Miss X. can trace many of her visions to memories,
as Maury could in his illusions hypnagogiques. Thus, Miss X. saw in
the crystal, the printed announcement of a friend's death. She had
not consciously read the Times, but remembered that she had held it
up before her face as a firescreen. This kind of revival, as she
says, corresponds to the writing, with planchette, of scraps from
the Chanson de Roland, by a person who had never _consciously_ read
a line of it, and who did not even know what stratum of Old French
was represented by the fragments. Miss X. seems not to know either;
for she calls it 'Provencal'. Similar instances of memory revived
are not very uncommon in dreams. Miss X. can consciously put a
group of fanciful characters into the crystal, while this is beyond
the power of the seer known to the writer, who has attempted to
perceive what a friend is doing at a distance, but with no success.
Thus she tried to discover what the writer might be about, and
secured a view of two large sunny rooms, with a shadowy figure
therein. Now it is very probable that the writer was in just such a
room, at --- Castle, but the seer saw, on the library table, a
singular mirror, which did not exist there, and a model of a castle,
also non-existent. The knowledge that the person sought for was
staying at a 'castle,' may have unconsciously suggested this model
in the picture.

A pretty case of revived memory is given by Miss X. She wanted the
date of Ptolemy Philadelphus. Later, in the crystal, she saw a
conventional old Jew, writing in a book with massive clasps. Using
a magnifying glass, she found that he was writing Greek, but the
lines faded, and she only saw the Roman numerals LXX. These
suggested the seventy Hebrews who wrote the Septuagint, with the
date, 277 B.C., which served for Ptolemy Philadelphus. Miss X.
later remembered a memoria technica which she had once learned, with
the clue, 'Now Jewish elders indite a Greek copy'. It is obvious
that these queer symbolical reawakenings of memory explain much of
the (apparently) 'unknown' information given by 'ghosts,' and in
dreams. A lady, who had long been in very bad health, was one
evening seized by a violent recrudescence of memory, and for hours
poured out the minutest details of the most trivial occurrences; the
attack was followed by a cerebral malady from which she fortunately
recovered. The same phenomenon of awakened memory has occasionally
been
