XXXIV. A Wound in the Fore∣head, near the Eye-brows, if long∣ways, according to the Course of the Fibres, when healed, will not hurt the Function of the Part, or Eye-lid; but if it be transverse and deep, the Eye-brow and Skin un∣der it will be drawn downwards, causing a great trouble to the Eyes, because the upper Eye-lid cannot open freely, nor perfectly do its Duty. This Substance lying up∣on the Forehead, and sticking fast to it, Galen calls a Musculous Skin; Vesalius, not a Musculous, but a Carnous Membrane, but Fallopius says, it is perfect Mus∣cle, from its Fibres and Motion; and Realdus, that it is duplicate, because he has seen one side of the Forehead convulst, whilst the sound side was entire in its Function. These Muscles have no Tendon, because it is not a Bone, but a Skin that is to be moved, and is terminated in that common Suture, which di∣vides the Bones of the Head from those of the upper Jaw: And their Fibres (as Vesalius says) run in a direct Line from the top of the Nose to the begin∣ning of the Forehead; but Co∣lumous says, they run obliquely, from the top of the Nose, to the said middle of the Fore∣head.
XXXV. If the upper Eye-lid is wounded transverse, in the space between the Corners of the Eye, the total loss of the Function of the Eye-lid follows, if the Wound be deep; but if not deep, it will only not shut close. For in this Case, the two oblique Muscles moving and lifting up the Eye-lid, must be cut asunder, or much hurt, according to the Effect following.
