MythologyWeb has the full text of Sabine Baring-Gould’s Book of Werewolves, one of the creepier reference works of the 1860s.

In America we think of lycanthropes as turning into wolves, but legends actually vary throughout the world. People tend to turn into the most important carnivore in the area: dogs in Greece, tigers in India, bears in Northern Europe, foxes in Japan, leopards in Africa, and jaguars in South America. In Polynesia there are even were-sharks.

Correspondingly, there’s a psychiatric syndrome called clinical lycanthropy, in which people think they’ve turned into animals. Here, too, though, wolves are in the minority. Clinicians have reported patients who thought they’d become cats, horses, birds, tigers, frogs, even bees.

Baring-Gould’s vision was quite a bit darker, but he was a weird guy himself. A Victorian hagiographer, antiquarian, novelist, and scholar, he used to teach with his pet bat on his shoulder. His book wanders from lycanthropy down into grave desecration and cannibalism — kind of an odd area for the guy who wrote “Onward, Christian Soldiers.” To each his own.
