bt the other proposition, though logical,
after all, and agreeing with the methods followed by a host of
parasites. No matter: my faith in what I read in print is of the
slightest; I prefer to go straight to facts. Before making a statement
of any kind, I want to see, what I call seeing. It is a slower and more
laborious process; but it is certainly much safer.

I will not undertake to lie in wait for what takes place on the
cabbages in the garden: that method is too uncertain and besides does
not lend itself to precise observation. As I have in hand the necessary
materials, to wit, my collection of tubes swarming with the parasites
newly hatched into the adult form, I will operate on the little table
in my animals' laboratory. A jar with a capacity of about a litre
(About 1 3/4 pints, or .22 gallon.--Translator's Note.) is placed on
the table, with the bottom turned towards the window in the sun. I put
into it a cabbage-leaf covered with caterpillars, sometimes fully
developed, sometimes half-way, sometimes just out of the egg. A strip
of honeyed paper will serve the Microgaster as a dining room, if the
experiment is destined to take some time. Lastly, by the method of
transfer which I described above, I send the inmates of one of my tubes
into the apparatus. Once the jar is closed, there is nothing left to do
but to let things take their course and to keep an assiduous watch, for
days and weeks, if need be. Nothing worth remarking can escape me.

The caterpillars graze placidly, heedless of their terrible attendants.
If some giddy-pates in the turbulent swarm pass over the caterpillars'
spines, these draw up their fore-part with a jerk and as suddenly lower
it again; and that is all: the intruders forthwith decamp. Nor do the
latter seem to contemplate any harm: they refresh themselves on the
honey-smeared strip, they come and go tumultuously. Their short flights
may land them, now in one place, now in another, on the browsing herd,
but they pay no attention to it. What we see is casual meetings, not
deliberate encounters.

In vain I change the flock of caterpillars and vary their age; in vain
I change the squad of parasites; in vain I follow events in the jar for
long hours, morning and evening, both in a dim light and in the full
glare of the sun: I succeed in seeing nothing, absolutely nothing, on
the parasite's side, that resembles an attack. No matter what the
ill-informed authors say--ill-informed because they
