Carboneum Hydrogenisatum

This gas, which was experimented with by Sir Humphrey Davy, produces a

condition almost resembling an apoplectic attack. Stupefaction: comatose; surface cold and

• ▸completely insensible.
• ▸Spasm as in lock-jaw.
• ▸Arms flexed at elbows.
• ▸One mental symptom is

peculiar: an extraordinary sensation of contentment, so that life seems exalted; all his thoughts

appear in a moment as if seen in an inner mirror. Many eye symptoms were noted: steady and

• ▸extreme oscillation of the eyeballs.
• ▸Eyes distorted.
• ▸Lids half closed.
• ▸Dark bodies moving before

eyes. > By open air (vertigo, convulsions). It is a popular custom to take children suffering from

whooping-cough to breathe the air at a gas-works. A case has been recorded in which an

accidental escape of gas in a child's bedroom affected a prompt cure of its whooping-cough.

Illuminating gas is a complex gas, carburetted hydrogen being the leading ingredient. In the

Schema are included some symptoms produced by illuminating coal gas.

extremely weak.

Every 10 to 15 minutes tingling, prickly sensation, passed all over body, esp. the

numb, tingling sensation, until 2 p.m., when he went into spasms.
