The fird Method of preparing it ufed by the 
Ancients is delcribed by Galen thus, 1 . 1. concerning 
the Qualities of Aliments. They fcooped out the 
Seeds and fome of the Pulp of a Quince, and fill- 
ing the Cavity with Scammony, covered it with 
Pade made of Meal and Water, and roaded it : 
Then they gave the Quince to be eaten together 
with the Scammony. At prefent the Pulp is com- 
monly thrown away, and the Scammony retained. 
Others retain the Pulp, and rejedt the Scammony : 
And others, with Galen , retain both. 
In what Manner foever this Medicine is prepared, 
it is now called in the Shops Diacrydium , Diagry- 
dium , and Diadagrydium , to didinguilh it from crude 
Scammony. The Preparation abovementioned is 
termed Diagrydium Cydoniatum . 
The Ancients like wife tempered it with the Cream 
of their Ptifan, as may be feen in Galen in the Place 
above quoted. Mefue bakes it under Gledes, or 
in an Oven, with the Seeds of Daucus, of Fennel, 
and with Galangal. Valerius Cordus macerates it in 
Oil of Violets by Infufion ; then roads it in a 
Quince covered with Pafle; and laflly, pouring 
upon it the Juice of Quinces in which Myrobalans 
have been infufed, fets it in a warm Place to dry. 
Again, fome only mix it with the exprefled Juice 
of Quinces, and gradually evaporate it. 
The Moderns have attempted to corredl its ma- 
lignant Quality with the Juice of Liquorice, or 
with Sulphur : Whence it is named Diagrydium gly- 
cyrrhizatum , or Sulphuratum. The firft is prepared 
by boiling a fufficient Quantity of Liquorice in com- 
mon Water, which they drain and evaporate to the 
Thicknefs of a Syrup. Then they add q. f. of 
choice Scammony, reduced to a fine Powder, and 
placing the Mixture in B. M. flir it about continu- 
ally, till it acquires the Confidence of an Extract,
