And double aqua-fortis, of course,
And double soda-water, perforce,
Are the strongest that ever bubbled!

There's double beauty whenever a Swan
Swims on a Lake, with her double thereon;
And ask the gardener, Luke or John,
Of the beauty of double-blowing—
A double dahlia delights the eye;
And it's far the loveliest sight in the sky
