The _Banner of Light_ advertisement was dated July 4, 1869, and one of the contracts is dated August 17, 1870, so it will be seen how brief was the duration of Mrs. Eddy’s guarantee system of operating. I think, in all her lawsuits for the recovery of tuition Mrs. Eddy never prevailed after a hearing upon the merits, and in one of them, the Judge, who tried her case, after having heard her testimony in full, said: “I do not find any instruction given by her nor any explanations of her ‘science’ or ‘method of healing,’ which are intelligible to ordinary comprehension, or which could in any way be of value in fitting the defendant as a competent and successful practitioner of any intelligible art or method of healing the sick. And I am of opinion that the consideration for the agreement has wholly failed, and I so find.” This finding of the court is interesting as a judicial estimate, based upon her own sworn testimony, of the value of Mrs. Eddy’s Christian Science, which has never been any more intelligible to any one else than it was to the learned Judge. In 1881, Mrs. Eddy established what she called the Massachusetts Metaphysical College, which was an institution for the turning out of Christian Science healers. Her adopted son and husband, with herself, constituted the faculty of this remarkable institution, and the entire college course consisted of twelve lessons. The following is taken from an advertisement in the _Christian Science Journal_, Mrs. Eddy’s personal organ, for September, 1886, under the heading, “Massachusetts Metaphysical College, Rev. Mary Baker G. Eddy, President, 571 Columbus Ave., Boston, Mass.”: “The collegiate course in Christian Science metaphysical healing includes twelve lessons. Class convenes at 10 a.m. The first week, six consecutive lessons. The term continues about three weeks. _Tuition, three hundred dollars. Tuition for all strictly in advance_.” Remember that this was Mrs. Eddy’s charge fifteen years after God had, by revelation, as she says, freely imparted to her what she was here advertising to sell at the rate of twenty-five dollars per lesson, cash “strictly in advance.” Mrs. Eddy’s was a strictly cash business, no trust, no “revelation” C.O.D., or on the installment plan, and no money returned however dissatisfied with the purchase. Referring to this charge of three hundred dollars for twelve lessons, Mrs. Eddy, in her book, “Retrospection and Introspection,” has perpetrated one the funniest passages to be found in all literature:
