This Membranous part, as all other Membranes, is made of seede. In a Man it is vnder the fat, but in Apes, Dogges, Sheepe, and such like, it lyeth immediately vnder the skin. It compasseth the whole body, and closely cleaueth to the skin by the mediation of manie Veynes, but fewer Nerues and Arteries diuersly propagated, and through it climbing vp thither, whereto also helpe the addition of fleshy Fibres. It cleaueth also to the Mem∣branes of the Muscles vnder it, but by more slender Fibres. It is saide by some to haue his Originall from the backe, because it cleaueth thereto most inseparably, and there resem∣bleth the other Membranes; but where it toucheth the arme holes, it becommeth in dogs and Apes very fleshy, Galen saith musculous.
In Infants it resembleth Flesh altogether, because of the aboundance of blood wherein it is steeped; in grown bodies by reason of continuall exiccation, it becommeth like a mem∣brane, yet so, that in the fore-part of the necke and in the forehead, it cleaueth to it so fast with his fleshy Fibres, that it can ••neath be separated, and to the broad Muscle, that it is thought to giue him his body. It is in a man except the forehead immooueable; in beasts it is not onely mooueable it selfe, but also maketh the skinne mooueable especially in the necke, by shaking whereof they driue away the Flies, but a horse in shaking of his skin, will sometime shake an vnskilfull rider out of his seate. In the inner part which is next to the membrane of the Muscles, this fleshy panicle by reason of a slimy moisture wherewith al∣most all Membranes are couered, it is slippery, that it may not hinder the motion of the Muscles, and it hath an exquisite sense, so that if it be goaded by any sharpe humor, it cau∣seth a rigor or shiuering. The vses of this Membrane are: To compasse the whole bodie, to couer and defend it: To hinder the fat from being melted by the continuall motion of the Muscles. It supporteth also saith Galen, 3. Amintstrat. Anat. 2. the vessels which attaine vnto the skin, because there passe betweene it and this Membrane, not onely many Capil∣larie and threddy Veines, but also those which wee vse to diuide in bloud-letting, together with many Arteries and Sinnewes. Finally, it helpeth to consolidate or heale vp the skin when it is wounded, or otherwise violated; for without flesh it cannot revnite, so saith Ari∣stotle in his third Booke de Historia Animalium, 11. Wheresoeuer the skin is without Flesh, there it cannot revnite being diuided. In brute Beasts, the thickenesse and fastnesse of this Membrane, reteyneth the bloody vapors, and turneth them into good blood, and besides it maketh their skins mooueable. And thus much of the Common Containing or Inve∣sting parts. But because we made mention euen now of the Veines which run betweene the skin & the fleshy Membrane which are vsually many of them opened in Phlebotomy; and for that young Chirurgions had neede be betimes acquainted with them, we haue on the former side of the leafe added two Tables and their expositions at large, by which hee that listeth may in one view see all the branches of the skin veines how they are seated, and beside learne to call them by their names, that when he is commanded, he may know how to buckle himselfe to his businesse.
