§ 3. Between sections 2 and 3, a section is inserted in the late copies, which merely repeats section 1, and is clearly spurious. It does not appear at all in the best MSS.; though it is found in the black-letter editions. I quote it here from MS. L. 'TO KNOWE THE DEGRE OF THYN SONNE IN THYN ZODIAK BY THE DAYS IN THE BAKSYDE OFF THE ASTROLABYE. '[T]hanne iff þou wylte wete thatt / rekyn & knowe / qwych is the day off the monyth thatt thow arte yn_n_e, & ley thy rewle of thy astrolabye, that is to sey, the allydatha, vpon þe day in the kalendr_e_ off the Astrolabye, & he schall schewe the thy degree of the sonne.' 26, 7. After 'assendent,' the following additional paragraph occurs in MS. Bodley 619; fol. 21. It is worthy of notice, because the original of it appears in Messahala's treatise, with the title 'De noticia stellarum incognitarum positarum in astrolabio.' The paragraph runs thus:-- 'Nota. þat by þis conclusio_n_ þou may knowe also where ben at þat same tyme all_e_ oþir sterres fixed þ_a_t ben sette in thin Astrelabie, and in what place of þe firmament; And also her arising in thy orizonte, and how longe þ_a_t thei wol ben aboue þe erthe wiþ þe Arke of þe nyght / And loke eu_er_more hov many degrees þou fynde eny sterre at þat tyme sitting vpon þin Almycant_er_as, and vp-on as many degrees sette þou þe reule vpon þe altitude in þe border_e_; And by the mediaciou_n_ of þy eye through þe .2. smale holes shalt thou se þe same sterre by the same altitude aforseid, And so by this conclusiou_n_ may þou redely knowe whiche is oo sterre from a-noþ_er_ in the firmament / for as many as ben in the Astrelabie. For by þ_a_t same altitude shal thou se that same sterre, & non othir / for þ_er_e ne woll_e_ non othir altitude accorde þerto.'
