Transcriber’s Notes

Inconsistent, archaic and unusual transcriptions, spelling,
hyphenation, punctuation, use of accents, etc. (including in names)
and repeated information have been retained (even when occurring on
the same page or in the same sentence), except as mentioned below. The
use of periods, mid-level decimal points and commas in numbers has not
been standardised.

Plate II: the data as mentioned in the errata have not been corrected
in the Plate.

Page 51-52, table, last column: 199 and 1877 are not in the range of
years under consideration.

Page 97, table header: the years are out of order, possibly
erroneously.

Page 203: the table header does not appear to agree with the contents;
presumably, the first group of rows refers to 1876.

Page 209, column Pic 16, row 14: 4·11 does not fit with the other data
and may be an error for 8·11

In the source document, the Plates are not always printed in numerical
order (see also the List of Plates), this has not been changed.

Unless mentioned below under “Changes Made”, all (tabulated or text)
data and calculations are presented as printed in the source document,
even when there are obvious errors or inconsistencies in these data or
calculations.

Changes made

Some footnotes, tables and illustrations moved; some tables re-
arranged.
Some minor obvious typos have been corrected silently.
R.L. and R. L. have been standardised as R. L., spaces between numbers
and percent signs have been removed where present.

some minor lay-out inconsistencies have been resolved.
