Insert of words, lines, paragraphs.

I think these properties of the text have something to do with the way it was copied.  It seems that the scribe laid down certain portions of the text here and there first, to "anchor" it I suppose, in order to give himself a sort of guideline, and then filled in the rest.  I assume he did this because he knew it would be difficult to squeeze all the text in and he wanted to make sure that he didn't run out of space without having copied all the text that was supposed to go on that page.

It seems to be the pages with lots of text and little extra space (Bio and Stars sections) where we see evidence of text laid down in multiple passes, and not so much the pages with lots of blank space, such as in the Herbal sections.
