Transcriber's Notes
Obvious punctuation errors repaired.
Seven instances of "manhole" and nine of "man-hole" were retained.
"Octopus" is spelled "octupus" in this volume. This was changed in the table of contents and a chapter header to reflect text usage.
One instance each of Penson/Pensen was retained.
The remaining corrections made are indicated by dotted lines under the corrections. Scroll the mouse over the word and the original text will appear.
