The Parts contain'd in the _Epigastrium_ are the Liver, the Spleen, the Stomach, and the _Pancreas_ or Sweet-bread, which lies underneath: The Stomach takes up the middle before, the Liver being plac'd on the Right side, and the Spleen on the Left; so that these two sides of the Epigastrick Region, are call'd the Right and Left _Hypochondria_. _What Parts are there contain'd in the Umbilical Region, and what is their situation?_ They are the most part of the thin Intestines or small Guts, _viz._ the _Duodenum_, the _Jejunum_, and the _Ileon_, which have their Residence in the middle, where they are encircled with a Portion of the two great Guts, _Cæcum_ and _Colon_, that take possession of the Sides, otherwise call'd the Flanks. The Reins or Kidneys are also in this Place, above, and somewhat backward. _What Parts are there contain'd in the _Hypogastrium_, and of what Place are they possest?_ The greater part of the thick-Guts, _Coecum_, and _Colon_, are enclos'd therein, with the entire _Rectum_; there is also a Portion of the _Ileon_, which hides it self in the sides of the _Ilia_, or Hip-Bones: In the middle under the _Os Pubis_, the Bladder is situated on the Gut _Rectum_ in Men, and the _Matrix_ in Women lies between the _Rectum_ and Bladder. _After what manner is the opening of a Corps or dead Body perform'd at a publick Dissection?_ {68} It is begun with a Crucial Incision in the Skin from underneath the Throat downward, traversing from one side to another in the Umbilical Region; then this Skin is pull'd off at the four Corners, and the _Panicula Adiposa_ is immediately discover'd: Under this Fat lies a Fleshy Membrane, call'd _Membrana Carnosa_; and after that, the common Membrane of all the Muscles of the lower Belly. Thus we have taken a View of what Anatomists commonly term the _five Teguments_, that is to say, the _Epiderma_ or Scarf-Skin, the _Derma_ or true Skin, the _Panicula Adiposa_, the _Panicula Carnosa_ or _Membranus Carnosa_, and the common Membrane of the Muscles. The five Teguments being remov'd, we meet with as many Muscles on each side, _viz._ the descending Oblique, the ascending Oblique, the Transverse, the streight, and the Pyramidal, by the means whereof the Belly is extended and contracted. Afterwards appears a Membrane nam'd _Peritonæum_, which contains all the Bowels, and covers the whole lower Belly, being strongly fasten'd to the first and third _Vertebra's_ of the Back. The Fat skinny Net which lies immediately under the _Peritonæum_, is call'd _Epiploon_ and _Omentum_, or the Caul; it floats over the Bowels, keeping them in a continual Suppleness necessary for their Functions, maintains the Heat of the Stomach, and contributes to Digestion.
