Those using editions of Science and Health previous to the 36th are often at a loss to find passages referred to, as writers usually give the paging of the revised edition. This can be easily remedied by penciling the corresponding number of page of the other edition, at the bottom of each page where changes are made, according to the following directions:
Old ed. 13 to 74, 75 to 138, 139 to 167, 168 to 210.
Rev. ed. 149 to 210, 59 to 119, 120 to 148, 13 to 55.
Open the book to page thirteen and at the bottom pencil 149, marking each succeeding page with the next consecutive number to the end of the chapter at page seventy-four, which will give 210 at the bottom. Now take the next set of numbers, beginning at page seventy-five, putting 59 at the bottom, as before, to the end of the numbers given. From the chapter on Animal Magnetism to the end there is no change, except in the wording of some sentences. Pages 181 and 182 are entirely different in the revised edition.
