MEDICAL JURISPRUDENCE

' Special' Symptoms.—In addition to the general symptoms of corrosive
poisoning, the following symptoms are observed : —

The tongue is swollen, and is covered with a white coating, resembling
"soaked parchment, which subsequently becomes darker or brown in colour.
It may become a corroded and shapeless mass, if the acid is highly concen-
trated. The tgeth are of a chalky-white colour, and are deprived of their
polish. The lips are usually swollen and excoriated, and brown or even
black streaks resulting from the action of the acid flowing from the mouth
may be found extending from its angles to the sides of the chin and some-
times to the front of the neck. Occasionally salivation has been observed
on the second or third day. In rare cases delay has been caused in the
appearance of the symptoms.

Sulphate of indigo pro-
duces almost the identical
symptoms except that the
mouth, vomited matter and
urine are coloured blue.

Fatal Dose.—The danger-
ous effects of sulphuric acid
depend more upon its
degree of concentration
than upon the absolute
quantity taken. It is quite
possible for a few drops of
concentrated sulphuric acid
to produce death from suffo-
cation by directly coming
into contact with the glottis
resulting in oedema. Half a\
tea-spoonful of concentrated I
sulphuric acid administered
by mistake for castor oil
caused the death of a child,
one year old. The smallest
fatal dose for an adult is
one drachm, though re-
covery has followed four
ounces of the strong acid.
An ounce of sulphate of
indigo killed a young
woman in about eleven
hours.
