In a few sentences, describe how this passage is a satire of Aunt Polly's superstitious habits:
She was a subscriber for all the “Health” periodicals and phrenological frauds; and the solemn ignorance they were inflated with was breath to her nostrils. . . . She was as simple-hearted and honest as the day was long, and so she was an easy victim. She gathered together her quack periodicals and her quack medicines, and thus armed with death, went about on her pale horse, metaphorically speaking, with “hell following after.” But she never suspected that she was not an angel of healing and the balm of Gilead in disguise, to the suffering neighbors.
