* Pages 40-41 (October 1919) are somewhat duplicated, possibly a printing error or errata inserted directly into the work. The version of page 40 that is on scan page 60 is missing a large quantity of text (in comparison to the version of page 40 on scan page 58.)
The following pages in this file are missing: (August 1921) pp. 208. Placeholders should be inserted so that when the pages are inserted, existing content will not become misaligned.
