identity and strength of the several preparations. To avoid this, the 
new Pharmacopoeia gives to the fluidextracts a new alphabetic posi- 
tion, grouping them by themselves; thus Extractum Aconiti Fluidum 
(U. y. P., 1890) becomes Fluidextractum Aconiti in the Eighth Decen- 
nial Revision. lYherever practicable, assay processes have been intro- 
duced, thus ensuring preparations of definite and uniform strength. 
Many of the solid extracts are directed by the Eighth Revision to be 
made from the fluidextracts. 
Three fluidextracts, those of Lobelia, Sanguinaria and Squill, form- 
erly made with alcohol or (Sanguinaria) with alcohol, acetic acid and 
water, are now made with hydro-acetic acid. 
FLLIDEXTEACTOI BERBERIDIS. 
Fliiidextract of Berberis. 
Prepared from Berberis (q. v.). 
Dose. — “Average dose: 2 Cc. (30 minims).^’ (U. S. P.)

FLUIDEXTRACTUM URAXATI. 
Fliiidextract of Pomegranate. 
Hitherto only the bark of the stem and root of Granatum (Pome- 
granate) has been official ; it was often administered in the form of a 
decoction (official in the Br. P.), but this was verv unpleasant to take, 
owing to the large amount of tannic acid present. A mixture of the 
tannates of the most important active constituents (four alkaloids) of 
Granatum has also been introduced under the name PelletieriiiBB Tan- 
nas (q. v.). 
Dose. — “Average dose: 2 Cc. (30 minims).” (U. S. P.) 
FLUIDEXTRACTUM QUERCUS. 
Fliiidextract of Qiierciis. 
Prepared from the official Quercus (Quercus Alba, L^. 8. P., 1890), 
the bark of the white oak. The medicinal properties depend upon the 
tannin contained in the bark.

FLUIDEXTRACTU3I QUILLAJJ:. 
Fliiidextract of Quillaja.
