English translation. According to the note in the translation file, the translation was made by Prof. Hisada with the help of a translator, and covers the text through Chapter 2. The note says the translation may not be accurate, especially in the parts highlighted in yellow; these parts are marked on the translation page.

Japanese original. The preface and the first part of Chapter 1 are taken from the Japanese manuscript file provided by Prof. Hisada. Its content is the same as the page images on the former site that were taken from the memorial booklet of the gathering in memory of Prof. Aki (pages 1–13). The latter part of Chapter 1 and Chapter 2 were transcribed from the page images on the former site (pages 15–23); according to the former site, these pages were provided by Prof. Aki’s wife, Valerie Aki, and his younger brother, Shuichi Aki. The memorial-booklet version ends Chapter 1 differently, and that ending is included as an appendix to the Japanese text.
