Note 1172 — LETTER XXXIV.
Reading edition
Their connexion by means of a ligament classes them under Synneurosis (Monro On the Bones, Dr. Kirby's edit. 29), but even this not strictly, since a common ligament connects them all. Those of the trunk, as admitting a slight degree of motion, belong to Amphiarthrosis (Anat. Compar. i. 126), and those of the abdomen, which are capable of larger movements, to Diarthrosis (Ibid. 127).
