 1      I, 1 | nature of a perfect and of an imperfect syllogism; and after that,
 2      I, 1 |       follows; a syllogism is imperfect, if it needs either one
 3      I, 5 | syllogisms in this figure are imperfect: for all are made perfect
 4      I, 6 | syllogisms in this figure are imperfect (for all are made perfect
 5      I, 7 |     is clear too that all the imperfect syllogisms are made perfect
 6      I, 14| results in the first case, an imperfect in the second. But possibility
 7      I, 15|    all the syllogisms will be imperfect, and those which are negative
 8      I, 15|      be evident that they are imperfect: for the proof proceeds
 9      I, 15|    all cases there will be an imperfect syllogism. Only some of
10      I, 16|       all C. We shall have an imperfect syllogism to prove that
11      I, 16|   belong to all C. That it is imperfect is clear from the proof:
12      I, 16|        and it is perfect, not imperfect: for it is completed directly
13      I, 16|   that all the syllogisms are imperfect and are perfected by means
14      I, 19|   that all the syllogisms are imperfect, and are completed by means
15      I, 22| syllogisms in this figure are imperfect, and that they are made
16     II, 7 |      of circular proof or are imperfect.~
