will recognize in it an excellent illustration to the following passage:—

“I’ the world’s volume

Our Britain seems as of it, but not in ’t;

In a great pool, a swan’s nest.”

Cymbeline, Act iii. Sc. 4.

For the purpose of comparison, Shakespeare has found the swan very useful in metaphor.

Benvolio, referring to Rosaline, says,—

“Compare her face with some that I shall show,

And I will make thee think thy swan a crow.”

Romeo and Juliet, Act i. Sc. 2.
