te of febrile and inflammatory
disorders--frequently accompanying inflammation of the brain--a
concomitant also of highly excited nervous irritability--equally
connected with hypochondria--and finally united in some cases with gout,
and in others with the effects of excitation produced by several gases.
In all these cases there seems to be a morbid degree of sensibility,
with which this symptom is ready to ally itself, and which, though
inaccurate as a medical definition, may be held sufficiently descriptive
of one character of the various kinds of disorder with which this
painful symptom may be found allied.

A very singular and interesting illustration of such combinations as Dr.
Hibbert has recorded of the spectral illusion with an actual disorder,
and that of a dangerous kind, was frequently related in society by the
late learned and accomplished Dr. Gregory of Edinburgh, and sometimes, I
believe, quoted by him in his lectures. The narrative, to the author's
best recollection, was as follows:--A patient of Dr. Gregory, a person,
it is understood, of some rank, having requested the doctor's advice,
made the following extraordinary statement of his complaint. "I am in
the habit," he said, "of dining at five, and exactly as the hour of six
arrives I am subjected to the following painful visitation. The door of

and indignation which could characterize her who haunted the merchant
Abudah in the Oriental tale; she rushes upon me, says something, but so
hastily that I cannot discover the purport, and then strikes me a severe
blow with her staff. I fall from my chair in a swoon, which is of longer
or shorter endurance. To the recurrence of this apparition I am daily
subjected. And such is my new and singular complaint." The doctor
immediately asked whether his patient had invited any one to sit with
him when he expected such a visitation. He was answered in the negative.
The nature of the complaint, he said, was so singular, it was so likely
to be imputed to fancy, or even to mental derangement, that he had
shrunk from communicating the circumstance to any one. "Then," said the
doctor, "with your permission, I will dine with you to-day,
_tete-a-tete_, and w
