(Chapter 28) Footnote 2:

In the first drawing of the articulated skeleton, the sesamoid bones marked k are identified as T and N in chapter 25 figure 1 (the hand), and w in chapter 33 figure 2 (the foot); in the second articulated skeleton, sesamoids marked k are identified as T in figure 1 of chapter 25, as w in chapter 33 figure 2, and m in figures 1 and 2. The third skeleton shows only the foot sesamoids; k in the left foot = m in chapter 33 figures 1 and 2; in the right foot, the k barely visible in the shadowing of the 1543 edition (recut in the 1555 edition) corresponds to w in chapter 33 figure 2. Other sesamoid bones are illustrated but not labeled in the fingers of the right hand, chapter 25 figure 1.
