  with　others。　　Equally　so　with　the　inhabitants　of　the　atmosphere：
  some　of　surpassing　wisdom；　some　of　horrible　malignity；　some
  hostile　as　fiends　to　men；　others　gentle　as　messengers　between
  earth　and　heaven。
  He　who　would　establish　intercourse　with　these　varying　beings
  resembles　the　traveller　who　would　penetrate　into　unknown　lands。
  He　is　exposed　to　strange　dangers　and　unconjectured　terrors。　　THAT
  INTERCOURSE　ONCE　GAINED；　I　CANNOT　SECURE　THEE　FROM　THE　CHANCES　TO
  WHICH　THY　JOURNEY　IS　EXPOSED。　　I　cannot　direct　thee　to　paths　free
  from　the　wanderings　of　the　deadliest　foes。　　Thou　must　alone；　and
  of　thyself；　face　and　hazard　all。　　But　if　thou　art　so　enamoured　of
  life　as　to　care　only　to　live　on；　no　matter　for　what　ends；
  recruiting　the　nerves　and　veins　with　the　alchemist's　vivifying
  elixir；　why　seek　these　dangers　from　the　intermediate　tribes？
  Because　the　very　elixir　that　pours　a　more　glorious　life　into　the
  frame；　so　sharpens　the　senses　that　those　larvae　of　the　air　become
  to　thee　audible　and　apparent；　so　that；　unless　trained　by　degrees
  to　endure　the　phantoms　and　subdue　their　malice；　a　life　thus
  gifted　would　be　the　most　awful　doom　man　could　bring　upon　himself。
  Hence　it　is；　that　though　the　elixir　be　compounded　of　the　simplest
  herbs；　his　frame　only　is　prepared　to　receive　it　who　has　gone
  through　the　subtlest　trials。　　Nay；　some；　scared　and　daunted　into
  the　most　intolerable　horror　by　the　sights　that　burst　upon　their
  eyes　at　the　first　draft；　have　found　the　potion　less　powerful　to
  save　than　the　agony　and　travail　of　Nature　to　destroy。　　To　the
  unprepared　the　elixir　is　thus　but　the　deadliest　poison。　　Amidst
  the　dwellers　of　the　threshold　is　ONE；　too；　surpassing　in

  〃Nay；　thy　words　but　kindle　it。〃
  〃Follow　me；　then；　and　submit　to　the　initiatory　labours。〃
  With　that；　Mejnour　led　him　into　the　interior　chamber；　and
  proceeded　to　explain　to　him　certain　chemical　operations　which；
  though　extremely　simple　in　themselves；　Glyndon　soon　perceived
  were　capable　of　very　extraordinary　results。
  〃In　the　remoter　times；〃　said　Mejnour；　smiling；　〃our　brotherhood
  were　often　compelled　to　recur　to　delusions　to　protect　realities；
  and；　as　dexterous　mechanicians　or　expert　chemists；　they　obtained
  the　name　of　sorcerers。　　Observe　how　easy　to　construct　is　the
  Spectre　Lion　that　attended　the　renowned　Leonardo　da　Vinci！〃
  And　Glyndon　beheld　with　delighted　surprise　the　simple　means　by
  which　the　wildest　cheats　of　the　imagination　can　be　formed。　　The
  magical　landscapes　in　which　Baptista　Porta　rejoiced；　the　apparent
  change　of　the　seasons　with　which　Albertus　Magnus　startled　the
  Earl　of　Holland；　nay；　even　those　more　dread　delusions　of　the
  Ghost　and　Image　with　which　the　necromancers　of　Heraclea　woke　the
  conscience　of　the　conqueror　of　Plataea　（Pausanias；see
  Plutarch。）；all　these；　as　the　showman　enchants　some　trembling
  children　on　a　Christmas　Eve　with　his　lantern　and　phantasmagoria；
  Mejnour　exhibited　to　his　pupil。
  。。。
  〃And　now　laugh　forever　at　magic！　when　these；　the　very　tricks；　the
  very　sports　and　frivolities　of　science；　were　the　very　acts　which
  men　viewed　with　abhorrence；　and　inquisitors　and　kings　rewarded
  with　the　rack　and　the　stake。〃
  〃But　the　alchemist's　transmutation　of　metals〃
  〃Nature　herself　is　a　laboratory　in　which　metals；　and　all
  elements；　are　forever　at　change。　　Easy　to　make　gold；easier；
  more　commodious；　and　cheaper　still；　to　make　the　pearl；　the
  diamond；　and　the　ruby。　　Oh；　yes；　wise　men　found　sorcery　in　this
  too；　but　they　found　no　sorcery　in　the　discovery　that　by　the
  simplest　combination　of　things　of　every…day　use　they　could　raise
  a　devil　that　would　sweep　away　thousands　of　their　kind　by　the
  breath　of　consuming　fire。　　Discover　what　will　destroy　life；　and
  you　are　a　great　man！what　will　prolong　it；　and　you　are　an
  imposter！　　Discover　some　invention　in　machinery　that　will　make
  the　rich　more　rich　and　the　poor　more　poor；　and　they　will　build
  you　a　statue！　　Discover　some　mystery　in　art　that　will　equalise
  physical　disparities；　and　they　will　pull　down　their　own　houses　to
  stone　you！　　Ha；　ha；　my　pupil！　such　is　the　world　Zanoni　still

  that　you　have　seen　some　few　of　the　effects　of　science；　begin　to

  Mejnour　then　set　before　his　pupil　certain　tasks；　in　which　the
  rest　of　the　night　wore　itself　away。

