n, but especially at its changes. One German
authority--Burdach--goes the comical length of asserting that the
propensity of somnambulists to walk on the roofs of houses is owing to
the attraction of the moon, and that they have a peculiar pleasure in
contemplating the moon, even in the day time. Whatever may be the cause
of the affection, somnambulism undoubtedly assumes different degrees of
intensity. The first degree evinces itself by the movements we have
referred to and by sleep-talking. This stage is said to be marked by an
impossibility of opening the eyes, which are as if glued together. There
are many curious circumstances to be observed concerning sleep-talking.
The intonation of the voice differs from the waking state, and persons
for the most part express themselves with unusual facility.
We were acquainted with a young lady accustomed to sit up in bed and
recite poetry in her sleep, whose mother assured us that she sometimes
took cognizance of circumstances which she could not, in any way,
account for. On one occasion they had been to a ball; and, after the
daughter was in bed and asleep, her mother went quietly into her room,
and taking away her dress and gloves deposited them in another room.
Presently, as usual, the fair somnambule began talking in her sleep; her
mother entered, as usual, into conversation with her; and, at length,
asked, "But what have you done with your new ball-dress?" "Why, you
know," replied she, "you have laid it on the couch in the drawing-room."
"Yes," continued the mother, "but your gloves--what have you done with
them?" "You know well enough," she answered, in an angry tone, "you have
locked them up in your jewel-box." Both answers were correct; and it may
be here observed that somnambulists, if equivocated with in
conversation, or in any way played upon, will express themselves
annoyed, and betray angry feelings. The truthfulness of sleep-talking
may, we apprehend, always be relied on. In this state there is no
attempt at evasion; no ingenuity exercised to disguise any thing. The
master-mind of Shakspeare--which seems to have divined the secrets of
Nature, and illustrated scientific principles before they were
discovered by philosophers--recognized this fact, in making Iago thus
rouse the jealousy of Othello:
"There are a kind of men so loose of soul
That in their sleep will mutter their affairs;
One of this kind is Cassio.
In sleep
