270 Uvularia perfoliata as a remedy for Poisoned Wounds. 
- The shell- here published as the Unio Sayii, in honor of the 
ist American conchologist, has been supposed by Mr. Lea to be 
“a middle aged camptodon of Say,” and by Mr. Conrad and 
some others, to be the declivis of Say. Without entering into a 
minute comparison here, let those who have the Unios campto- 
don and declivis of Say and this shell, compare them with each 
other, and they will be compelled to agree that they are three dis- 
tinct and well marked species. Those who have not the shells 
to compare, will arrive at the same conclusion, by a careful com- 
parison of the drawings of the declivis, plate 35, of the American 
Conchology ; of the camptodon, plate 42, of the same work ; and 
the drawing, No. 1; herewith given: all by the same accurate 
~ and skillful hand. ° In general, the western conchologists adopt 
t 
Mr. Lea’s classification and nomenclature of the Naiades, with 
perhaps but one exception, the mytiloides, which they are not 
able to find in Rafinesque’s © Monocrapu. But in dissenting 
from his opinion in this instance, and calling the Unio Sayii a 
new and undescribed ‘shell, the opinion of Dr. Ward is supported 
by all those conchologists; nor does it seem probable to them that 
Mr. Lea would have called it a camptodon, or Mr. Conrad and 
ie a declivis, if they had carefully examined many a

Wane at Pottsville, in July, 1838, I was called ‘upon to visit 
a girl about five years of age, alleged to have been bitten by a rat- 
tlesnake, but as it afterwards appeared, probably bya copper-head, 
(Trigonocephalus contortrix.) When Isaw the patient, three hours 
had elapsed ; but the parent, an intelligent man, stated that the 
pain produced by the bite had greatly abated dindet the applica- 
tion of a plant obtained from the forest, and applied bruised and 
moistened with salted vinegar. Although crushed, the plant ap- 
peared on inspection, to be the Uvularia perfoliata ; and its identity 
was afterwards verified by fresh specimens obtained for me by 4
