133115IN LIB. IIII. qua vìſuntur. ABACILATITVDOITA
HABEAT RATIONEM. Si ima colũnæ
craſſitudinem quadrato clauſam, circulo cinxeris, eum
ipſum alio quadrato includas, quæ ad angulos ducentur
lineæ, duplo maiores erunt, imi Scapi diametro, ea erit
iusta Abaci latitudo, qui ſinuatur nonnullis hoc modo.
Collocant eum ad Regulam expolitum latum quátum di-
ximus & quàm magna est frontis eius linea, deſc ribunt
parium laterum triangulum. Quo autem ſpacio ſupera-
tur ea latitudine craſſitudo Scapi imi, id diuidentes in
parteis quatuor, tum circini crure in angulo infimo con-
stituto, alterum mobile ad tertiam vſ earum quæ ſupe-
rant craſſitudinem Scapi deductam, per frontis angulos
ita circũagunt, vt ablatis tribus, retenta vna, ſinuetur de-
lumbetur & fornicetur nona ferè ſuæ latitudinis parte,
at vbi linea circinationis later a trianguli tanget, eum
putant eſſe cornuum Abaci terminum. Quidam facto
triangulo quẽ diximus, ab angulis extremis Abaci in in-
teriorem partem recedentes hinc at hinc parte decima
octaua, collocato circini centro vno in angulo trigoni imo,
altero per eas receſſiones ducto, circinant, eum eſſe cor-
nuum terminũ aiunt. Nonnulli frontem Abaci ab extre-
mis angulis totam dimetiẽtes in partes nouem, ex eis par-
tem vnam in medio collocant, reliquis octo propendenti-
bus, in quarum ima circinum conſtituũt, diducunt ad no-
nam illam, hinc at hinc agentes ad lineam frontis, termi-
nant cornua vbi circinus tangit lineá frontis. Omnium
ſinuandi ratio non diſplicet, ſed videntur mihi in cornuũ
finitione errare, & qui extra quadratum petunt, & qui in
quadrato ſecant, neutro enim modo Abaci latitudo
