This text follows the printed book; all inconsistencies in spelling, hyphenation, lay-out, etc. have been retained, except as mentioned below.
Page 67, form: probably the second group of data should have started with Expenditure.
Page 198, Fig. 64: the rules mentioned on the label do not coincide with those listed in Section 360, and have therefore not been linked.
Page 435, The ruling continues for 52 lines: possibly an error for 12 lines or intended for Fig. 172.
Page 448, ... physical side of books is only less important ...: possibly a word is missing (“slightly” or similar).
Page 495: Section 566 is not present in the original work.
Page 508: there seems to be a heading (nr. 586) missing; references to Section 586 are assumed to point to “General Bibliographies.”
Index: some entries are not in alphabetical order; this has not been changed.
