the spots on it. The jury
examined it.) To show that they wer
Marsh spots Of arsenic, put on then
sulphide of ammonia. This did no
dissolve them away. 1t behaved a
arsenic. / then heated lid to get rid Q
sulphide OF ammonia. 1t left yellow
spot, which / concluded was arsenic
put on that nitric acid ofnitric silver
If arsenic it should turn red. 1t die
Gentlemen, it is conclusive to m
mind that there was arsenic in tin
liver. | know that the stomach is S
closely allied to the liver that it wa
obliged to have arsenic in it, | di
not carry out the test so fully on tn
other organs Would have foun
other poisnns had there been an,
Made first class test; but found II
strychnine. l. is hopeless to identif
strychnine after twenty-one months
J it is p ssib'e, however, that | woul
, have found strychnine. Tested, BIT
did not spread the stomach out on
plate.
