  But　there　is　one　point；　in　particular；　which　should　have　betrayed　the
  fiction。　Let　us　imagine　the　power　actually　possessed　of　seeing
  animals　upon　the　moon's　surface　　what　would　first　arrest　the
  attention　of　an　observer　from　the　earth？　Certainly　neither　their
  shape；　size；　nor　any　other　such　peculiarity；　so　soon　as　their
  remarkable　_situation_。　They　would　appear　to　be　walking；　with　heels
  up　and　head　down；　in　the　manner　of　flies　on　a　ceiling。　The　_real_
  observer　would　have　uttered　an　instant　ejaculation　of　surprise
  （however　prepared　by　previous　knowledge）　at　the　singularity　of　their
  position；　the　_fictitious_　observer　has　not　even　mentioned　the
  subject；　but　speaks　of　seeing　the　entire　bodies　of　such　creatures；
  when　it　is　demonstrable　that　he　could　have　seen　only　the　diameter　of
  their　heads！
  It　might　as　well　be　remarked；　in　conclusion；　that　the　size；　and
  particularly　the　powers　of　the　man…bats　（for　example；　their　ability
  to　fly　in　so　rare　an　atmosphereif；　indeed；　the　moon　have　any）；　with

  that　all　the　suggestions　attributed　to　Brewster　and　Herschel；　in　the

  might　have　them　of　any　size　demanded。　But；　unhappily；　in　proportion
  to　the　increase　of　size　in　the　lens；　and　consequently　of
  space…penetrating　power；　is　the　diminution　of　light　from　the　object；
  by　diffusion　of　its　rays。　And　for　this　evil　there　is　no　remedy　within
  human　ability；　for　an　object　is　seen　by　means　of　that　light　alone
  which　proceeds　from　itself；　whether　direct　or　reflected。　Thus　the
  only　〃artificial〃　light　which　could　avail　Mr。　Locke；　would　be　some
  artificial　light　which　he　should　be　able　to　throw…not　upon　the　〃focal
  object　of　vision；〃　but　upon　the　real　object　to　be　viewed…to　wit：　upon
  the　moon。　It　has　been　easily　calculated　that；　when　the　light
