The　first　class　of　them　as　to　violence　ends　thus：　the　second　is
  protracted　to　the　seventh　day；　the　third　to　the　eleventh；　the　fourth
  to　the　fourteenth；　the　fifth　to　the　seventeenth；　and　the　sixth　to
  the　twentieth。　Thus　these　periods　from　the　most　acute　disease　ascend
  by　fours　up　to　twenty。　But　none　of　these　can　be　truly　calculated　by
  whole　days；　for　neither　the　year　nor　the　months　can　be　numbered　by
  entire　days。　After　these　in　the　same　manner；　according　to　the　same
  progression；　the　first　period　is　of　thirty…four　days；　the　second　of
  forty　days；　and　the　third　of　sixty　days。　In　the　commencement　of
  these　it　is　very　difficult　to　determine　those　which　will　come　to　a
  crisis　after　a　long　interval；　for　these　beginnings　are　very　similar；
  but　one　should　pay　attention　from　the　first　day；　and　observe　further
  at　every　additional　tetrad；　and　then　one　cannot　miss　seeing　how　the
  disease　will　terminate。　The　constitution　of　quartans　is　agreeable　to
  the　same　order。　Those　which　will　come　to　a　crisis　in　the　shortest
  space　of　time；　are　the　easiest　to　be　judged　of；　for　the　differences　of
  them　are　greatest　from　the　commencement；　thus　those　who　are　going　to
  recover　breathe　freely；　and　do　not　suffer　pain；　they　sleep　during
  the　night；　and　have　the　other　salutary　symptoms；　whereas　those　that
  are　to　die　have　difficult　respiration；　are　delirious；　troubled　with
  insomnolency；　and　have　other　bad　symptoms。　Matters　being　thus；　one　may
  conjecture；　according　to　the　time；　and　each　additional　period　of　the
  diseases；　as　they　proceed　to　a　crisis。　And　in　women；　after
  parturition；　the　crises　proceed　agreeably　to　the　same　ratio。
  21。　Strong　and　continued　headaches　with　fever；　if　any　of　the
  deadly　symptoms　be　joined　to　them；　are　very　fatal。　But　if　without　such
  symptoms　the　pain　be　prolonged　beyond　twenty　days；　a　discharge　of
  blood　from　the　nose　or　some　abscess　in　the　inferior　parts　may　be
  anticipated；　but　while　the　pain　is　recent；　we　may　expect　in　like
  manner　a　discharge　of　blood　from　the　nose；　or　a　suppuration；
  especially　if　the　pain　be　seated　above　the　temples　and　forehead；　but
  the　hemorrhage　is　rather　to　be　looked　for　in　persons　younger　than
  thirty　years；　and　the　suppuration　in　more　elderly　persons。
  22。　Acute　pain　of　the　ear；　with　continual　and　strong　fever；　is　to　be
  dreaded；　for　there　is　danger　that　the　man　may　become　delirious　and
  die。　Since；　then；　this　is　a　hazardous　spot；　one　ought　to　pay
  particular　attention　to　all　these　symptoms　from　the　commencement。
  Younger　persons　die　of　this　disease　on　the　seventh　day；　or　still
  earlier；　but　old　persons　much　later；　for　the　fevers　and　delirium
  less　frequently　supervene　upon　them；　and　on　that　account　the　ears
  previously　come　to　a　suppuration；　but　at　these　periods　of　life；
  relapses　of　the　disease　coming　on　generally　prove　fatal。　Younger
  persons　die　before　the　ear　suppurates；　only　if　white　matter　run　from
  the　ear；　there　may　be　hope　that　a　younger　person　will　recover；
  provided　any　other　favorable　symptom　be　combined。
  23。　Ulceration　of　the　throat　with　fever；　is　a　serious　affection；　and
  if　any　other　of　the　symptoms　formerly　described　as　being　bad；　be
  present；　the　physician　ought　to　announce　that　his　patient　is　in
  danger。　Those　quinsies　are　most　dangerous；　and　most　quickly　prove
  fatal；　which　make　no　appearance　in　the　fauces；　nor　in　the　neck；　but
  occasion　very　great　pain　and　difficulty　of　breathing；　these　induce
  suffocation　on　the　first　day；　or　on　the　second；　the　third；　or　the
  fourth。　Such　as；　in　like　manner；　are　attended　with　pain；　are　swelled
  up；　and　have　redness　（erythema）　in　the　throat；　are　indeed　very
  fatal；　but　more　protracted　than　the　former；　provided　the　redness　be
  great。　Those　cases　in　which　both　the　throat　and　the　neck　are　red；
  are　more　protracted；　and　certain　persons　recover　from　them；　especially
  if　the　neck　and　breast　be　affected　with　erythema；　and　the　erysipelas
  be　not　determined　inwardly。　If　neither　the　erysipelas　disappear　on　the
  critical　day；　nor　any　abscess　form　outwardly；　nor　any　pus　be　spit
  up；　and　if　the　patient　fancy　himself　well；　and　be　free　from　pain；
  death；　or　a　relapse　of　the　erythema　is　to　be　apprehended。　It　is　much
  less　hazardous　when　the　swelling　and　redness　are　determined　outwardly；
  but　if　determined　to　the　lungs；　they　superinduce　delirium；　and
  frequently　some　of　these　cases　terminate　in　empyema。　It　is　very
  dangerous　to　cut　off　or　scarify　enlarged　uvulae　while　they　and　red　and
  large；　for　inflammations　and　hemorrhages　supervene；　but　one　should　try
  to　reduce　such　swellings　by　some　other　means　at　this　season。　When
