Transcription notes:

The following typos were fixed:

There are text lines missing on [page 112], which were marked with "[missing text]". The missing text could not be found anywhere, so most likely all subsequent editions reproduced this error. Anyway, the meaning of the paragraph is evident from the context.

The table of contents is [here].

The only illustration present is a low-quality logo of the printing company (Fleming H. Revell) on [page 5].
