Besides making corrections and additions in their copy of _O_, the scribes also insert marginal notes that have all the characteristics of the author's own amplifications of his work. This fact does not militate against our present hypothesis, if we assume that Johannes added these marginalia, or caused them to be added, in _O_, and that the scribes of _R_, at first forgetting to include them in the text of their new copy, later wrote them in the margin.[5] In some cases, as we might expect, a different ink is used. The insular hand (= _I_), which we are assuming to be that of Johannes, corrects minor errors in these enlargements now and then.[6] This fact is entirely in accord with our hypothesis. A number of enlargements omitted by the writers of the text were supplied not by them but by special correctors, who were assigned, it would seem, considerable portions of the manuscript to revise. Particularly important among these wide-ranging correctors are two hands that I will call _r^{1}_ and _r^{2}_. The former is a largish hand with some slight traces of Insular habits.[7] _r^{2}_ is very similar, and indeed may be merely a smaller variety of _r^{1}_. In the specimen that I have reproduced, as is true of both _r^{1}_ and _r^{2}_ elsewhere, correction by _I_ may be observed.[8] 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. 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.
