Let "creatures" be Universe; $m$ = "that run well"; $x$ = "fat"; $y$ = "greyhounds".

No

x

are

m

;
Some

y

are

m

.

\scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}

∴ Some

y

are

x^{\prime }

.

i.e. Some greyhounds are not fat.

Let "persons" be Universe; $m$ = "soldiers"; $x$ = "that march"; $y$ = "youths".

All

m

are

x

;
Some

y

are

m^{\prime }

.

\scriptstyle {\left.{\begin{matrix}\ \\\ \end{matrix}}\right\}\,}
