Here they are:

\makeatletter

\newcommand\xl at sh@ft[1]{%

  \dimen@ #1%

  \multiply\dimen@\m at ne

  \kern\strip at pt\fontdimen\@ne\font\dimen@}


\newcommand{\existential}{%

  \ensuremath{\mathord{%

    \ifnum\XeTeXcharglyph"018E>0%

      \mbox{\char"018E}%

    \else

      \reflectbox{E}%

    \fi}}}


\newcommand{\universal}{%

  \ensuremath{\mathord{%

    \setbox\z@\hbox{A}%

    \dimen@\ht\z@

    \advance\dimen@\dp\z@

    \ltx at sh@ft\dimen@

    \raise\dimen@\hbox{\rotatebox{180}{\box\z@}}%

    \xl at sh@ft\dimen@}}}


\newcommand{\definitedescription}{%

  \ensuremath{\mathord{%

    \setbox\z@\hbox{$\iota$}%

    \dimen@\ht\z@

    \advance\dimen@\dp\z@

    \ltx at sh@ft\dimen@

    \raise\dimen@\hbox{\rotatebox{180}{\box\z@}}%

    \xl at sh@ft\dimen@}}}


\makeatother


Copy and paste that into your document (or a new file and make reference to
that file in your document). Then you can use \universal, \existential and
\definitedescription (or you can choose other names). Note that you will
need to load the graphicx package with \usepackage{graphicx}.

For reference, they are derived from my metalogo package, which borrows from
xltxtra.
