[Footnote a: An etymology of this kind would have been particularly interesting in the hands of so learned and acute a man as Mr. Wedgwood. It would have afforded him a capital example of the fact that considerable differences in the form and sound of words meaning the same thing prove nothing against the onomatopoeic theory, but merely that the same sound represents a different thing to different ears. L. Boare, mugire, E. moo; F. beugler, E. bellow; G. leuen, L. lugere, E. low, are all attempts at the same sound, or, which would not affect the question, variations of an original radical go or gu. For a full discussion of the matter, admirable for its thorough learning, see Pictet, Les Origines Indo-Europeennes, Vol. I. Section 86.]
In the case of crag, Mr. Wedgwood argues from a sound whose frequency and marked character (and colds must have been frequent when the fig-tree was the only draper) gave a name to the organ producing it. We can easily imagine it. One of these early pagans comes home of an evening, heated from the chase, and squats himself on the damp clay floor of a country-seat imperfectly guarded against draughts. The next morning he says to his helpmeet, “Mrs. Barbar, I have a dreadful cold in my—hrac! hrac!” Here he is interrupted by a violent fit of coughing, and resorts to semeiology by pointing to his throat. Similar incidents carrying apprehension (as Lord Macaulay would say) to the breezy interiors of a thousand shanties on the same fatal morning, the domestic circle would know no name so expressive as hrac for that fatal tube through which man, ingenious in illegitimate perversion, daily compels the innocent breath to discharge a plumbeous hail of rhetoric.
