added Hindu-Arabic apices
Also, it must be recognized that the first four words of the first verse begin with these consonants, b c d f, like all the other words that follow. By this it must be understood that all the moods indicated by a word beginning with b are to be reduced to the first mood of the first figure, and all the moods signified by a word beginning with c to the second mood, those beginning with d to the third and those with f to the fourth. Also, wherever an s is put in these words, it signifies that the proposition understood by the immediately preceding vowel is to be converted simply. And by p it signifies that the proposition is to be converted accidentally. Wherever m is put, it signifies that a transposition in premises is to be done, and a transposition is making a minor out of a major, and the converse. Where c is put, however, it signifies that the mood understood by that word is to be confirmed by impossibility.

Rara Arithemeca, Halliwell 1839, p. 108:
"in the library just mentioned [of Trinity College], there is a list of [numerical contractions], on a fly-leaf to a MS. of [the Geometry of Boethius], in a hand-writing of the fourteenth century, which is thus headed :
Primus igin; andras; ormis; quarto subit arbas;
Quinque quinas ; termas ; zenis ; temenias ; celentis.
and over these names the contractions are written, as well as Roman numerals explaining them."
Rara Arithemeca, Halliwell 1839, p. 109:
"The following verses occur in a MS. of the fourteenth century on arithmetic [Bib.Trin.Coll.Cant.interMSS.Gal.O.2.45.f.33b] :
Unus adest igin ; andras duo ; tres reor armin ;
Quatuor est arbas ; et per quinque fore quinas ;
Sex calcis ; septem zenis ; octo zenienias;
Novem celentis ; per deno sume priorem.
And a list of the contractions is given on the preceding page of the same volume."
