"--Thus they
Breathing united Force with fixed Thought
Mov'd on _in Silence to soft Pipes_.

Who does not see Porpoises and Dolphins tumbling about in the Ocean
when he reads this Line?

"--On smooth the Seal,
And bended Dolphins play: part huge of Bulk,
Wallowing unwieldy, enormous in their Gate,
Tempest the Ocean.--

How variously the Rivers run in these Verses?

"--So the watry Throng
Wave rowling after Wave, where way they found,
If steep, with Torrent rapture, if through plain
Soft Ebbing.--

How is the Verse extended where the Whale lies at length upon the
Ocean!

"--There Leviathan
Hugest of living Creatures, on the Deep
Stretch'd like a Promontory sleeps.--

How does the Line labour when the Elephant is working himself through
the stiff Clay, whilst the lesser Animals sprout up as it were in an
Instant!
