 1 19|          of the sonne and of every sterre. ~
 2 3 |        altitude of the faire white sterre that is clepid Alhabor,
 3 3 |         sey I by the centre of eny sterre fix by nyght. And more over,
 4 7 |         thou se how longe that eny sterre fix dwelleth above the erthe,
 5 13|            heighest cours that eny sterre fix clymbeth by night. This
 6 13|           is to seyn that whan eny sterre fix is passid the lyne meridional,
 7 17|          verrey degre of eny maner sterre, straunge or unstraunge,
 8 17|           Tak the altitude of this sterre whan he is on the est syde
 9 17|           anon right by som manere sterre fix which that thou knowist;
10 17|         the altitude of the firste sterre ne thyn ascendent. And whan
11 17|   diligently whan this same firste sterre passith eny thyng the south
12 17|           anon-ryght by som manere sterre fix which that thou knowist,
13 17|          the ecliptik in which the sterre stondith for the tyme. For
14 17|            the sonne or of eny fix sterre, rekne hys latitude or his
15 18|              Set the centre of the sterre upon the lyne meridionall,
16 18|       there the degre in which the sterre stondith; and with that
17 18|        same degre cometh that same sterre unto that same lyne fro
18 19|            degre of the zodiak eny sterre fix in thin Astrelabie arisith
19 19|              Set the centre of the sterre upon the est orisonte, and
20 19|            degre arisith that same sterre. ~And thys merveylous arisyng
21 19|           that the latitude of the sterre fix is either north or south
22 19|           wel that neyther mone ne sterre, as in our embelif orisonte,
23 23|          wayte a tyme til that eny sterre fix sitte lyne-right perpendiculer
24 23|         pool artik, and clepe that sterre A; and wayte another sterre
25 23|        sterre A; and wayte another sterre that sitte lyne right under
26 23|           the pool, and clepe that sterre F. And understond wel that
27 24|         fro the orisonte. ~Tak eny sterre fix that never discendith
28 25|          fro the equinoxial of eny sterre fix that thou knowist, and
29 31| understonde also the cenyth of eny sterre, in which partie he riseth. ~
30 33|         thou seen by night, of eny sterre, whether the sterre sitte
31 33|            eny sterre, whether the sterre sitte est or west, or north
32 33|            the azimut in which the sterre stondith. ~
33 34|           syde the altitude of eny sterre fix which that thou knowist,
34 34|        thyn almykanteras there the sterre is founde. Wayte than which
35 34|           mone the altitude of the sterre fixe be taken. ~And nota
36 34|       sonne, as wel as by the fixe sterre. ~
37 35|            Tak the altitude of any sterre that is clepid a planete,
38 35|           anon the altitude of any sterre fix that thou knowist, and
39 35|      Awayte wel than whan that thy sterre fixe is in the same altitude
