Misline

If the addition was in verse, he might set it up as prose or misline it, placing perhaps too many or too few feet in a line and thus throwing out the whole arrangement of the verse.

The author apparently mislined his verse here, as both texts place the words at the end of l. 60 but correctly end l. 61 with 'weepe'

Both compositors had some difficulty with lineation, but X mislined his copy only eight times whereas Y mislined his stint twenty-two times, often in more serious ways.
