At the end of Chapter 1, there are actually 3 quotes. The Shakespeare references are as follows:

1) "Trifles light as air, Are to the jealous, confirmation strong, "As proofs of Holy Writ"

"Othello", Act 3, Scene 3, Line 322

2) "The poor beetle, which we tread upon, "In corporal sufferance feels a pang as great "As when a giant dies"

"Measure For Measure", Act 1, Scene 3, Line 81

3) "Like Patience on a monument "Smiling at Grief"

"Twelfth Night", Act 4, Scene 2, Line 107

It helps to have a "Shakeapeare's Concord" handy, so you can look up the lines quickly. A great reference guide.

You cannot know how much I was curious about that animalist sentence of Shakespeare's!! I don't know "Measure for Measure"... I'll look for it at the bookshop.

Thx again!
