this　white…lead；　processes　of　stirring；　separating；　washing；
  grinding；　rolling；　and　pressing　succeed。　　Some　of　these　are
  unquestionably　inimical　to　health；　the　danger　arising　from
  inhalation　of　particles　of　lead；　or　from　contact　between　the　lead
  and　the　touch；　or　both。　　Against　these　dangers；　I　found　good
  respirators　provided　（simply　made　of　flannel　and　muslin；　so　as　to
  be　inexpensively　renewed；　and　in　some　instances　washed　with　scented
  soap）；　and　gauntlet　gloves；　and　loose　gowns。　　Everywhere；　there　was
  as　much　fresh　air　as　windows；　well　placed　and　opened；　could
  possibly　admit。　　And　it　was　explained　that　the　precaution　of
  frequently　changing　the　women　employed　in　the　worst　parts　of　the
  work　（a　precaution　originating　in　their　own　experience　or
  apprehension　of　its　ill　effects）　was　found　salutary。　　They　had　a
  mysterious　and　singular　appearance；　with　the　mouth　and　nose
  covered；　and　the　loose　gown　on；　and　yet　bore　out　the　simile　of　the
  old　Turk　and　the　seraglio　all　the　better　for　the　disguise。
  At　last　this　vexed　white…lead；　having　been　buried　and　resuscitated；
  and　heated　and　cooled　and　stirred；　and　separated　and　washed　and
  ground；　and　rolled　and　pressed；　is　subjected　to　the　action　of
  intense　fiery　heat。　　A　row　of　women；　dressed　as　above　described；
  stood；　let　us　say；　in　a　large　stone　bakehouse；　passing　on　the
  baking…dishes　as　they　were　given　out　by　the　cooks；　from　hand　to
  hand；　into　the　ovens。　　The　oven；　or　stove；　cold　as　yet；　looked　as
  high　as　an　ordinary　house；　and　was　full　of　men　and　women　on
  temporary　footholds；　briskly　passing　up　and　stowing　away　the
  dishes。　　The　door　of　another　oven；　or　stove；　about　to　be　cooled　and
  emptied；　was　opened　from　above；　for　the　uncommercial　countenance　to
  peer　down　into。　　The　uncommercial　countenance　withdrew　itself；　with
  expedition　and　a　sense　of　suffocation；　from　the　dull…glowing　heat
  and　the　overpowering　smell。　　On　the　whole；　perhaps　the　going　into
  these　stoves　to　work；　when　they　are　freshly　opened；　may　be　the
  worst　part　of　the　occupation。
  But　I　made　it　out　to　be　indubitable　that　the　owners　of　these　lead…
  mills　honestly　and　sedulously　try　to　reduce　the　dangers　of　the
  occupation　to　the　lowest　point。
  A　washing…place　is　provided　for　the　women　（I　thought　there　might
  have　been　more　towels）；　and　a　room　in　which　they　hang　their
  clothes；　and　take　their　meals；　and　where　they　have　a　good　fire…
  range　and　fire；　and　a　female　attendant　to　help　them；　and　to　watch
  that　they　do　not　neglect　the　cleansing　of　their　hands　before
  touching　their　food。　　An　experienced　medical　attendant　is　provided
  for　them；　and　any　premonitory　symptoms　of　lead…poisoning　are
  carefully　treated。　　Their　teapots　and　such　things　were　set　out　on
  tables　ready　for　their　afternoon　meal；　when　I　saw　their　room；　and
  it　had　a　homely　look。　　It　is　found　that　they　bear　the　work　much
  better　than　men：　　some　few　of　them　have　been　at　it　for　years；　and
  the　great　majority　of　those　I　observed　were　strong　and　active。　　On
  the　other　hand；　it　should　be　remembered　that　most　of　them　are　very
  capricious　and　irregular　in　their　attendance。
  American　inventiveness　would　seem　to　indicate　that　before　very　long
  white…lead　may　be　made　entirely　by　machinery。　　The　sooner；　the
  better。　　In　the　meantime；　I　parted　from　my　two　frank　conductors
  over　the　mills；　by　telling　them　that　they　had　nothing　there　to　be
  concealed；　and　nothing　to　be　blamed　for。　　As　to　the　rest；　the
  philosophy　of　the　matter　of　lead…poisoning　and　workpeople　seems　to
  me　to　have　been　pretty　fairly　summed　up　by　the　Irishwoman　whom　I
  quoted　in　my　former　paper：　　'Some　of　them　gets　lead…pisoned　soon；
  and　some　of　them　gets　lead…pisoned　later；　and　some；　but　not　many；
  niver；　and　'tis　all　according　to　the　constitooshun；　sur；　and　some
  constitooshuns　is　strong　and　some　is　weak。'　　Retracing　my　footsteps
  over　my　beat；　I　went　off　duty。
  CHAPTER　XXXVI　…　A　FLY…LEAF　IN　A　LIFE
  Once　upon　a　time　（no　matter　when）；　I　was　engaged　in　a　pursuit　（no
  matter　what）；　which　could　be　transacted　by　myself　alone；　in　which　I
  could　have　no　help；　which　imposed　a　constant　strain　on　the
  attention；　memory；　observation；　and　physical　powers；　and　which
  involved　an　almost　fabulous　amount　of　change　of　place　and　rapid
  railway　travelling。　　I　had　followed　this　pursuit　through　an
  exceptionally　trying　winter　in　an　always　trying　climate；　and　had
  resumed　it　in　England　after　but　a　brief　repose。　　Thus　it　came　to　be
  prolonged　until；　at　length　…　and；　as　it　seemed；　all　of　a　sudden　…
