'And lost were al, that Love _halt_ now _to-hepe_.' § 17, l. 1. principal C; tropikal AB; M _om._ The reading _tropikal_ is absurd, because there are but _two_ such; besides which, see l. 34 below. 17. the nyht (_over an erasure_) B; thee nyht (_over an erasure_) A; þe ni[gh]tes C; þe ny[gh]tes M. § 20, l. 4. figure; _here (and sometimes elsewhere) miswritten_ vig_ur_ A. Throughout the whole treatise, the scribe has commonly written 'vig_ur_'; in many places, it has been corrected to 'fig_ur_e.' § 21, l. 15. the (_before_ sterres) _supplied from_ BC. 27. where as C; wher AB. 56. ou_er_keruyd A; ou_er_kerued B; ou_er_kerueth (_the latter part of the word over an erasure_) C; _first time only_. PART II. § 2, l. 8. eu_er_ M; euere C; eu_er_y (_wrongly_) AB. § 3, ll. 31, 32. A _has_ 12 degres, _corrected to_ 18 degres; B. _has_ 12 degrees; C _has_ 18. The numbers in the MSS. in these propositions are somewhat uncertain; it seems probable that some alteration was made by Chaucer himself. The readings in MS. B give one set of calculations, which are no doubt the original ones; for in MS. A the same set is again found, but altered throughout, by the scribe who drew the diagrams. The sets of readings are these:-- Ll. 31, 32. 12 degrees B; _so in_ A, _but altered to_ 18; C _has_ 18. 37. passed 9 of the clokke the space of 10 degrees B; _so in_ A, _with_ 9 _altered to_ 8, _and_ 10 _altered to_ 2; C _has_ ij _for_ 9, _but agrees with_ A _in the reading_ 2. 39. fond ther 10 degrees of taur_us_ B; _so in_ A _originally, but_ 10 _has been corrected to_ 23, _and_ libra _is written over an erasure_. C _agrees with neither, having_ 20 _for_ 10, _but agreeing with_ A _as to_ libra. The later MSS. sometimes vary from all these. 42. an _supplied from_ C; AB _omit._ § 4, l. 5. largest C; largesse AB. 6. upon C; vn (!) AB. 8. forseide degree of his longitude] forseyde same degre of hys longitude C; forseid same gre of his longitude P; forseyde latitude his longitude (_sic!_) AB. 9. planete ys C; _miswritten_ planetes AB, _but_ is _is added in margin of_ A. 16. For '25 degrees,' all the MSS. have '15 degrees.' The mistake is probably Chaucer's own; the correction was made by Mr. Brae, who remarks that it is a mere translation from the Latin version of Ptolemy's Tetrabiblos, which has--'Signum ascendentis, quod est a _quinque_ gradibus qui super horizontem ante ipsum ascenderant usque ad _viginti quinque_ qui ad ascendentem remanserint'; Lib. iii. c. 10. In fact, it is clear that 25 must be added to 5 to make up the extent of a 'house,' which was 30 degrees. 16. ys like C; is lik P; _miswritten_ illyk AB. 17. in _is supplied from_ GM; ABC _omit it_. 23. _second_ the _supplied from_ CP; AB _omit_. 32. wel _supplied from_ CPM; AB _omit_. 36. than] þan CM; þenne P; AB _omit_. 40. _The number_ 10 _is supplied from_ C; AB _omit_. 42. some folk _supplied from_ CPG; AB _omit_. 44. yit is] AB _wrongly have_ yit it is; _but_ CPGM _omit_ it.
