- n. A colorless, inflammable, poisonous gas, C2N2, with a peach-blossom odor, so called from its tendency to form blue compounds; obtained by heating ammonium oxalate, mercuric cyanide, etc. It is obtained in combination, forming an alkaline cyanide when nitrogen or a nitrogenous compound is strongly ignited with carbon and soda or potash. It conducts itself like a member of the halogen group of elements, and shows a tendency to form complex compounds. The name is also applied to the univalent radical, CN (the half molecule of cyanogen proper), which was one of the first compound radicals recognized.
from The Century Dictionary and Cyclopedia
- n. Chemical symbol Cy. A compound radical, CN, composed of one atom of nitrogen and one of carbon.

A second commentator suggested it might have been a piece of a comet; comets often contain cyanogen, which at low levels could cause the symptoms described.
Last month, its instruments showed that the comet was emitting a toxic gas called cyanogen whose output increased fivefold over an eight-day period before slowly decreasing again.
In 1910, many people panicked when astronomers revealed Earth would pass through the cyanogen-rich tail of Comet Halley.
Jets spewing from the comet's nucleus contain cyanogen (CN: a poisonous gas found in many comets) and diatomic carbon (C2).
False alarm: The wispy tail of the comet couldn't penetrate Earth's dense atmosphere; even it if had penetrated, there wasn't enough cyanogen to cause real trouble.
I think we can get the formula out of him for curing this cyanogen damage.
Supposedly the cancer cells would gobble it up, free the cyanogen portion of the molecule and be poisoned.
"Heat it -- to ninety, or a hundred degrees -- it gives off a deadly gas -- cyanogen."
Leaching is another important process for cyanogen reduction during cassava processing.
But the tail's mostly ammonia, methane, carbon dioxide, water vapour, cyanogen - '
