on of a Butterfly's
progeny!

I am fortunate at this moment in having a highly-cultured visitor,
versed in the profundities of philosophic thought. I make way for him
before the apparatus wherein the Microgaster is at work. For an hour
and more, standing lens in hand, he, in his turn, looks and sees what I
have just seen; he watches the layers who go from one egg to the other,
make their choice, draw their slender lancet and prick what the stream
of passers-by, one after the other, have already pricked. Thoughtful
and a little uneasy, he puts down his lens at last. Never had he been
vouchsafed so clear a glimpse as here, in my finger-wide tube, of the
masterly brigandage that runs through all life down to that of the very
smallest.
