this vampire which is amongst us is of herself so strong in person as twenty women , she is of cunning more than mortal , for her cunning be the growth of ages , she have still the aids of necromancy , which is , as her etymology imply , the divination by the dead , and all the dead that she can come nigh to are for her at command ; she is brute , and more than brute ; she is devil in callous , and the heart of her is not ; she can , within her range , direct the elements , the storm , the fog , the thunder ; she can command all the meaner things , the rat , and the owl , and the bat , the moth , and the fox , and the wolf , she can grow and become small ; and she can at times vanish and come unknown .
