This is actually /Japanese Self-Taught and Grammar/, which is William J. S. Shand's /Japanese Self-Taught/ in one volume with Henry John Weintz's /Japanese Grammar Self-Taught/ (beginning at p. 120 in this scan). See p. 121 in the scan, as well as the discussion of this book and its authors, https://www.degruyter.com/document/doi/10.1515/9781898823469-035/pdf Noboru Koyama, “William J.S.
