Manuscript copies of books by Nicole Oresme

The Cambridge manuscript

tractatus mag[nus ...] Nicholai Hor[esme]
O	mnis rationalis opinio de velocitate motuum ponit eam sequi aliquam proportionem: hec quidem proportionem excessus potentie motoris ad re- sistentiam sive potentiam rei
mote, alia vero proportionem resistentiarum manente eadem potentia vel equali, tertia potentiam motoris ad resistentiam sive potentiam rei mote, quam veram reputo eq quam

This sample too covers the opening lines of De proportionibus. For another copy of these same lines, check the Paris manuscript sample. Grant himself points out some differences relative to the Paris copy: it has "sive" instead of "seu", a whole line "vel proportionem ... equali" was skipped, "potentiam" substituted for "proportionem potentie".

Note the use of a dot for both comma, semicolon and (I presume) period. Grant describes the punctuation of such manuscripts as "chaotic," so he fixed it in the Latin transcriptions where it seemed essential.
