The five books of Boethius (in vol. ii.) are denoted by B 1, B 2, B 3, B 4, B 5, respectively; and the 'prose' and 'metrical' sections are denoted by 'p' and 'm'. Thus, under 'Abaissen,' the reference 'B 4. p 7. 56' means 'Boethius, bk. iv. prose 7, line 56.' The five books of Troilus (also in vol. ii.) are denoted by T. i., T. ii., T. iii., T. iv., and T. v. Thus 'T. iii. 1233' means 'Troilus, bk. iii., line 1233.' The House of Fame and the Legend of Good Women (in vol. iii.) are denoted by 'HF.' and 'L.' respectively. If, in the latter case, the italic letter '_a_' follows the number of the line, the reference is to the earlier (or A-text) of the Prologue to the Legend. Thus 'HF. 865' means 'House of Fame, line 865.' Again, 'L. 2075' means 'Legend of Good Women, line 2075'; and 'L. 200 _a_' means 'Legend, &c., line 200 of the text in the upper part of the page.' The Prologue and the two books of the Treatise on the Astrolabe (in vol. iii.) are denoted, respectively, by 'A. pr.', 'A. i.', and 'A. ii.' Thus, under 'Abate', the reference 'A. ii. 10. 8' means 'Astrolabe, bk. ii. s. 10, line 8'; and 'A. pr. 10' means 'Astrolabe, prologue, line 10.' References to the Canterbury Tales (in vol. iv.) are known by the use of the letters A, B, C, D, E, F, G, H, and I, which are used to denote the various Groups into which the Tales are divided. In this case, 'A' is never followed by a full stop or by Roman numerals, as when the 'Astrolabe' is referred to; and such a reference as 'B 5,' meaning line 5 of Group B, is quite distinct from 'B 5. p 1. 1,' where 'B 5' means bk. v. of Boethius, and is invariably accompanied by the 'p' or 'm' denoting the 'prose' or 'metre.'
