Block Quote and Centered

In addition to Body Text, there are paragraph tags named Block Quote and Center. Here is a Block Quote paragraph.

Why, there, there, there, there! A diamond gone, cost me two thousand ducats in Frankfort! The curse never fell upon our nation till now; I never felt it till now. Two thousand ducats in that, and other precious, precious jewels. I would my daughter were dead at my foot, and the jewels in her ear! Would she were hearsed at my foot, and the jewels in her coffin! No news of them? Why, thou loss upon loss! The thief gone with so much, and so much to find the thief, and no satisfaction, no revenge! Nor no ill luck stirring but what lights o' my shedding.

Here is a centered paragraph:

Nay, that's true, that's very true. Go, Tubal, fee me an officer; bespeak him a fortnight before. I will have the heart of him if he forfeit, for were he out of Venice I can make what merchandise I will. Go, Tubal, and meet me at our synagogue; go, good Tubal; at our synagogue, Tubal.