  it　so　wore　me　out　that　I　could　not　rely；　with　my　usual　cheerful
  confidence；　upon　myself　to　achieve　the　constantly　recurring　task；
  and　began　to　feel　（for　the　first　time　in　my　life）　giddy；　jarred；
  shaken；　faint；　uncertain　of　voice　and　sight　and　tread　and　touch；
  and　dull　of　spirit。　　The　medical　advice　I　sought　within　a　few
  hours；　was　given　in　two　words：　　'instant　rest。'　　Being　accustomed
  to　observe　myself　as　curiously　as　if　I　were　another　man；　and
  knowing　the　advice　to　meet　my　only　need；　I　instantly　halted　in　the
  pursuit　of　which　I　speak；　and　rested。
  My　intention　was；　to　interpose；　as　it　were；　a　fly…leaf　in　the　book
  of　my　life；　in　which　nothing　should　be　written　from　without　for　a
  brief　season　of　a　few　weeks。　　But　some　very　singular　experiences
  recorded　themselves　on　this　same　fly…leaf；　and　I　am　going　to　relate
  them　literally。　　I　repeat　the　word：　　literally。
  My　first　odd　experience　was　of　the　remarkable　coincidence　between
  my　case；　in　the　general　mind；　and　one　Mr。　Merdle's　as　I　find　it
  recorded　in　a　work　of　fiction　called　LITTLE　DORRIT。　　To　be　sure；
  Mr。　Merdle　was　a　swindler；　forger；　and　thief；　and　my　calling　had
  been　of　a　less　harmful　（and　less　remunerative）　nature；　but　it　was
  all　one　for　that。
  Here　is　Mr。　Merdle's　case：
  'At　first；　he　was　dead　of　all　the　diseases　that　ever　were　known；
  and　of　several　bran…new　maladies　invented　with　the　speed　of　Light
  to　meet　the　demand　of　the　occasion。　　He　had　concealed　a　dropsy　from
  infancy；　he　had　inherited　a　large　estate　of　water　on　the　chest　from
  his　grandfather；　he　had　had　an　operation　performed　upon　him　every
  morning　of　his　life　for　eighteen　years；　he　had　been　subject　to　the
  explosion　of　important　veins　in　his　body　after　the　manner　of
  fireworks；　he　had　had　something　the　matter　with　his　lungs；　he　had
  had　something　the　matter　with　his　heart；　he　had　had　something　the
  matter　with　his　brain。　　Five　hundred　people　who　sat　down　to
  breakfast　entirely　uninformed　on　the　whole　subject；　believed　before
  they　had　done　breakfast；　that　they　privately　and　personally　knew
  Physician　to　have　said　to　Mr。　Merdle；　〃You　must　expect　to　go　out；
  some　day；　like　the　snuff　of　a　candle；〃　and　that　they　knew　Mr。
  Merdle　to　have　said　to　Physician；　〃A　man　can　die　but　once。〃　　By
  about　eleven　o'clock　in　the　forenoon；　something　the　matter　with　the
  brain；　became　the　favourite　theory　against　the　field；　and　by　twelve
  the　something　had　been　distinctly　ascertained　to　be　〃Pressure。〃
  'Pressure　was　so　entirely　satisfactory　to　the　public　mind；　and
  seemed　to　make　every　one　so　comfortable；　that　it　might　have　lasted
  all　day　but　for　Bar's　having　taken　the　real　state　of　the　case　into
  Court　at　half…past　nine。　　Pressure；　however；　so　far　from　being
  overthrown　by　the　discovery；　became　a　greater　favourite　than　ever。
  There　was　a　general　moralising　upon　Pressure；　in　every　street。　　All
  the　people　who　had　tried　to　make　money　and　had　not　been　able　to　do
  it；　said；　There　you　were！　　You　no　sooner　began　to　devote　yourself
  to　the　pursuit　of　wealth；　than　you　got　Pressure。　　The　idle　people
  improved　the　occasion　in　a　similar　manner。　　See；　said　they；　what
  you　brought　yourself　to　by　work；　work；　work！　　You　persisted　in
  working；　you　overdid　it；　Pressure　came　on；　and　you　were　done　for！
  This　consideration　was　very　potent　in　many　quarters；　but　nowhere
  more　so　than　among　the　young　clerks　and　partners　who　had　never　been
  in　the　slightest　danger　of　overdoing　it。　　These；　one　and　all
  declared；　quite　piously；　that　they　hoped　they　would　never　forget
  the　warning　as　long　as　they　lived；　and　that　their　conduct　might　be
  so　regulated　as　to　keep　off　Pressure；　and　preserve　them；　a　comfort
  to　their　friends；　for　many　years。'
  Just　my　case　…　if　I　had　only　known　it　…　when　I　was　quietly　basking
  in　the　sunshine　in　my　Kentish　meadow！
  But　while　I　so　rested；　thankfully　recovering　every　hour；　I　had
  experiences　more　odd　than　this。　　I　had　experiences　of　spiritual
  conceit；　for　which；　as　giving　me　a　new　warning　against　that　curse
  of　mankind；　I　shall　always　feel　grateful　to　the　supposition　that　I
  was　too　far　gone　to　protest　against　playing　sick　lion　to　any　stray
  donkey　with　an　itching　hoof。　　All　sorts　of　people　seemed　to　become
  vicariously　religious　at　my　expense。　　I　received　the　most
  uncompromising　warning　that　I　was　a　Heathen：　　on　the　conclusive
  authority　of　a　field　preacher；　who；　like　the　most　of　his　ignorant
  and　vain　and　daring　class；　could　not　construct　a　tolerable　sentence
  in　his　native
