4.10. Footnotes and marginal notes 115
If there are a number of \footnotemark commands without optional
arguments appearing before the next \footnotetext command, it is
necessary to adjust the counter with the command
\addtocounter{footnote}{dif }
where dif is a negative number saying how many times the counter must
be set back. Then before every \footnotetext command, the counter
must be incremented by one. This can be done either with the command
\addtocounter, with dif =1, or with the command
\stepcounter{footnote}
which adds 1 to the given counter.
For example: mosquitoes 3 and elephants 4
For example: \fbox{mosquitoes\footnotemark\ and
elephants\footnotemark}
generates the footnote markers 3 and 4 . Now the counter has the value 4.
In order for the first \footnotetext outside the framed box to operate
with the correct counter value, it must first be decremented by one. The
two footnote texts are made with
\addtocounter{footnote}{-1}\footnotetext{Small insects}
\stepcounter{footnote}\footnotetext{Large mammals}
immediately following the \fbox{} command. The footnote counter now
has the same value as it did on leaving the \fbox.
4.10.4 Footnotes in minipages
As mentioned in Section 4.10.1, footnote commands are allowed inside
the minipage environment. However, the footnote appears underneath
the minipage, not below the main page.
Footnote commands within a minipage
a have a different marker style.
The footnote comes after the next
\end{minipage} command. b Minipage
footnotes have a counter separate from
that of the main page, called mpfootnote,
counting independently of footnote.
a The marker is a raised lower-case letter.
b Watch out for nested minipages.
\begin{minipage}{6cm}
Footnote commands within
a minipage\footnote{The
marker is a raised
lower-case letter.} have

Footnotes within a tabular environment can normally only be generated
! with the commands described above: \footnotemark within the table and
