(Chapter 14) Footnote 4:

sic in both editions; see rather Book IV, Chapter 11 (pp. 432-33 of the 1543 edition, misnumbered 332-33, or p. 527-28 of the 1555 edition), where the spine is shown in the ventral and dorsal aspects respectively. Vesalius’ language wrongly states that the views on pp. 57 and 163-165 (1543) are repeated there separately. Each of the total of six woodcuts in fact provides a different angle of view, and those in Book IV show the spine together with its nerves. All but the first sentence of this paragraph is moved in the 1555 edition to the end of the figure legend.
