66. CoTifiihraiions on VegefabU Extraas. 



tinned, we may fee how extraols miift be preparetl in geire- 

 ral : but there is one which requires peculiar prcctflcs that 

 mutt be made known. • 



i(t. Robs of the cider and buckUinrn are made with juices 

 which ha^•c bccr^ extrafted 34 hours befofe tron) the berfies 

 of tliefe two flirubs. 



DiuMug that time, thefe juices become charoed with the 

 extradlive colouruig part lodsfed under the (km of the berries, 

 and by thele means acquire more virtue. 

 _ 2d. Ex-traft of juniper is obtained by maceration of frefh 

 jumper hemes which have been bruiCed. Tlicy are evapo- 

 rated m a gentle heat, after being made to pafs througU 

 flannel. r d 



It IS faccharine and aromatic: it wodd be acrid and re- 

 finous if cbuMition were employed. Baume, however, has 

 preicnbcd it ; but he made it hgin, and reeonnuended not to- 

 bruilc the berries. 



3d. Extraas of caffia and tamarinds are all produas of the 

 maceration and pnlp of thefe fruits. 



Tnfufion of tamarinds, cold, is attended with the inconve- 

 nience of fuffenng their elfential fait to be precipitated during, 

 the evaporation. 



4th. Extraa of the corn poppy is produced by carefully 

 inhifing the dried flowers. " •' ' 



5th That obtained from faflfron is very abundant; almofi: 

 the whole of its (famina are converted into extraaj fo that 

 It may be confitlered as nfelcfs to fubjea them to this pre- 

 paration, which, altering their virtue a little, does not re- 

 duce them, to a Icfs volume. 



6th. The extraa of coloquintida is made with a decoaiou 

 ot the pulp of that fruit freed from the feeds. To render it. 

 jweeter, and make it lefs fufceptible of oriplntr the bowels. 

 It ought to be deprived of its retin. ° 



Eaume caufed it to be redifl'ohed in cold water. He fil- 

 trated the liquor, and the refin remahied on the paper. Thi* 

 operation he repeated three times. 



7th. Opium is brouoJit to us from Turkey. The praaice 

 of making It near the ruins of Thebes has been loft. Tha 

 inhabilants of Egypt Hill cultivate the plant which furnifhes 

 !t ; but only to oat the feeds, which thev are fond of, as well 

 as of all other cmulfive feeds. 



Opium is an extract prepared from the exprelTed juice of 

 the eaves, ftoms, and heads of the white popoy. 



Ihat ufed m commerce is very impure. Tiie preparer of 

 opium dilloives u in water, makes the liquor pufs through 



fiiuuiel^
