There are two Muscles to each Eye-Lid, one whereof is termed the _Attollens_ or _Elevator_ and the other the _Depressor_. The Elevator takes its rise in the bottom of the Orbit of the Eye, and is fastned by a large _Aponeurosis_ to the edge of the upper Eye-Lid. The Shutter or Depressor, call'd also the _Orbicular_, hath its Origine in the great _Canthus_, or Corner of the Eye, passeth over the {24} Eye-Lid upward, and is join'd to the lesser Corner of the same Eye, being extended along its whole Compass. The Eyes have each six Muscles, _viz._ four _Recti_ and two _Obliqui_; the _Recti_ or streight Muscles are the _Elevator_, the _Depressor_, the _Adductor_, and the _Abductor_. The first of these call'd _Elevator_, or _Superbus_, draws the Eye upward, as it is pull'd downward by the _Depressor_ or _Humilis_; the _Adductor_ or _Bibitorius_ draws it toward the Nose, and the _Abductor_ or _Indignarorius_ toward the Shoulder: All these small Muscles have their Originals and Insertions in the bottom of the Orbit through which the Optick Nerve passeth, and are terminated in the Corneous Tunicle, by a very large _Tendon_. The first of the Oblique ones is term'd the _Obliquus Major_, and the other _Obliquus Minor_, because they draw the Eye obliquely. These Muscles cause Children to squint when they do not act together. The _Obliquus Minor_ is fasten'd at the outward part of the Orbit near the great Corner, and draws the Eye obliquely toward the Nose: But the _Obliquus Major_ is fixt in the inner part of the Orbit, and ascends along the Bone to the upper part of the great Corner, where its Tendon passeth thro' a small Cartilage nam'd _Trochlea_, and is inserted in the little Corner with the lesser _Obliquus Minor_, to draw the Eye obliquely toward the lesser Corner. The Ear, altho' not usually endu'd with any sensible Motion, nevertheless hath four Muscles, _viz._ one above, and three behind; the first being situated over the Temporal, and fasten'd to the Ear to draw it upward: The three others have {25} their beginning in the _Mammillary Apophysis_, and are terminated in the Root of the Ear, to draw it backward.
