The plant which produces the Scummy is a fpecies of Convolvulus, very fimilar to that which wekejw 

 defcribed, hence Dr. Cullen and fome other Phyficians have conje&ired that our Convolvulus might poflef 

 fim lar properties, but if it mould be found to contain fuch properties the fmallnefs of it roots ^prevent 

 its iuice from being collected in the fame manner with that which flows on incifion from the large root 

 of tL^ Scammony pfant, and which hardens and forms that, purgative fubftance. J^J*^_^

My ingenious Friend Mr. Church, Surgeon, at Iflington, (who has taken much pains te , coUefl ^ and ae- 

 on re a knowledge of our Englifli InfeCts) informs me that the Caterpillar of the Ph^naV,b,ca,aor Bloody
