On the morning of December 21, a jar containing fifteen hungry
mosquitoes, that had previously stung cases of yellow fever,
was introduced and uncovered in the larger compartment, where a
bed, with all linen perfectly sterilized, was ready for
occupancy. A few minutes after, Mr. Moran, dressed as though
about to retire for the night, entered the room and threw
himself upon the bed for half an hour; during this time two
other men and Major Reed remained in the other compartment,
separated from Moran only by the wire-screen partition. Seven
mosquitoes were soon at work upon the young man"s arms and
face; he then came out, but returned in the afternoon, when
five other insects bit him in less than twenty minutes. The
next day, at the same hour of the afternoon, Moran entered the
'mosquito building' for the third time and remained on the bed
for fifteen minutes, allowing three mosquitoes to bite his
hands. The room was then securely locked, but the two Americans
continued to sleep in the other compartment for nearly three
weeks, without experiencing any ill effects.
