compressing　the　lips；　and　still　more　by　using　a　tube；　you　can
  readily　draw　in　whatever　you　wish。　And　thus；　too；　the　instruments
  which　are　used　for　cupping　are　broad　below　and　gradually　become
  narrow；　and　are　so　constructed　in　order　to　suck　and　draw　in　from　the
  fleshy　parts。　The　nature　and　construction　of　the　parts　within　a　man
  are　of　a　like　nature；　the　bladder；　the　head；　the　uterus　in　woman；
  these　parts　clearly　attract；　and　are　always　filled　with　a　juice
  which　is　foreign　to　them。　Those　parts　which　are　hollow　and　expanded
  are　most　likely　to　receive　any　humidity　flowing　into　them；　but
  cannot　attract　it　in　like　manner。　Those　parts　which　are　solid　and
  round　could　not　attract　a　humidity；　nor　receive　it　when　it　flows　to
  them；　for　it　would　glide　past；　and　find　no　place　of　rest　on　them。
  But　spongy　and　rare　parts；　such　as　the　spleen；　the　lungs；　and　the
  breasts；　drink　up　especially　the　juices　around　them；　and　become
  hardened　and　enlarged　by　the　accession　of　juices。　Such　things　happen
  to　these　organs　especially。　For　it　is　not　with　the　spleen　as　with
  the　stomach；　in　which　there　is　a　liquid；　which　it　contains　and
  evacuates　every　day；　but　when　it　（the　spleen）　drinks　up　and　receives　a
  fluid　into　itself；　the　hollow　and　lax　parts　of　it　are　filled；　even　the
  small　interstices；　and；　instead　of　being　rare　and　soft；　it　becomes
  hard　and　dense；　and　it　can　neither　digest　nor　discharge　its
  contents：　these　things　it　suffers；　owing　to　the　nature　of　its
  structure。　Those　things　which　engender　flatulence　or　tormina　in　the
  body；　naturally　do　so　in　the　hollow　and　broad　parts　of　the　body；
  such　as　the　stomach　and　chest；　where　they　produce　rumbling　noises；　for
  when　they　do　not　fill　the　parts　so　as　to　be　stationary；　but　have
  changes　of　place　and　movements；　there　must　necessarily　be　noise　and
  apparent　movements　from　them。　But　such　parts　as　are　fleshy　and　soft；
  in　these　there　occur　torpor　and　obstructions；　such　as　happen　in
  apoplexy。　But　when　it　（the　flatus？）　encounters　a　broad　and　resisting
  structure；　and　rushes　against　such　a　part；　and　this　happens　when　it　is
  by　nature　not　strong　so　as　to　be　able　to　withstand　it　without
  suffering　injury；　nor　soft　and　rare；　so　as　to　receive　or　yield　to
  it；　but　tender；　juicy；　full　of　blood；　and　dense；　like　the　liver；　owing
  to　its　density　and　broadness；　it　resists　and　does　not　yield。　But
  flatus；　when　it　obtains　admission；　increases　and　becomes　stronger；　and
  rushes　toward　any　resisting　object；　but　owing　to　its　tenderness；　and
  the　quantity　of　blood　which　it　（the　liver）　contains；　it　cannot　be
  without　uneasiness；　and　for　these　reasons　the　most　acute　and
  frequent　pains　occur　in　the　region　of　it；　along　with　suppurations
  and　chronic　tumors　（phymata）。　These　symptoms　also　occur　in　the　site　of
  the　diaphragm；　but　much　less　frequently；　for　the　diaphragm　is　a　broad；
  expanded；　and　resisting　substance；　of　a　nervous　（tendinous？）　and
  strong　nature；　and　therefore　less　susceptible　of　pain；　and　yet　pains
  and　chronic　abscesses　do　occur　about　it。
  23。　There　are　both　within　and　without　the　body　many　other　kinds　of
  structure；　which　differ　much　from　one　another　as　to　sufferings　both　in
  health　and　disease；　such　as　whether　the　head　be　small　or　large；　the
  neck　slender　or　thick；　long　or　short；　the　belly　long　or　round；　the
  chest　and　ribs　broad　or　narrow；　and　many　others　besides；　all　which　you
  ought　to　be　acquainted　with；　and　their　differences；　so　that　knowing
  the　causes　of　each；　you　may　make　the　more　accurate　observations。
  24。　And；　as　has　been　formerly　stated；　one　ought　to　be　acquainted
  with　the　powers　of　juices；　and　what　action　each　of　them　has　upon
  man；　and　their　alliances　towards　one　another。　What　I　say　is　this：　if　a
  sweet　juice　change　to　another　kind；　not　from　any　admixture；　but
  because　it　has　undergone　a　mutation　within　itself；　what　does　it
  first　become？…　bitter？　salt？　austere？　or　acid？　I　think　acid。　And
  hence；　an　acid　juice　is　the　most　improper　of　all　things　that　can　be
  administered　in　cases　in　which　a　sweet　juice　is　the　most　proper。　Thus；
  if　one　should　succeed　in　his　investigations　of　external　things；　he
  would　be　the　better　able　always　to　select　the　best；　for　that　is　best
  which　is　farthest　removed　from　that　which　is　unwholesome。
