(Chapter 6) Footnote 133:

Modern anatomy distinguishes two types of unindented suture: the sutura squamosa where contiguous bones are overlapped by a broad bevelled margin (e.g., between the temporal and parietal bones), and the sutura plana or harmonia where contiguous rough surfaces meet in a simple apposition, as in the articulation between the maxillae or the horizontal plates of the palatine bones. See Gray 1985, p. 332. In this passage, we translate Vesalius’ conglutinationes “cohesive joints.”
