Sometimes they occurred in sleep, and were prolonged with painful
vividness into his waking moments. Sometimes they seemed to grow out of
his intense meditation, or to present themselves before his eyes as the
projection of a powerful inner impression. All his sensations were
abnormally acute, and his ever-active imagination confused the
border-lands of the actual and the visionary. Such a nature as
Shelley's, through its far greater susceptibility than is common even
when with artistic temperaments, was debarred in moments of high-strung
emotion from observing the ordinary distinctions of subject and object;
and this peculiar quality must never be forgotten when we seek to
estimate the proper proportions of Dichtung and Wahreit in certain
episodes of his biography. The strange story, for example, told by
Peacock about a supposed warning he had received in the spring of this
year from Mr. Williams of Tremadoc, may possibly be explained on the
hypothesis that his brooding thoughts had taken form before him, both
ear and eye having been unconsciously pressed into the service of a
subjective energy. (Fraser's Magazine, January, 1860, page 98.)

On their return to England in September, Shelley took a cottage at Great
Marlow on the Thames, in order to be near his friend Peacock. While it
was being prepared for the reception of his family, he stayed at Bath,
and there heard of Harriet's suicide. The life that once was dearest to
him, had ended thus in misery, desertion, want. The mother of his two
children, abandoned by both her husband and her lover, and driven from
her father's home, had drowned herself after a brief struggle with
circumstance. However Shelley may have felt that his conscience was free
from blame, however small an element of self-reproach may have mingled
with his grief and horror, there is no doubt that he suffered most
acutely. His deepest ground for remorse seems to have been the
conviction that he had drawn Harriet into a sphere of thought and
