of 0.722 to 0.720, and its
vapour is very inflammable.

_Symptoms._--When taken as a liquid, same as alcohol. When inhaled as
vapour, causes slow, prolonged, and stertorous breathing; face becomes
pale, lips bluish, surface of body cold. Pulse first quickens, then
slows. Pupils dilated, eyes glassy and fixed, muscles become flabby and
relaxed, profound anaesthesia. Then pulse sinks and coma ensues,
sensation being entirely suspended. Nausea and vomiting not uncommon.

_Post-Mortem Appearances._--Brain and lungs congested. Cavities of heart
full of dark, liquid blood. Vessels at upper part of spinal cord
congested.

_Treatment._--Exposure to pure air, cold affusion, artificial
respiration, galvanism.

_Method of Extraction from the Contents of the Stomach._--Same as for
alcohol. During distillation pass some of the vapour into concentrated
solution of bichromate of potash, nitric and sulphuric acids, and note
reaction as for alcohol.

_Tests._--Vapour burns with smoky flame, depositing carbon. Sparingly
soluble in water. With bichromate of potash and sulphuric acid same as
alcohol.

=Chloroform.=--A colourless liquid, specific gravity 1.490 to 1.495,
very volatile, giving off dense vapour. Sweet taste and pleasant odour.

_Symptoms._--When swallowed, characteristic smell in breath, anxious
countenance, burning pain in the throat, stomach, and region of the
abdomen, staggering gait, coldness of the extremities, vomiting,
insensibility, deepening into coma, with stertorous breathing, dilated
pupils, and imperceptible pulse. When inhaled, much the same as ether,
but produces insensibility and muscular relaxation more rapidly. It
would be impossible to instantly render a person insensible by holding a
pocket-handkerchief saturated with chloroform over the face. Statements
such as this, which are often made in cases of robbery from the person
and in cases of rape, are incredible.

_Delayed Chloroform-Poisoning._--Death may take place in from four to
seven days after chloroform has been administered, especially in the
case of children. The internal organs are found to be fattily
degenerated, and death is thought to be due to acetonuria.

_Post-Mortem Appearances._--Cerebral and pulmonary congestion. Heart
empty, or right side distended with dark blood.

_Treatment._--Stomach-tube and free lavage; cold affusion; drawing
forward tongue; artificial respiration; galvanism and suspension with
head downward. Inhalation
