This is the conclusioun to knowe the ascensions of signes in the right cercle, that is circulus directus.

Set the heved of what signe the lyst to knowe his ascendyng in the right cercle upon the lyne meridionall, and wayte where thyn almury touchith the bordure, and set there a prikke; turne than thy riet westward til that the ende of the forseide signe sitte upon the meridional lyne and eftsonys wayte where thin almury touchith the bordure, and set there another pricke. Rekene than the nombre of degres in the bordure bitwixe bothe prikkes, and tak the ascensioun of the signe in the right cercle. And thus maist thou werke with every porcioun of thy zodiak.
