The cross appears in a few spots. What does it mean?
This character is called a
dagger, and is used to indicate a footnote when the asterisk
* has already been used. Usually, when there's more footnotes, people tend to use multiple asterisks to indicate to which footnote something relates, but this is another way of doing it.
There's also a double and triple dagger, for when an asterisk and a dagger are not enough for your footnote needs.
