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. S. P., 1890) becomes Fluidextraetum Aconiti in the Eighth Decen- 
nial Revision. Wherever 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. 
FLUIDEXTRACTUM BERBERIDIS. 
Fluidextract of Beriberis. 
Prepared from Berberis (q. v.). 
Dose. — “Average dose: 2 Cc. (30 minims).” (IT. S. P.) 
FLUIDEXTRACTUM EUONTMI. 
Flnidextract of Enonymus. 
The solid extract of Enonymus, which was already official, is now 
prepared from this fluidextract. 
Dose. — “Average dose: 0.5 Cc. (8 minims).” (IT. S. P.) 
FLUIDEXTRACTUM GRANATI. 
Fluidextract 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 very 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 Pelletierinse Tan- 
nas (q. v.). 
Dose. — “Average dose: 2 Cc. (30 minims).” (E. S. P.) 
FLUIDEXTRACTUM QUERCUS. 
Fluidextract of Quercus. 
Prepared from the official Quercus (Quercus Alba, U. S. P., 1890), 
the bark of the white oak. The medicinal properties depend upon the 
tannin contained in the bark. 
Dose. — “Average dose: 1 Cc. (15 minims)." (IT. S. P.) 
FLUIDEXTRACTUM QUILLAEE. 
Fluidextract of Quillaja. 
The tincture of Quillaja (soapbark) was already official. 
It has sometimes been proposed to use quillaja or one of its most 
important constituents (saponin) as an emulsifying agent for cod-liver
