streaks. When I look for some term to designate this digestive
entrance, of which so far I know no other example, I can find only
that of a sucker or cupping glass. Its attack is a mere kiss, but
what a perfidious kiss!

We know the machine; now let us see the working. To facilitate
observation, I shifted the newborn Anthrax grub, together with the
Chalicodoma grub, its wet nurse, from the natal cell into a glass
tube. I was thus able, by employing as many tubes as I wanted, to
follow from start to finish, in all its most intimate details, the
strange repast which I am going to describe.

The worm is fixed by its sucker to any convenient part of the
nurse, plump and fat as butter. It is ready to break off its kiss
suddenly, should anything disquiet it, and to resume it as easily
when tranquillity is restored. No Lamb enjoys greater liberty
with its mother's teat. After three or four days of this contact
of the nurse and nursling, the former, at first replete and
endowed with the glossy skin that is a sign of health, begins to
assume a withered aspect. Her sides fall in, her fresh color
fades, her skin becomes covered with little folds and gives
evidence of an appreciable shrinking in this breast which, instead
of milk, yields fat and blood. A week is hardly past before the
progress of the exhaustion becomes startlingly rapid. The nurse
is flabby and wrinkled, as though borne down by her own weight,
like a very slack object. If I move her from her place, she flops
and sprawls like a half-filled water bottle over the new
supporting plane. But the Anthrax' kiss goes on emptying her:
soon she is but a sort of shriveled lard bag, decreasing from hour
