asa narcotic in cases of fever, was recommended by many 
physicians in this country; but now it is probably seldom 
used. The author being absent from Philadelphia when the 
second volume of the Journal was published, a strange mis- 
take was committed. "The publishers caused a delineation of 
my Lycosa lenta to be printed instead of the original draw- 
ihg of this species, which was probably lost; and as soon as 
they were informed of the error, they caused an imperfect 
delineation of this species to be substituted, which may be 
seen on Plate V., along with some representations of crystals 
of Zircon, published by Dr. G. Troost. The palpi of the 
male of this spider are very complicated, as may be seen by 
the drawing. The colors vary much. 
On the 28th of February, I observed a male specimen of 
this species in a dark corner, apparently devouring another 
spider. On moving them with a straw I discovered that the 
other was a female of the same species, and not dead, but 
With its legs closely folded on its body, and perfectly motion- 
One of the palpi of the male was buried in the vulva 
of the female, and could not be extricated by the efforts which 
e made to avoid my intruding straw. I threw them on the 
Sround and had ceased to watch them, when suddenly I saw 
| female escaping from him, apparently in great terror. In 
the meanwhile, the male, from whose cheliceres she had 
"aped, had seized a small bit of stick as a substitute, and 
"an about with ludicrous haste, seemingly out of his senses for 
Some time. This fact may prove that the female of spiders is 
hot always the tyrant and oppressor of the other sex. |
