In 1926 the society decided to discontinue the regular publication of its Proceedings and to enlarge its Journal. The Proceedings are continued therefore, only for material unsuited to the Journal, the volumes appearing at irregular intervals.
Vols. 1-13, 1907-19, edited by J. H. Hyslop; subsequent volumes by various editors. Watch numbering policy: From 1926- we have substituted pt. for vol. where pt. is normally used.
Vols. 20-21 form a combined volume issued in two parts with continuous paging, published 1928 and 1933, respectively.
