Inconsistent and unusual spelling, capitalisation and hyphenation have
been retained, unless mentioned below. The discrepancies between the
General List of Contents and the structure of the text have not been
corrected.
Depending on the hard- and software used to read this text and their
settings, not all elements may display as intended. Where scales are
given for illustrations, these can, of course, not be relied upon for
measurements.
The numbering of illustrations in the book is inconsistent.
Illustrations that have no numbered captions may or may not be
counted; this has not been standardised, except as listed below.
Missing illustration numbers have been added only where they are
referenced in the text. The illustrations referred to in the text as
Figs. 242 and 243 are captioned Fig. 243 and 244.
Page 65-69 and Figs. 66-71: the text uses upper case reference
letters, the illustrations lower case, which has not been
standardised.
Page 84, table of symbols: the source document uses letters (O and L)
rather than symbols for circle and angle.
Page 94, Bisect two of the angles _A C_ of the triangle: presumably
the unmarked point A is in the lower left-hand corner of the
illustration.
Page 113, The tee-square, as shown, ...: there is no illustration with
the relevant reference numbers; probably the reference is to Fig.
151/152.
Page 239, rough irregular lines, as in fig. 134, on page 131: there is
no Fig. 134 on page 131; page 134 nor page 131 show the rough
irregular lines. Several other illustrations in the book do show such
lines.
Index: the order of entries is as printed in the source document.
Changes made:
Illustrations and Notes have been moved out of text paragraphs.
Some obvious minor punctuation and typographical errors have been
corrected silently.
In some tables the ditto symbol („) has been replaced with the dittoed
text; some tables have been split or re-arranged. The use of × and x
in multiplications and dimensions has been standardised to ×.
Page 48: Figure numbers 45-49 added to illustration.
Page 89: and on _B_ on _B I_ changed to and on _B_ on _B D_.
Page 177: D = diam. of collar changed to d = diam. of collar.
Page 193: Bbt.--Babbit. changed to Bbt.--Babbitt.
Page 203: as described on page 191 changed to as described on page
199.
Page 214: 4 tenths measured at the 2′ line changed to 4 tenths
measured at the 2″ line.
