Note 308 — Chapter V · Magic Rites connected with the Several Departments of Nature (continued 2)

“A strange superstition is attached to a small snail which frequents the neighbourhood of the limestone hills in Perak. It belongs to the Cyclophoridæ, and is probably an Alycæus. Among the grass in the shadow of a grazing animal these creatures are to be discovered, and if one of them is crushed it will be found to be full of blood, which has been drawn in a mysterious way from the veins of the animal through its shadow. Where these noxious snails abound, the cattle become emaciated and sometimes even die from the constant loss of blood. In the folklore of other countries many parallels to this occur, but they differ in either the birds, bats, or vampires, who are supposed to prey on the life-blood of their fellows, going direct to the animals to suck the blood, instead of doing so through the medium of their shadows.”308
