The meaning of the word Gabion, as it is used in the poem, is not to be sought for in any dictionary. It was of the venerable old gentleman Mr Ruthven′s own coining, and it was well enough understood among his select friends, to mean nothing else but the miscellaneous curiosities in his closet humorously described in the poem.
