Ordered and calculated values of magnetic elements for Itoigawa at Table XVI.

This thumbnail map stands out for its minimalism. The shrine is likely Akiba Jinja (秋葉神社), here.

In his preface (vi-vii), Tanakadate dismisses the orthographical reformation proposed by the Government Committee for the Improvement of the Language (“to which the writer is an opponent”), and apologizes for tardiness in publication (needlessly, given the formidable challenges of this project, including not least the difficult composition (figures, in many more than 900 tables), and preparation of (55 or so) observational diagrams and (320) maps).
