    To me Silchester's placement looked like a repair, that is, its position between Quadrants 5 and 6 on the list and its physical location in Quadrant 3's northwest quarter fit my definition of an amendment - as a site missed during the cosmographer's inventory. But it occurs that the map's position for Calleva might have been somewhat distorted, showing it farther north than it really is in respect to a northern limit for Quadrant 3 defined by London, Staines, and Mildenhall (latitudes: 51.515, 51.432, and 51.424142N respectively;  Calleva 51.357N)).
    Given the possibility that two lines of text have been transposed, as found later in the manuscript, an emendation would neaten up things nicely. If Calleva (R&C 67) were followed by R&C 75 through R&C 78:
