When Type Process C is directed for fluidextraets which are 

 adjusted by assay to a definite alkaloidal standard, collect only four 

 hundred and twenty mils of percolate from the third portion of 

 the drug instead of the five hundred mils as directed above. Mix 

 this percolate with the two portions previously reserved, assay a 

 portion of the mixture and then adjust its volume, by the addi- 

 tion of the menstruum directed, so that each one hundred mils of 

 finished fluidextract will contain the prescribed amount of alkaloid. 



Type Process D. To one thousand grams of the ground drug 

 add five thousand mils of boiling water, mix thoroughly and allow 

 it to macerate in a covered container for two hours in a warm place. 

 Then transfer the moist drug to a tinned or enameled metallic 

 percolator and allow percolation to proceed, gradually adding boil- 

 ing water until the drug is exhausted. Evaporate the percolate 

 on a water 'bath or steam bath to the volume specified, and when 

 cold add the alcohol directed and mix thoroughly. 



In making the following fluidextraets, calculate for 100.0 

 grams instead of 1000.0 grams.

 ciples of medicine substances, dissolved in wine. They may be pre-
