Omens and Superstitions of Southern India 

Excerpt: "In many villages, during the festival to the village deity, water is poured over a sheep’s back, and it is accepted as a good sign if it shivers. "When the people are economical, they keep on pouring water till it does shiver, to avoid the expense of providing a second victim for sacrifice. But, where they are more scrupulous, if it does not shiver, it is taken as a sign that the goddess will not accept it, and it is taken away.""
