At fol. 21 is an additional section, not found elsewhere, which is printed in the Notes; see p. 360. This Conclusion has some claims to our notice, because, whether genuine or not, it is translated from Messahala. § 7. F.--MS. 424, in the Library of Corpus Christi College, Cambridge. Very imperfect, especially at the beginning, where a large portion has been lost. The Conclusions follow the right order, as in the best MSS. § 8. G.--MS. R. 15, 18, in the Library of Trinity College, Cambridge. This is a curious and interesting volume, as it contains several tracts in English on astrology and astronomy, with tables of stars, &c. The copy of the 'Astrolabe' in this MS. is not a good one. It ends in Part ii. sect. 34, l. 14. The Conclusions are in the right order, and there are a few diagrams. § 9. H.--MS. Sloane 314, British Museum. A late MS. on paper, absurdly said in a note to be in Chaucer's handwriting, whereas it is clearly to be referred to the end of the fifteenth century. § 10. I.--MS. Sloane 261. This is an 'edited' MS., having been apparently prepared with a view to publication. Mr. Brae has made considerable use of it, and gives, in his preface, a careful and interesting account of it. He concludes that this MS. was written by Walter Stevins in 1555, and dedicated by him to Edward Earl of Devonshire; and that MS. H. was one of those which Stevins especially consulted, because it contains marginal notes in Stevins' handwriting. The contents of this MS. can be so well ascertained from Mr. Brae's edition that it is unnecessary to say more about it here. The Conclusions are arranged in the same order as in other MSS. that are _not_ of the first class. § 11. K.--MS. Rawlinson Misc. 3, in the Bodleian Library, Oxford. On vellum, 49 folios, with rich gold capitals, beautifully ornamented; in a large clear handwriting, with red rubrics. Title--'Astralabium.' Begins--'Lityl lowys my sone,' &c.--and ends--'For þe mone meuyth the contrarie from other planetys. as yn here epicircle. but in none other maner'; see end of Part ii. sect. 35; p. 217. Order of Conclusions in Part ii. as follows; 1-12, 19-21, 13-18, 22-35; as in other late MSS. There are no diagrams, and the MS., though well written, may perhaps be referred to the latter half of the fifteenth century. § 12. L.--MS. Additional 23002, British Museum. A fair MS., on vellum, without diagrams; imperfect. See description of MS. R. in § 17. And see the Note on Part ii. sect. 3 (p. 360).
