they formed of Marrow and Earth, the Earth moiftned, and often dipt in Water and Fire,
Flejh is compounded* of Salt and Sharp, as of a kind of ferment. Marrow they encloled with Bones, Bones with Sinews inftead of Chains, that by thefe Inflexions the knitting of the Joints might be pliant. Over thefe as a cover IS extended the .S/l’zV, partly white, partly black, for beauty and ufe. Of thefe likewife confift the Internal Bowels, and the Belly, and the In- teftines, every where rolled about it. And from the Mouth, above the afpera Arteria,2xA the oefophagus, of which one cometh down to the Stomach, the other to the Lungs. Meat is digefted in the Belly by Spirit and Heat, and thence diftributed to the whole Body accor¬ ding to their feveral Conftitutions. The two Veins paffing along the Spine of the Back, meet, and crofs at the Head, where they fpread into many parts.
Thus when the Gods had made Man,and gi- ven him a Soul as the Miftrefs of his Body,they- placed the principal part of that Soul to which Keafon appertaineth, in the head. Whence is derived Marrow and Sinews, and by the diffe¬ rent affe£lion of this, the Mind likewife is al¬ tered. Moreover they gave him Senfes, as the /

It it bring much reft, the lleep is little difturbed with Dreams, but if there re¬ main any motions behind, we are troubled with many illufions. In this manner, Phantafies, whe¬ ther true or falfe, arife. Of the lame Nature are Images, which we fee in Glafles , or other fmooth pellucid Bodies,which exift only by le- fleGion. For, as the Glals is concave or con¬ vex, or oblopg, the objefl is differently repre- fented to the Beholder. The light being re- flefted to other parts, thofe which are di- fpeifed in convex meet in the concave, for in Ibme, the right and left fidesfeem quite invert¬ ed, mothers alike-, in others, thofe which, .are upwards feem downwards, and on the contrary, thofe which are downwards, upwards.
