1. Abréviation de quaternion (huit feuilles, soit huit pages recto et huit pages verso).
   • Collation. —Eight 4^ns and one 5ⁿ = 74 leaves, of which the I^st and 74^th are blank.
     That is: "eight quaternions and one quinternion, which makes 74 leaves in all, of which tne first and last are blank". The language used by Blades is traditional and seems innocent: the words quaternion, quinternion, (abbreviated 4ⁿ, 5ⁿ) are the same words used in the concluding "register" of many early Italian printed books to describe the structure of those books. — (Joseph A.
