Book by Mary Baker Eddy
Science and Health with Key to the Scriptures is the central text of the Christian Science religion. Mary Baker Eddy described it as her "most important work." She began writing it in February 1872 and the first edition was published in 1875. Mrs Eddy closed her college and left Boston in 1889, in order to revise the text for the 50th edition (1891). This consisted of 578 pages plus a 73-page index, and for the first time included marginal headings. The 226th "thousand" (edition) appeared in 1902, and this included "Fruitage," making up the page count of 700 pages which remains to this day. The last numbered edition was the 418th, which appeared in 1906, but further changes were made right up until 1910. Wikipedia, Science and Health with Key to the Scriptures
