    Inserted into the posterior surface of the Manubrium Mallei below its Processus Brevis. 3. Internus Manubrii Mallet Arises by a very small beginning from the posterior cartilaginous extremity of the Eustachian Tube, and broad and fleshy from the Sinus Muscularis. The fleshy fibres from these origins terminate in a slender round tendon, which runs directly outwards from the sharp osseous ridge at the termination of the anterior extremity of the Pro- cessus Fallopii, and is Inserted into the inner surface of the Manubrium Mal- lei behind but a little below its Processus Brevis. 4. Anterior Capitis Mallet Arises from that part of the outer surface of the Fossa Navicularis just before the head of the Malleus, and from thence runs obliquely backwards and inwards about the twelfth part of an inch, and is Inserted into the depression in the anterior surface of the head of the Malleus. 5. Superior Capitis Mallei* Arises fleshy from that part of the superior surface of the Fossa Navicularis just above the head of the Malleus, where it is articulated with the body of the Incus, and from thence descends, and is Inserted tendinous into the superior and inner part of the head of the Malleus, close to the margin of the articu- lating surface. 6. Obliquus Incudis Externus Posterior Arises fleshy from the external surface of the Fossa Na- vicularis just before the beginning of the Mastoid Cells, and from thence descends obliquely forwards and inwards, and is * This muscle is described by Scemmerring as a ligament. He calls it Ligamentum Proprium Teres.—S@MMERRING, Icones, Organi Auditus Humani, tab. ii. fig. 20.
