Transcriber’s notes

The text contains some inconsistencies in the usage of hyphens. Only those have been corrected where the majority was spelled otherwise. All corrections made are listed below.

To represent formatting the following conventions are used: _word_ means that “word” is in italics; +word+ means that “word” is in small capitals; =word= means that “word” is in bold.

The asterism (⁂) on page 8 should be inverted, but this was not possible to achieve since no such symbol exists.
