Now then there follow the proportions of augmentation, of course, the sub-duple, sub-triple, and sub-quadruple. These then can all be comprehended under one rule, that within each proportion, all the notes and rests are augmented by whatever time the numerator is contained in the denominator, in the following manner: in sub-duple, everything is doubled; in sub-triple, everything is tripled; and in sub-quadruple, everything is quadrupled.
I assumed that in asking for a transcription, the questioner was seeking something like a more standard form of modern notation without extensive use of breves and longae, which required exactly that level of reduction. Here are the original note values, first with G clef and slurs, then with C clef and no slurs.I do want to ask why you chose four-to-one reduction, which I think makes this more confusing.