  the　whole　of　it　is　converted　into　an　abscess；　which　is　called　Uva；
  or　when　the　extremity　of　the　variety　called　Columella　is　larger　and
  round；　but　the　upper　part　thinner；　at　this　time　it　will　be　safe　to
  operate。　But　it　will　be　better　to　open　the　bowels　gently　before
  proceeding　to　the　operation；　if　time　will　permit；　and　the　patient　be
  not　in　danger　of　being　suffocated。
  24。　When　the　fevers　cease　without　any　symptoms　of　resolution
  occurring；　and　not　on　the　critical　days；　in　such　cases　a　relapse　may
  be　anticipated。　When　any　of　the　fevers　is　protracted；　although　the　man
  exhibits　symptoms　of　recovery；　and　there　is　no　longer　pain　from　any
  inflammation；　nor　from　any　other　visible　cause；　in　such　a　case　a
  deposit；　with　swelling　and　pain；　may　be　expected　in　some　one　of　the
  joints；　and　not　improbably　in　those　below。　Such　deposits　occur　more
  readily　and　in　less　time　to　persons　under　thirty　years　of　age；　and　one
  should　immediately　suspect　the　formation　of　such　a　deposit；　if　the
  fever　be　protracted　beyond　twenty　days；　but　to　aged　persons　these　less
  seldom　happen；　and　not　until　the　fever　be　much　longer　protracted。　Such
  a　deposit　may　be　expected；　when　the　fever　is　of　a　continual　type；
  and　that　it　will　pass　into　a　quartan；　if　it　become　intermittent；　and
  its　paroxysms　come　on　in　an　irregular　manner；　and　if　in　this　form　it
  approach　autumn。　As　deposits　form　most　readily　in　persons　below　thirty
  years　of　age；　so　quartans　most　commonly　occur　to　persons　beyond　that
  age。　It　is　proper　to　know　that　deposits　occur　most　readily　in
  winter；　that　then　they　are　most　protracted；　but　are　less　given　to
  return。　Whoever；　in　a　fever　that　is　not　of　a　fatal　character；　says
  that　he　has　pain　in　his　head；　and　that　something　dark　appears　to　be
  before　his　eyes；　and　that　he　has　pain　at　the　stomach；　will　be　seized
  with　vomiting　of　bile；　but　if　rigor　also　attack　him；　and　the
  inferior　parts　of　the　hypochondrium　are　cold；　vomiting　is　still　nearer
  at　hand；　and　if　he　eat　or　drink　anything　at　such　a　season；　it　will
  be　quickly　vomited。　In　these　cases；　when　the　pain　commences　on　the
  first　day；　they　are　particularly　oppressed　on　the　fourth　and　the
  fifth；　and　they　are　relieved　on　the　seventh；　but　the　greater　part　of
  them　begin　to　have　pain　on　the　third　day；　and　are　most　especially
  tossed　on　the　fifth；　but　are　relieved　on　the　ninth　or　eleventh；　but　in
  those　who　begin　to　have　pains　on　the　fifth　day；　and　other　matters
  proceed　properly　with　them；　the　disease　comes　to　a　crisis　on　the
  fourteenth　day。　But　when　in　such　a　fever　persons　affected　with
  headache；　instead　of　having　a　dark　appearance　before　their　eyes；
  have　dimness　of　vision；　or　flashes　of　light　appear　before　their
  eyes；　and　instead　of　pain　at　the　pit　of　the　stomach；　they　have　in
  their　hypochondrium　a　fullness　stretching　either　to　the　right　or
  left　side；　without　either　pain　or　inflammation；　a　hemorrhage　from
  the　nose　is　to　be　expected　in　such　a　case；　rather　than　a　vomiting。　But
  it　is　in　young　persons　particularly　that　the　hemorrhage　is　to　be
  expected；　for　in　persons　beyond　the　age　of　thirty…five；　vomitings
  are　rather　to　be　anticipated。　Convulsions　occur　to　children　if　acute
  fever　be　present；　and　the　belly　be　they　cannot　sleep；　are　agitated；
  and　moan；　and　change　color；　and　become　green；　livid；　or　ruddy。　These
  complaints　occur　most　readily　to　children　which　are　very　young　up　to
  their　seventh　year；　older　children　and　adults　are　not　equally　liable
  to　be　seized　with　convulsions　in　fevers；　unless　some　of　the
  strongest　and　worst　symptoms　precede；　such　as　those　which　occur　in
  frenzy。　One　must　judge　of　children　as　of　others；　which　will　die　and
  which　recover；　from　the　whole　of　the　symptoms；　as　they　have　been
  specially　described。　These　things　I　say　respecting　acute　diseases；　and
  the　affections　which　spring　from　them。
  25。　He　who　would　correctly　beforehand　those　that　will　recover；　and
  those　that　will　die；　and　in　what　cases　the　disease　will　be
  protracted　for　many　days；　and　in　what　cases　for　a　shorter　time；　must
  be　able　to　form　a　judgment　from　having　made　himself　acquainted　with
  all　the　symptoms；　and　estimating　their　powers　in　comparison　with　one
  another；　as　has　been　described；　with　regard　to　the　others；　and　the
  urine　and　sputa；　as　when　the　patient　coughs　up　pus　and　pus　and　bile
  together。　One　ought　also　to　consider　promptly　the　influx　of　epidemical
  diseases　and　the　constitution　of　the　season。　One　should　likewise　be
  well　acquainted　with　the　particular　signs　and　the　other　symptoms；
  and　not　be　ignorant　how　that；　in　every　year；　and　at　every　season；
  bad　symptoms
