school and was given to inventing strange falsehoods. In one
instance, he asserted that he had killed and robbed a man, although it
was known that he had not left the house during the time.

After six months in prison, he began to show signs of mental alienation,
with insomnia, loss of speech, and coprophagy. Whenever the cells were
opened, he made wild attempts to escape by climbing up the grating. He
was often seized with epileptic convulsions.

On the 30th of August, 1899, he was examined medically with the
following results:

Stature, 5 ft., 1 in. (1.55 m.); weight, 130 lbs. (59 kilogrammes).
Other measurements could not be obtained, owing to the subject's
obstinate resistance. His skeletal constitution appeared to be regular
and his body well nourished. His skull was brachycephalic, with strongly
developed frontal sinuses, and fine, long, dark-brown hair. In the
parieto-occipital region were a scar and lesion of the bone, the marks
of a wound received during one of his dishonest adventures. He had a
normal type of face with frequent contractions of the mimic muscles; the
hair-growth on the face scanty for his age. Extremely mobile eyes of
vivacious expression, slight strabismus. An examination of the mouth
showed a slight obliqueness of the palate, and the mucous membrane was
rather pale. The colourless skin was inclined to sallowness.

The functions showed an extraordinary degree of cutaneous anaesthesia and
analgesia. In winter and summer the patient wore only a pair of trousers
and a thin jersey covering his chest and leaving the arms bare; these he
was fond of adorning with ribbons and medals. He was in the habit of
slipping pieces of ice between his clothing and skin, and pricking
himself on the chin with a needle for the purpose of inserting hairs in
the holes. On one occasion, one of the doctors came quietly behind him
and thrust a needle rather deeply into the nape of his neck, apparently
without producing any sensation. Various tests were made by pricking him
with a needle when asleep, but without causing the slightest reflex
movement on his part.

_Psychology._ He was subject to strange impulses, which appeared to be
irresistible. On one occasion he was caught cutting off the head of a
cat, and at times he would devour mice, spiders, nails, excrements, and
the sputum of the other patients. He committed acts of self-abuse
publicly, with ostentatious indecency; was in the habit of snatching at
