Clinical Trials

'Tis a lesson you should heed,
Try, try, try again.
If at first you don't succeed,
Try, try, try again.

But noble souls, through dust and heat,
Rise from disaster and defeat
The stronger.

Pray, pray, thou who also weepest,—
And the drops will slacken so;
Weep, weep—and the watch thou keepest,
With a quicker count will go.
Think,—the shadow on the dial
For the nature most undone,
Marks the passing of the trial,
Proves the presence of the sun.
