istance, upon the Balcony (where I stood) would not make
directly to her, but craul under the Rail, till being arriv'd to the
_Antipodes_, it would steal up, seldom missing its aim; but if it
chanced to want any thing of being perfectly opposite, would at first
peep, immediatly slide down again, till taking better notice, it would
come the next time exactly upon the Fly's back: But, if this hapn'd not
to be within a competent leap, then would this Insect move so softly,
as the very shadow of the Gnomon seem'd not to be more imperceptible,
unless the Fly mov'd; and then would the Spider move also in the same
proportion, keeping that just time with her motion, as if the same Soul
had animated both those little bodies; and whether it were forwards,
backwards, or to either side, without at all turning her body, like a
well mannag'd Horse: But, if the capricious Fly took wing, and pitch'd
upon another place behind our Huntress, then would the Spider whirle
its body so nimbly about, as nothing could be imagin'd more swift; by
which means, she always kept the head towards her prey, though to
appearance, as immovable, as if it had been a Nail driven into the
Wood, till by that indiscernable progress (being arriv'd within the
sphere of her reach) she made a fatal leap (swift as Lightning) upon
the Fly, catching him in the pole, where she never quitted hold till
her belly was full, and then carried the remainder home. I have beheld
them instructing their young ones, how to hunt, which they would
sometimes discipline for not well observing; but, when any of the old
ones did (as sometimes) miss a leap, they would run out of the field,
and hide them in their crannies, as asham'd, and haply not be seen
abroad for four or five hours after; for so long have I watched the
nature of this strange Insect, the contemplation of whose so wonderfull
sagacity and address has amaz'd me; nor do I find in any chase
whatsoever, more cunning and Stratagem observ'd: I have found some of
these Spiders in my Garden, when the weather (towards the Spring) is
very hot, but they are nothing so eager of hunting as they are in
_Italy_.

There are multitudes of other sorts of Spiders, whose eyes, and most other
parts and properties, are so exceedingly different both from those I have
describ'd, and from one another, that it would be almost
