Note 540 — Chapter XLII
Reading edition
BN 7434, 14th century, #5, de tribus generalibus iudiciis astronomie ex quibus certa (cetera?) defluunt....
Dijon 1045 (the same, I judge, as that numbered 270 by Haskins), 15th century, fol. 172v-, “Quoniam circa tria fit omnis astronomica consideratio ... / ... sed non respiciens 3. Explicit.”
In the following MS it follows the first book of the work in four parts but is listed as distinct therefrom in the catalogue:
CUL 1693, 14th century, fols. 51-59, “Liber de tribus generalibus iudiciis astronomie ex quibus cetera omnia defluunt editus a Magistro Rogero de Herfordia. Quoniam circa tria sit (fit?) omnis astronomica consideratio ... / ... minimus vero septem horarum et 20 minutorum etc.” This last is not the same ending as in Dijon 1045, but would seem to refer to the length of the shortest day.
