I found another "poxleber"

[npcompl33t]

I searched through my own reference corpus for some of these terms.

Forgive me if this is already known, it can sometimes be difficult to keep up with everything discovered on the forum here. The curated thread says x is uncommon in medieval German manuscripts, but it seems it was not to unusual for it to appear in place of the consonant sequence /ks/, i have over 50 such occurrences in my own reference materials, spanning across Germany: 

• “kertzen von wax gemacht”  Begencknus: Kayserlicher Maiestat, 1493, Middle Bavarian. Line 91 
  
• “an diſem wexel” Maria Magdalena verse legend, first half of the 14th century, South Bavarian. Line 1647 
  
• “hie wrden gewexelt zaͤher gᵒzez” Same manuscript. Line 1659
  
• “linx odˢ rechtz” — left or right. 1497 Cirurgia, line 419
  
• “das er nit flux mer drincken mag”. Reimpaarsprüche, line 744
  
• “off vmme hat em daghelix afkeren”. Dat myrren bund., line 1443
  
  

( line numbers are in reference to the transcription) 
So packs leber, pokchleber, pokch leber written as pox leber doesn't seem far fetched.

I also found an instance of milch being written as miˡch, 

chrut. vn̄ ſivͦt ez in geizíner
miˡch. mit ſwinē ſmalz. vn̄

This is in You are not allowed to view links. Register or Login to view., Cgm 92, folio 16r, right-hand column (b), line 17. 16rb,17 in the transcription., 2nd half of 13th century. The document mentions milk multiple times, however most of the time they are written as milch, without the raised l.  

The same document has multiple psuedo-Latin appearing, mostly as charms to be written. 

• ON. ON. ON. inclimus milus 
  
• Rex. pax. nax. in Christo filio 
  

inclimus milus doesn't seem to have any valid latin reading i can discern, and this line actually just a few lines below the miˡch occurence.
