20. We had better take "persons" as Universe. We may choose "myself" as 'Middle Term', in which case the Premisses will take the form

I am a-person-who-sent-him-to-bring-a-kitten;		$\scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}$
I am a-person-to-whom-he-brought-a-kettle-by-mistake.

Or we may choose "he" as 'Middle Term', in which case the Premisses will take the form

He is a-person-whom-I-sent-to-bring-me-a-kitten;		$\scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}$
He is a-person-who-brought-me-a-kettle-by-mistake.

The latter form seems best, as the interest of the anecdote clearly depends on his stupidity——not on what happened to me. Let us then make $m$ = "he"; $x$ = "persons whom I sent, &c."; and $y$ = "persons who brought, &c."

Hence,

All $m$ are $x$;		$\scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}$
All $m$ are $y$.

and the required Diagram is
