Note 346 — Chapter III
Reading edition
The mnemonics have been written in various forms. Those given above are from Aldrich, and they are the ones that are in general use in England. Wallis in his Institutio Logicae (1687) gives for the fourth figure, Balani, Cadere, Digami, Fegano, Fedibo. P. van Musschenbroek in his Institutiones Logicae (1748) gives Barbari, Calentes, Dibatis, Fespamo, Fresisom. This variety of forms for the moods of figure 4 is no doubt due to the fact that the recognition of this figure at all was quite exceptional until comparatively recently. Compare sections 262, 263.
According to Ueberweg (Logic, § 118) the mnemonics run,—
Barbara, Celarent primae, Darii Ferioque. Cesare, Camestres, Festino, Baroco secundae. Tertia grande sonans recitat Darapti, Felapton, Disamis, Datisi, Bocardo, Ferison. Quartae Sunt Bamalip, Calemes, Dimatis, Fesapo, Fresison.
Ueberweg gives Camestros and Calemos for the weakened moods of Camestres and Calemes. This is not, however, quite accurate. The mnemonics should be Camestrop and Calemop.
Professor Carveth Read (Logic, pp. 126, 7) suggests an ingenious modification of the verses, so as to make each mnemonic immediately suggest the figure to which the corresponding mood belongs, at the same time abolishing all the unmeaning letters. He takes l as the sign of the first figure, n of the second, r of the third, and t of the fourth. The lines (to be scanned, says Professor Read, discreetly) then run
Ballala, Celallel, Dalii, Felioque prioris. Cesane, Camesnes, Fesinon, Banoco secundae. Tertia Darapri, Drisamis, Darisi, Ferapro, Bocaro, Ferisor habet. Quanta insuper addit Bamatip, Cametes, Dimatis, Fesapto, Fesistot.
Professor Mackenzie suggests that, if this plan is adopted, it would be better to take r for the first figure (figura recta, the straightforward figure), n for the second figure (figura negativa), t for the third figure (figura tertia or particularis), and l for the fourth figure (figura laeva, the left-handed figure).
