7. The organs of sense and the moving muscles are alike liable to be
affected with palsy, as in the gutta serena, and in some cases of deafness;
and one side of the face has sometimes lost its power of sensation, but
retained its power of motion; other parts of the body have lost their
motions but retained their sensation, as in the common hemiplagia; and in
other instances both these powers have perished together.

8. In some convulsive diseases a delirium or insanity supervenes, and the
convulsions cease; and conversely the convulsions shall supervene, and the
delirium cease. Of this I have been a witness many times in a day in the
paroxysms of violent epilepsies; which evinces that one kind of delirium is
a convulsion of the organs of sense, and that our ideas are the motions of
these organs: the subsequent cases will illustrate this observation.

Miss G----, a fair young lady, with light eyes and hair, was seized with
most violent convulsions of her limbs, with outrageous hiccough, and most
vehement efforts to vomit: after near an hour was elapsed this tragedy
ceased, and a calm talkative delirium supervened for about another hour;
and these relieved each other at intervals during the greatest part of
three or four days. After having carefully considered this disease, I
thought the convulsions of her ideas less dangerous than those of her
muscles; and having in vain attempted to make any opiate continue in her
stomach, an ounce of laudanum was rubbed along the spine of her back, and a
dram of it was used as an enema; by this medicine a kind of drunken
delirium was continued many hours; and when it ceased the convulsions did
not return; and the lady continued well many years, except some lighter
relapses, which were relieved in the same manner.

Miss H----, an accomplished young lady, with light eyes and hair, was
seized with convulsions of her limbs, with hiccough, and efforts to vomit,
more violent than words can express; these continued near an hour, and were
succeeded with a cataleptic spasm of one arm, with the hand applied to her
head; and after about twenty minutes these spasms ceased, and a talkative
reverie supervened for near an other hour, from which no violence, which it
was proper to use, could awaken her. These periods of c
