These chapters were first printed in “The Builder” during the year 1921. For that reason, and because the earlier records of Roman discoveries in London given in this Journal seemed to have been less worked over than other sources, a large number of references are given to its pages. The account of Roman London in the “Victoria County History,” C. Roach Smith’s “Illustrations of Roman London,” and Mr. T. Ward’s “Roman Era in Britain,” and “Roman British Buildings,” may be specially mentioned among the works consulted. The first named is cited as V.C.H. Mr. A. H. Lyell’s “Bibliographical List of Romano-British Remains” (1912) is indispensable to the student.
