The book says these syllogisms fall within the four figures, but this brief passage explicitly illustrates figures one, two, and three. It does not supply a separate fourth-figure example here.
The fourth figure can still be understood through placement of the common component; it should not be attributed to the source through an invented quotation.
This distinction separates the generality of a rule from the examples actually printed.
