and that these two, when combined, give us

We have now to mark the two positive portions, "some ${\displaystyle x}$ are ${\displaystyle m^{\prime }}$" and "some ${\displaystyle y}$ are ${\displaystyle m}$".

The only two compartments, available for Things which are ${\displaystyle xm^{\prime }}$, are No. 9 and No. 10. Of these, No. 9 is already marked as 'empty'; so our red counter must go into No. 10.

Similarly, the only two, available for ${\displaystyle ym}$, are No. 11 and No. 13. Of these, No. 11 is already marked as 'empty'; so our red counter must go into No. 13.

The final result is
