and roots have been given, from a quarter of a grain to four or five, 
in the form of pills, powder or extract ; it has also been exhibited in 
the forms of tincture,* and infusion ; topically the leaves have been 
applied in their recent state, or formed into a poultice; the dried 
leaves have also been applied in the form of powder. The extract 
diluted with four or six times its weight of simple unguent, or from ten 
to thirty grains of the extract, dissolved in eight ounces of water,

TORMENTILLA ERECTA. 
Common Tormentil, or Stptfoil.^; 
Class IcosANDRiA. — Order Polygynia. 
Nat. Ord. Senticos^, Linn. RosACEiE, Juss. 
Gen. Char. Calyx eight-cleft, alternate divisions smaller. 
Corolla 4-petalled. Seeds 8, roundish, naked, enclosed in 
the calyx. 
Spec. Char. Stem somewhat erect, branched. Leaves 
ternate, sessile. 
This species of Tormentilla, as also another, the Tormentilla 
Reptans, is indigenous to Great Britain ; growing on dry, heathy 
grounds, and by the road sides. Linnaeus says, " Genus hoc artifi- 
ciale magis quam naiurale esse, ipse agnosco, et qui illud conjungit 
cum pracedenti, (Potentilla) vix errat." I 
* Mr. Biackett recommends the following tincture, which he has used with yery 
great success: — " To ten fluid drachms of the expressed juice of the leaves, add sixteen 
ounces of proof spirit, allow to macerate for tweoty-one days, and strain for use." 
The above we think one of the best preparations of Belladonna, being admirablj 
suited for the gradual increase of this powerful medicine. — Ed.
