he was, without doubt, deeply interested in her case. He dabbled a little in mesmerism and sometimes experimented on Mary, whom he found a sensitive subject. He discovered that he could partly control her movements by mental suggestion. "I can make that girl stop in the street any time merely by willing it," he used to tell his friends, and he often demonstrated that he could do it.
Mesmerism was a new subject in New England in those days, and there was much experimenting and excitement over it. There is no doubt that it formed one of the early influences in Mrs. Eddy's life, and that it left an indelible impression upon her supersensitive organisation. Charles Poyen, a French disciple of Mesmer, had travelled through New England, lecturing and performing marvels of mesmeric power in the same towns in which Mrs. Eddy then lived. In his book, Animal Magnetism in New England, which was published in 1837, he gives an account of his experiences there and says: "Animal magnetism indisputably constituted in several parts of New England the most stirring topic of conversation among all classes of society." He called it a "great Truth," "The Power of Mind Over Matter," a "demonstration," a "discovery given by God," and a "science." Whether or not Mary Baker saw or heard Poyen, or read his book, she must have heard of his theories, and must have been familiar with the phrases he used, as they were matter of common household discussion and would appeal strongly to a girl of Mary's temperament. In Christian Science she has given an important place to "Animal Magnetism," and there is a chapter devoted to it in her book, Science and Health.
