ible that he
might use it afterwards."
"I should like to have that a little clearer," said the judge,
interposing. "Do you mean to get the weapon for another, possibly quite
innocent purpose, and then use it for an act of violence?"
"Yes, my lord," replied Sir Henry. "That is quite consistent with an
attack of petit mal."
"When a man has periodical attacks of petit mal, would it not be
possible, by observation of him between the attacks, or when he was
suffering from the attacks, to tell whether he had a tendency to them?"
"No, only in a very few and exceptional cases."
"In your opinion epilepsy is an hereditary disease?"
"Undoubtedly."
"Are you aware that certain eminent French specialists, including Marie,
are of the opinion that hereditary influences play a very small part in
epilepsy?"
"That may be." Sir Henry dismissed the views of the French specialists
with a condescending wave of his fat white hand.
"That does not alter your own opinion?"
"Certainly not."
"And do you say that because this man's mother suffered from epilepsy
the chances are that he is suffering from it?"
"Pardon me, I said nothing of the kind. I think the chances are that he
would have a highly organised nervous system, and would probably suffer
from some nervous disease. In the case of the prisoner, I should say
that shell-shock increased his predisposition to epilepsy."
"Do you suggest that shell-shock leads to epilepsy?"
"In general, no; in this particular case, possibly. A man may have
shell-shock, and injury to the brain, which is not necessarily
epileptic."
"It is possible for shell-shock alone to lead to a subsequent attack of
insanity?" asked the judge.
"It is possible--certainly."
"How often do these attacks of petit mal occur?" asked Sir Herbert.
"They vary considerably according to the patient--sometimes once a week,
sometimes monthly, and there have been cases in which the attacks are
separated by months."
"Are not two attacks in twenty-four hours unprecedented?"
"Unusual, but not unprecedented. The excitement of going from one place
to another, and walking miles to get there, would be a predisposing
factor. Prisoner would have been suffering from the effects of the first
attack when he left the Durrington hotel, and the excitement of the
change and the fatigue of walking all day would have been very
prejudicial to him, and account for the second and more violent attack."
