[542] As we have already seen to be the case in CUL 1693, fols. 40-51-59. In Selden supra 76, the work in four parts begins at fol. 3r, “Liber magistri Rogeri Hereford de iudiciis astronomicis. Quoniam regulas artis....” At fol. 10v, Liber de tribus generalibus iudiciis astronomie ex quibus cetera omnia defluunt, editus a magistro Rogero Hereford. In three books and a prologue, opening, “Quoniam circa tria fit omnis astronomica consideracio....” The question then arises, do fol. 14v, “Incipit liber secundus de cogitatione. Sed quum iam de intentione et cogitatione tractandum...”; and fol. 18r, “Incipit liber tercius de electione vel operatione per quod fiat electio”; have reference to the last two books of _Three General Judgments_ or to the two middle books of the work in four parts? Apparently the former, since there is no fourth part given; at fol. 20 seems to open another treatise, _Liber de motibus planetarum_. MS E Musaeo 181 has the same arrangement as Selden supra 76, fols. 10-18, but ends with the second book _De cogitacione_. For the first of the four parts it is fuller than Selden supra 76, fols. 3-9. Laud. Misc. 594, fols. 136-137r, beginning mutilated, opens “illius signi et duodenarie ostendentis” and ends “secunda si vero respiciens tertia. Explicit liber de quatuor partibus iudiciorum astronomiae editus a magistro Rogero de Hereford.” But the closing words, “respiciens tertia,” are those connected with the Incipit of the _Book of Three General Judgments_ in Dijon 1045, a good illustration of the complexities of the problem. [543] Besides the fly-leaf of Royal 12-F-17, mentioned above in a note, Ashmole 192, #2, pp. 1-17, “Expliciunt iudicia Herfordensis multum bona et utilia.” It will be noted that in Selden supra 76 the title _De iudiciis_ is applied to the work in four parts. [544] Neither name, for example, despite the devotion of both to astrology, appears in the index of T. O. Wedel’s, _The Mediaeval Attitude toward Astrology particularly in England_, Yale University Press, 1920. [545] For example, in the same MS with Daniel of Morley’s work, Arundel 377, fol. 86v, de altitudine Solis etc. apud Toletum et Herefordiam; _Ibid._, “Anni collecti omnium planetarum compositi a magistro Rogero super annos domini ad mediam noctem Herefordie anno ab incarnatione domini mclxxviii post eclipsim que contigit Hereford eodem anno” (13 September).
