Never having been ill, he had never examined nor treated himself:
medicine was good for others but useless for him. With a machine
organized like his he need fear only accidents, and until now he had been
spared them; a true son of peasants, he victoriously resisted Paris life
as the destroyer of the intellect. But the time had come to undertake an
examination and to try a treatment that would give him rest. He was not
a sceptical doctor, and he believed that what he ordered for others was
good for himself.

The misfortune was that he could not find in himself any of the causes
which resolve into insomnia; he had neither meningitis nor brain fever,
nor anything that indicated a cerebral tumor; he was not anaemic; he ate
well; he did not suffer with neuralgia, nor with any acute or chronic
affection that generally accompanied the absence of sleep; he drank
neither tea nor alcohol; and without this state of over-excitement of the
encephalic centres, he might have said that he was in good health, a
little thin, but that was all.

It was this excitement that he must cure, and as there are many remedies
for insomnia, he tried those which, it seemed to him, were suitable to
his case; but bromide of potassium, in spite of its hypnotic properties,
produced no more effect than the over-working of the brain and body.
When he realized this he replaced it with chloral; but chloral, which
should create a desire to sleep, after several days had no more effect
than the bromide. Then he tried injections of morphine.

It was not without a certain uneasiness that he made this third trial,
the first two having met with so little success; and since it is
acknowledged that chloral produces a calmer sleep than morphine, it