  。。。He；　there　besyde
  Saw　a　faire　damzell。
  Spenser；　〃Faerie　Queene；〃　cant。　ix。
  For　a　considerable　period　the　pupil　of　Mejnour　was　now　absorbed
  in　labour　dependent　on　the　most　vigilant　attention；　on　the　most
  minute　and　subtle　calculation。　　Results　astonishing　and　various
  rewarded　his　toils　and　stimulated　his　interest。　　Nor　were　these
  studies　limited　to　chemical　discovery；in　which　it　is　permitted
  me　to　say　that　the　greatest　marvels　upon　the　organisation　of
  physical　life　seemed　wrought　by　experiments　of　the　vivifying
  influence　of　heat。　　Mejnour　professed　to　find　a　link　between　all
  intellectual　beings　in　the　existence　of　a　certain　all…pervading
  and　invisible　fluid　resembling　electricity；　yet　distinct　from　the
  known　operations　of　that　mysterious　agencya　fluid　that
  connected　thought　to　thought　with　the　rapidity　and　precision　of
  the　modern　telegraph；　and　the　influence　of　this　fluid；　according
  to　Mejnour；　extended　to　the　remotest　past；that　is　to　say；
  whenever　and　wheresoever　man　had　thought。　　Thus；　if　the　doctrine
  were　true；　all　human　knowledge　became　attainable　through　a　medium
  established　between　the　brain　of　the　individual　inquirer　and　all
  the　farthest　and　obscurest　regions　in　the　universe　of　ideas。
  Glyndon　was　surprised　to　find　Mejnour　attached　to　the　abstruse
  mysteries　which　the　Pythagoreans　ascribed　to　the　occult　science
  of　NUMBERS。　　In　this　last；　new　lights　glimmered　dimly　on　his
  eyes；　and　he　began　to　perceive　that　even　the　power　to　predict；　or
  rather　to　calculate；　results；　might　by　（Here　there　is　an
  erasure　in　the　MS。）
  。。。
  But　he　observed　that　the　last　brief　process　by　which；　in　each　of
  these　experiments；　the　wonder　was　achieved；　Mejnour　reserved　for
  himself；　and　refused　to　communicate　the　secret。　　The　answer　he
  obtained　to　his　remonstrances　on　this　head　was　more　stern　than
  satisfactory：
  〃Dost　thou　think；〃　said　Mejnour；　〃that　I　would　give　to　the　mere
  pupil；　whose　qualities　are　not　yet　tried；　powers　that　might
  change　the　face　of　the　social　world？　　The　last　secrets　are
  intrusted　only　to　him　of　whose　virtue　the　Master　is　convinced。
  Patience！　　It　is　labour　itself　that　is　the　great　purifier　of　the
  mind；　and　by　degrees　the　secrets　will　grow　upon　thyself　as　thy
  mind　becomes　riper　to　receive　them。〃
  At　last　Mejnour　professed　himself　satisfied　with　the　progress
  made　by　his　pupil。　　〃The　hour　now　arrives；〃　he　said；　〃when　thou
  mayst　pass　the　great　but　airy　barrier；when　thou　mayst　gradually
  confront　the　terrible　Dweller　of　the　Threshold。　　Continue　thy
  labourscontinue　to　surpass　thine　impatience　for　results　until
  thou　canst　fathom　the　causes。　　I　leave　thee　for　one　month；　if　at
  the　end　of　that　period；　when　I　return；　the　tasks　set　thee　are
  completed；　and　thy　mind　prepared　by　contemplation　and　austere
  thought　for　the　ordeal；　I　promise　thee　the　ordeal　shall　commence。
  One　caution　alone　I　give　thee：　　regard　it　as　a　peremptory
  command；　enter　not　this　chamber！〃　　（They　were　then　standing　in
  the　room　where　their　experiments　had　been　chiefly　made；　and　in
  which　Glyndon；　on　the　night　he　had　sought　the　solitude　of　the
  mystic；　had　nearly　fallen　a　victim　to　his　intrusion。）
  〃Enter　not　this　chamber　till　my　return；　or；　above　all；　if　by　any

  open　the　vases　on　yonder　shelves。　　I　leave　the　key　of　the　room　in
  thy　keeping；　in　order　to　try　thy　abstinence　and　self…control。
  Young　man；　this　very　temptation　is　a　part　of　thy　trial。〃
  With　that；　Mejnour　placed　the　key　in　his　hands；　and　at　sunset　he
  left　the　castle。
  For　several　days　Glyndon　continued　immersed　in　employments　which
  strained　to　the　utmost　all　the　faculties　of　his　intellect。　　Even
  the　most　partial　success　depended　so　entirely　on　the　abstraction
  of　the　mind；　and　the　minuteness　of　its　calculations；　that　there
  was　scarcely　room　for　any　other　thought　than　those　absorbed　in
  the　occupation。　　And　doubtless　this　perpetual　strain　of　the
  faculties　was　the　object　of　Mejnour　in　works　that　did　not　seem
