wholesomeness. For this we must use the larger Diagram, making x
mean "new", y "nice", and m "wholesome". (Everything INSIDE the
central Square is supposed to have the attribute m, and everything
OUTSIDE it the attribute m', i.e. "not-m".)

You had better adopt the rule to make m mean the Attribute which
occurs in the MIDDLE Term or Terms. (I have chosen m as the symbol,
because 'middle' begins with 'm'.)

Now, in representing the two Premisses, I prefer to begin with the
NEGATIVE one (the one beginning with "no"), because GREY counters
can always be placed with CERTAINTY, and will then help to fix the
position of the red counters, which are sometimes a little uncertain
where they will be most welcome.

Let us express, the "no nice Cakes are unwholesome (Cakes)", i.e.
"no y-Cakes are m'-(Cakes)". This tells us that none of the Cakes
belonging to the y-half of the cupboard are in its m'-compartments
(i.e. the ones outside the central Square). Hence the two compartments,
No. 9 and No. 15, are both 'EMPTY'; and we must place a grey counter
in EACH of them, thus:--
