There are two cases where a small uppercase F has been written on the manuscript, once on You are not allowed to view links. Register or Login to view. and once on f103r:


Questions:

• Is the F on You are not allowed to view links. Register or Login to view. in the same ink as the illustration?  It seems hard to tell.
  
• What about the F on f103r?  Same ink as the stars and/or text?
  
• Are these two F's in the same hand?
  
• Do these two F's have anything to do with each other?  Or did two different people decide to write a small F on the manuscript for completely different reasons?
  
• Does a small uppercase F have a known meaning in other manuscripts?  Is there some reason why it might show up in these two places in the VMS?
