glyph [d] as a substitute for [p] and [f]

[Emma May Smith]

A few thoughts:

• [d] is common on the first line of a paragraph, which would need to be explained.
  
• [p, f] are shorter when written away from the first line of paragraphs and [k, t] are taller when written on the first line. The scribe was capable of adjusting the glyph height.
  
• [d, l, r, s] all lack significant number of [e] following them.
  
• [p, f] take relatively good numbers of [ch, sh] following them, which [d] does not, especially away from the start of the line.
