The emergence of a new term to describe a certain phenomenon, of a new adjective to designate a certain quality, is always of interest, both linguistically and from the point of view of the history of human thought. That history would be a much simpler matter (and language, too, a much more precise instrument) if new thoughts on their appearance, and new facts at their discovery, could at once be analysed and explained and named with scientific precision. But even in science this seldom happens; we find rather that a whole complex group of facts, like those for instance of gas or electricity, are at first somewhat vaguely noticed, and are given, more or less by chance, a name like that of gas, which is an arbitrary formation, or that of electricity, which is derived from the attractive power of electrum or amber when rubbed — the first electric phenomenon to be noticed.
