ber 27. and made by Fracassati and Malpighi; for it is contain'd in an Execitation De Omento, annexed to the Tetras Anatomicarum Epistolarum Marcelli Malpighii and Caroli Fracassati de Lingua & Cerebro, printed in Bononia. Since it was then omitted, it was thought worth the inserting now, viz.
The Epiploon, being look'd upon by a good Microscope, is like a great Sack full of abundance of other small Sacks, which do inclose gatherings of Grease or Fat. There are many Vessels which may be call'd Adipous or Fatty, which issue out of this Membrane, and spreading themselves all over the Body, conveigh Fat to it, just as the Arteries carry the Blood all over the same. Whereever is Fat or Grease, there is found store of these little Sacks, wherein that is inclosed; whence it is, that in lean and emaciated Bodies, instead of Fat, you find nothing but Skins.
