Lucerne, a peasant was attacked by a wolf, whilst he was hewing
timber; he defended himself, and smote off a fore-leg of the beast.
The moment that the blood began to flow the wolf's form changed, and
he recognized a woman without her arm. She was burnt alive.

An evidence that beasts are transformed witches is to be found in
their having no tails. When the devil takes human form, however, he
keeps his club-foot of the Satyr, as a token by which he may be
recognized. So animals deficient in caudal appendages are to be
avoided, as they are witches in disguise. The Thingwald should
consider the case of the Manx cats in its next session.

Forestus, in his chapter on maladies of the brain, relates a
circumstance which came under his own observation, in the middle of
the sixteenth century, at Alcmaar in the Netherlands. A peasant there
was attacked every spring with a fit of insanity; under the influence
of this he rushed about the churchyard, ran into the church, jumped
over the benches, danced, was filled with fury, climbed up, descended,
and never remained quiet. He carried a long staff in his hand, with
which he drove away the dogs, which flew at him and wounded him, so
that his thighs were covered with scars. His face was pale, his eyes
deep sunk in their sockets. Forestus pronounces the man to be a
lycanthropist, but he does not say that the poor fellow believed
himself to be transformed into a wolf. In reference to this case,
however, he mentions that of a Spanish nobleman who believed himself
to be changed into a bear, and who wandered filled with fury among the
woods.
