  The leaves (124 in number) are ruled throughout in a slightly reddish ink, both for margins and for writing lines; most pages show dots for guidance in ruling the margins, and many show the same dots along the right-hand side of the recto of the leaf for guidance in the ruling of the writing lines. There are four ruled but unused leaves at the back of the text block.
  
  
  
  The leaves are approximately 16.8 by 11.8 centimeters in size.
  
  As a rule the number of written lines to a page varies between twenty-four (sixty-nine examples) and twenty-five (one hundred sixty-two examples); there are also pages with twenty-two lines (three examples), 23 (3 examples), 26 (7 examples), 27 (1 example, and 2 (the final page of each of the two included works), with 18 lines.
