Outleading

It never will be known how it happened — whether Miss Conway ha , in that moment of excitement, failed to take a glance at the wall-star at the end, and turned with her companion into one of the long outleading corridors, or whether she had absolutely forgotten her geography of the place in the blackness that was upon them, for she had never contemplated passing more than a few steps beyond the entrance to the cave.

It worked. Young dogs were made unconscious with an anesthetic, and the outleading ducts of the pancreas ligated.

Could it be by the outleading effects of joy?
