 1      I, 7 |     the middle figure can be reduced to universal syllogisms
 2      I, 7 |      the first figure can be reduced to syllogisms in the middle
 3      I, 7 | particular syllogisms can be reduced to universal syllogisms
 4      I, 7 |  these (we have seen) may be reduced to the universal syllogisms
 5      I, 7 |   the third figure may be so reduced. It is clear then that all
