plant which produces the Scammony is a fpecies of Convolvulus, very fimilar to that which we have now
Jpbed; hence Dr. Cullen, and fome' other Phyficians, have conjectured, that our Convolvulus might poffefs
J p properties; bur, if it fhould be found to contain fuch properties, the fmallnefs of its roots would prevent
wuice from being colleóted in the fame manner with that which flows on incifion from the large root of the 5 Nony plant, and which hardens and forms that purgative fubftance. Whether an extract made from the
jpl'ed juice of the roots, or any other preparation of them, might poflefs a purgative property; or, if it fhould,
Jther«Juch a purgative would be fo far iuperior to any now in general ufe as to introduce it defervedly into practice;
iHbat we cannot pretend to decide on. Hogs are faid to eat, and even to bè fond of, the roots.
Hr gr°ws exceedingly common in our hedges, and flowers in Auguft and September. Where it has once gained
H ^ v i t is with the greateft difficulty eradicated: was it not for this property, and its being fo common, it would
HMlefs be confidered, as it really is, a very ornamental plant.

^Bowledge of our Engliffi InfeCls), informs me, that the Caterpillar of the Phalana Vibicaria, or Bloody-vein Moth
