Chylesium, identified by Artemus Gordon as a "chemical", bears the "-ium" ending that is typical of metallic elements, according to conventions adopted in the early 19th century. There are exceptions (helium, platinum, tantalum, etc.) but most of the metals with names not ending in "-ium" inherited their nomenclature from alchemy or ancient times. No element with the properties Gordon described were known to exist, then or now.
