In all, I detected, or thought I detected, five or six correcting hands, which sometimes supplement stretches of text written by others, sometimes supplement their own text, and, in all the cases under discussion, add notes of the author which were evidently in the margin of O. It is sometimes hard to be sure whether r is the text-hand or not. The point is not vitally important. The main fact is that several different kinds of correcting hand make, either in their own texts or in those of others, the kind of additions or enlargements with which we are specially concerned.

It is positive that the enlargements in the manuscripts were made at the direction of the author himself. They present to the modern editor of the De Divisione Naturae the fascinating task of distinguishing the different revisions, and of following the growth of the subject in Johannes' mind. The best way, I believe, would be to print on the left-hand page the enlarged form of the text, for that is the form in which the author wished his work to be known to posterity.

However, as we have seen, we can still retain our hypothesis by supposing that I is the hand of Johannes, while r represents various correctors who copied from O enlargements added there by Johannes or at his direction.
But we have now to note an intimate connection between I and r. They collaborate on the same notes. Plate V (fol. 285v) shows us an enlargement that begins in the hand (= r3) that writes the text.
