Table 7-9

Table 7-9 has several problems:
1. All the items marked with a lower case 'a' should instead have a dagger on them.

2. The entry for ". (dot)" should also have a dagger on it.

3. In the right hand column for the entry for ". (dot)" the end of the line should have the 'a' table footnote marker.
