(Catalectic:)

Dosn't thou 'ear my 'erse's legs, as they canters awaay?
Proputty, proputty, proputty—that's what I 'ears 'em saay.
Proputty, proputty, proputty—Sam, thou's an ass for thy paains:
Theer's moor sense i' one o' 'is legs nor in all thy braains.

(Tennyson: Northern Farmer—new style. ab. 1860.)

Thee I behold as a bird borne in with the wind from the west,
Straight from the sunset, across white waves whence rose as a daughter
Venus thy mother, in years when the world was a water at rest.

(Swinburne: Hesperia.)

Seven-stress iambic.

There's not a joy the world can give like that it takes away
When the glow of early thought declines in feeling's dull decay;
'Tis not on youth's smooth cheek the blush alone, which fades so fast,
But the tender bloom of heart is gone, ere youth itself be past.

(Byron: Stanzas for Music. 1815.)

Here we have anacrusis in lines 2 and 4.
