Shelley's "Prometheus Unbound."—Can any of your correspondents, by conjecture or reference to the original MS., elucidate the meaning of the following passage, which occurs in Act II. Sc. 4. of this extraordinary poem? It sounds so sweetly that one cannot but wish it were possible to understand it.

"Asia. Who made that sense which, when the winds of spring

In rarest visitation, or the voice

Of one beloved heard in youth alone,

Fills the faint eyes with falling tears which dim

The radiant looks of unbewailing flowers,

And leaves this peopled world a solitude

When it returns no more?"
