"Of the Muscles of the Tongue.
For the Motion of this Part, Authors assign various Numbers of Muscles; some reckoning eight, others nine, some ten, and others eleven, amongst which they count the Tongue it self" (Cowper, 1724, Chap. XIV).
"Of the Muscles of the Os Hyoides, or Bone of the Tongue.
Since the Os Hyoides is fastened to the Tongue and Larynx, the Muscles which move it ought to be esteemed common to both" (Cowper, 1724, Chap. X111).
