Note I.——Large Roman numerals standing alone indicate volumes. Small Roman numerals standing alone indicate chapters. Arabic numerals standing alone indicate pages. In other cases the divisions are explicitly stated. Thus "Rashdall, Universities of Europe, I, ix" refers the reader to the ninth chapter of the first volume of that work; "I, p. ix" would indicate the ninth page of the preface of the same volume.
Note II.——Where St. Thomas (Aquinas) is cited without the name of any particular work the reference is always to "Summa Theologica" (not to "Summa Philosophiæ"). The divisions of the "Summa Theol." are indicated by a system which may best be understood by the following example: "I-II, Q. vi, a. 7, ad 2 um" refers the reader to the seventh article of the sixth question in the first part of the second part, in the response to the second objection.
Note III.——The abbreviations employed for the various books of the Bible are obvious. Ecclesiasticus is indicated by Ecclus., to distinguish it from Ecclesiastes (Eccles.). It should also be noted that I and II Kings in D. V. correspond to I and II Samuel in A. V.; and I and II Par. to I and II Chronicles. Where, in the spelling of a proper name, there is a marked difference between the D. V. and the A. V., the form found in the latter is added, in parentheses.
