line by raising up its body, we brought within three inches of its spinnerets an excited stick of sealing-wax, of which it took no notice, nor did any thread extend to it, not even when brought almost to touch the spinnerets. We experienced the same want of success with an excited glass rod; and indeed had not anticipated any other result, as we have never observed that either these attract or repel the floating threads, as Mr. Murray has seen them do; nor have we ever noticed the end of a floating thread separated into its component threadlets and diverging like a brush, as he and Mr. Bowman describe (See Fig. 11.). It may be proper to mention that Mr. Murray, in conformity with his theory, explains the shooting of lines in a current of air by the electric state produced by motion in consequence of the mutual friction of the gaseous particles. But this view of the matter does not seem to affect our statements."
Nests, Webs, and Nets of Spiders.—"The neatest," says Mr. Rennie, "though the smallest spider's nest which we have seen, was constructed in the chink of a garden-*post, which we had cut out the previous summer in getting at the cells of a carpenter-bee. The architect was one of the larger hunting-spiders, erroneously said by some naturalists to be incapable of spinning. The nest in question was about two inches high, composed of a very close satin-like texture. There were two parallel chambers placed perpendicularly, in which position also the inhabitant reposed there during the day, going, as we presume, only abroad to prey during the night. But the most remarkable circumstance was, that the openings (two above and two below) were so elastic, that they shut closely together. We observed this spider for several months, but at last it disappeared, and we took the nest out under the notion that it might contain eggs; but found none, and therefore concluded that it was only used as a day retreat." The account which Evelyn has given of these hunting spiders is so interesting that we must transcribe it.
"Of all sorts of insects," says he, "none have afforded me more divertisement than the venatores (hunters), which are a sort of lupi (wolves) that have their dens in rugged
