    Let "persons" be Universe; $m$ = "Jews"; $x$ = "that are in the house"; $y$ = "that are in the garden".

    No $m$ are $x$; No $m^{\prime }$ are $y$.

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

    ∴ No $x$ are $y$.

    i.e. No persons, that are in the house, are also in the garden.

    Let "Things" be Universe; $m$ = "noisy"; $x$ = "battles"; $y$ = "that may escape notice".

    All $x$ are $m$; All $m^{\prime }$ are $y$.

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

    ∴ Some $x^{\prime }$ are $y$.

    i.e. Some things, that are not battles, may escape notice.
