Gheney,s lecture, and that at DR.. Hansen S
lecture Durrant was not present General
DICKINSON, Mr.. Barnes said, had asked
general questions regarding the actions OF
Durrant on the afternoon of April 3, and
ne, therefore, thought the way clear for
HallS evidence. The objection was sus-
tanned, however, and Hall was called from
the stand.
Or. julius Rosenstirn came forward as
the next, and, as it proved the last wit
ness OF the day. He said he had practiced
medlclne and surgery for twenty years in
THIS city and Tor number of years in Ger
many. He claimed to be qualified to an
swer questions on the symptoms of gas in
halatlon, and so once more the hypotheti
cal question prepared by the prosecution
was repeated. In answer the witness said:
AFTER breathing for three four or five min
uteS com Dlnatlon OF air and gas, where car
oonic oxide formed from 10 to IS per cent, the
probabilities that the person would become
unconscious, or at least Intoxicated, and would
show symptoms of the inhalation of gas"
What are the outward symptoms"
IA person would go through three stages
He would feel burning pain in the face and
mead, pulsating in the temples and arteries
the lace would be full of blood. the mucous
membranes will become deeper red and he
would see things before his eyes That repre-
sents the stages from consciousness to uncon-
sclousness. He may have sensations of a pleas
ant or unpleasant kind and then unconscious
ness.'
"What are the marked symptoms?"
"A marked flushing of the face and a tinge
OF rednesS to the visible mucous membranes''
How long does that continue?"
II is liable to continue quite time; say an
hour or two hours"
Can you explain the causes of the redness
or fushing?"
The blood becomes cherry red by the COM
p1nat1on OF the monoxide of carbon with the
colorlng material in the blood"
Us this your actual experienced"
- nave seen In my practice, two cases of the
n msbg Stage se OF gas P0sGning but have seen
IN those two cases were the symptoms as
you have statedf"
"And they were similar to those described in
medical works?"
Eyes, sir
There was flushing or redness of the face?"
Eyes"
General Dickinson then commenced to
cross-examine.
docs not nausea follow in many cases of gas
poisoning"
Eyes, sir"
IN what proportion must the air and gas be
That depends upon the individual, but I
should think that in three minutes in an
atmosphere containing fifteen parts of carbonic
OXIDE, one should be affected in a marked
degree"
Give us some idea of the percentage the
rabbits?' w.
dogs and rabbits are easily killed; fifteen or
twenty per cent would be certain to render
them unconscious in from four to five
minutes"
"In human beings is the susceptibility
greater or less?"
Ordinarily they are about as susceptible as
these animals"
What are the symptoms OF the first stage9"
Dlzzlness, nausea, flushing, temporal arteries
pulsating"
Suppose person in this first stage passed
lnto an atmosphere free from gas, would he
recover immediately"
THE result of the intoxication would
gradually go away, as the carbonic oxide would
be gradually eliminated from the blood"
would consumer"
"After such condition it would take at
least an hour"
Glow long could a man work over a sun
burner such as has been described and under
such circumstances"
"He might operate there five minutes, but
that ought to bring him to the first stage''
might he regulate his breathing so as to
allow himself to work longer?"
mo, he must breathe certain amount"
us 1t not possi BILE TO regulate and reduce the
number OF breaths?'
Eyes, but the same amount must be in
haled''
What would become of the gas in the sun
burner described to your"
ut would be diffused into the air."
Glow soon would it do this?"
at would take some little time"
Then Peixotto asked if the upward
tendency of gas escaping under pressure
would not make it ascend before diffusing,
and the doctor said it would.
This ended the examination of DR..
Rosenstirn, and Barnes announced that
he had but one witness more ANYWAY
and he was doubtful as to whether or not
