Chapter 4, level 4+*

“1.4+/2.4+  A number of late additions (manuscript; missing); not included in the above fair copy [level 4] but incorporated into the textual substratum of the following typescript [level 5], especially the second part.”  (JJA 46: 65)
 
There are 15 unauthorized differences between levels 4 and 5  in chapter 4, on FW: 88, 94-8, 101. Note that the assignment of a revision level to unauthorized differences at a subsequent level is unusual for the Archive, though there are many such differences elsewhere too. All such differences are accounted for in the genetics as additions at the higher level (here, level 5), marked IM, rather than being marked as level 4+.
