The most important symbol is that for the "sextula", which resembles very closely a cursive digit 2. Now, as stated by Friedlein, this symbol indicates the value of 1/72 of an "As". However, he stated specifically in the penultimate sentence of section 32 on page 23, the two beads in the bottom slot each have a value of 1/72. This would allow this slot to represent only 1/72 (i.e. 1/6 × 1/12 with one bead) or 1/36 (i.e. 2/6 × 1/12 = 1/3 × 1/12 with two beads) of an "uncia" respectively. This contradicts all existing documents that state this lower slot was used to count thirds of an "uncia" (i.e. 1/3 and 2/3 × 1/12 of an "As".
