The Serbs connect the vampire and the were-wolf together, and call them by one name vlkoslak. These rage chiefly in the depths of winter: they hold their annual gatherings, and at them divest themselves of their wolf-skins, which they hang on the trees around them.

If any one succeeds in obtaining the skin and burning it, the vlkoslak is thenceforth disenchanted.

The power to become a were-wolf is obtained by drinking the water which settles in a foot-print left in clay by a wolf.
