a reward of examination from the generic fimilarity: when thefe are 
actually in ufe among the people of this country, the probability of their 
value is the greater. 
An application of thefe principles will bring the following plants to 
our particular notice—Agrimony, Potentilla~quinquefolium, P lygonum- 
biftorta, Gentiana, Fumaria, Angelica, Cochlearia, Eryfimum officinale, 
Arum, Symphitum, Jnula campana, Afarum, all growin thenorthern and 
middle ftates; and are the fame with, or near a-kin to thofe clafled 
among the beft fimples by Dr. Cullen in his Materia Medica*. The gen- 
tiana growing in the g/ades of Pennfylvania, is by Dr. Sch. efteemed 
the belt of our feveral fpecies. The Arum of North America is generally 
called Indian turnep, from its ancient value among the Indians ; and of- 
ten ufed with other ingredients by the country people, in that general 
debility, confequent on tedious fevers.—The beft recommended remedies, 
againft intermittent fevers, are Cornus Jlorida, Dogwood ; Quercus phel-

maculata, with the Indian name pipfffeva: Sambucus canadenfis : 
Laurus 2/ivalis, Spicewood, Benjamin-tree, Benzoin. The firft is more 
generally known: a decoction of the bark has in many cafes been ef- 
fetual; it is by fome deemed equal, when frefh, to the Peruvian :} 
The fecond is much valued in the fouth, its native place: that of Perfi- 
mon in North Carolina; and of Lonicera Syphoricarpos in Virginia.t 
Aninfufion of the plant Pyrola maculata has been frequently ufed for 
fome years in Pennfylvania, under.the name of pipfifeva.§ The Sam- 
bucus canadenfis, Red berry elder, is by the Indians called the fever-bufh ; 
a decoétion of its wood and buds being of ancient renown among them. 
The laurus @/fivalis, Spicewood, Benjamin-tree, is alfo diftinguifhed with - 
that name by the people in the northern parts, for the falutary decoétion 
of its wood and leaves.|| The bark of the Liriodendron, Tulip-tree, is 
alfo very generally efteemed a good fubftitute for the peruvian : efpeci-
