 2 3      |                                    3. The moder of thin Astrelabye is thikkest plate,
 3 5      |                         here the foure quarters of thin Astrolabie divided after
 4 7      |                    proporcioun is every quarter of thin Astrolabie divided. Over
 5 13     |                           and eke by mediacioun of thin eye to knowe the altitude
 6 18     |                           point over the crowne of thin heved. And also this cenyth
 7 19     |                           dividen the orisounte of thin Astrelabie in 24 divisiouns.
 8 21     |                                    21. The riet of thin Astrelabie with thy zodiak,
 9 21     |                       sitting within the zodiak of thin Astrelabie ben clepid sterres

11 21     |                             for the streitnesse of thin Astrolabie, than is every
12 21     |                         governaunce; as Aries hath thin heved, and Taurus thy nekke
13 21     |                       nekke and thy throte, Gemini thin armholes and thin armes,
14 21     |                           Gemini thin armholes and thin armes, and so furth, as
15 21     |                           label shalt thou calcule thin equaciouns in the bordure
16 21     |                       equaciouns in the bordure of thin Astralabie, as by thin almury. ~
17 21     |                          of thin Astralabie, as by thin almury. ~Thin almury is
18 21     |                    Astralabie, as by thin almury. ~Thin almury is clepid the denticle
19 2      |                           fro the litel crois upon thin est lyne, and tak there
20 3      |                    almykanteras on the est syde of thin Astrelabie; and if it be
21 3      |                           take a just ascendent by thin Astrelabie, or elles to
22 5      |                       muche as the almykanteras in thin Astrelabie ben compowned
23 5      |                            to knowe and worke with thin owne instrument. Wherfore
