separate from each other, but occasionally they remain connected by 
a bridge of substance, and in some cases this is elongated, so that 
when several daughter-nuclei in succession are thus joined they 
resemble a rosary. 
Both forms of fragmentation may occur side by side in the same 
muscle, and even in the same nucleus. Besides these nearly trans- 
verse divisions, a longitudinal splitting of the nucleus is sometimes 
met with. t. 
Are the Solpugids Poisonous ?— It has long been a disputed 
question as to whether the arachnids known as Solpugids are poison- 
ous or not. In the regions where they occur they have a very bad 
reputation; but naturalists who have studied their structure have 
never found poison glands or ducts. Recently Lónnberg! has 
described his observations on Galeodes araneoides in the neighbor- 
hood of Baku, on the Caspian. He found that the “falanger,” as 
the Russians call it, did not poison insects and other animals upon 
which it preyed. In attacking a small scorpion it crushed one of 
the slender joints of the abdomen and then the segment containing 
the poison sac. It next attacked the larger abdominal segments, 
working its jaws into the interior and devouring the flesh. During 
this whole time the scorpion struggled and fought, moving freely and 
showing no sign of being poisoned. It could not penetrate the skin 
of a frog, although it attempted to bite it several times. Finally 
Lónnberg and a friend both allowed the Galeodes to attempt to bite 
them; but its jaws were not strong enough to penetrate the thick- 
ened skin of the finger tips, while flies which were bitten, but which 
did not have the nervous system injured, were able to crawl around 
along time after being bitten. These facts, together with the ab- 
sence of openings in the chelæ through which poison could escape, 
led Lönnberg to the conclusion that Galeodes at least is not veno- 
mous. At the time for hibernation it dug into the ground, using the 
two anterior pairs of legs, but where the earth was harder it used the 
chelz to remove small stones and bits of clay. 
New Jersey Insects. .— Professor J. B. Smith's list of the insects
