Sur la composition chimique de la racine de fougere male, 
Polypodium filix mas Linn. 
Journ. de Pharm. et de Chim., 10, p. 223. [Mag. f. Pharm., 
7, p. 38.] 
In making a chemical examination of the male fern rhizomes, the author 
used the method of selective solvents. Upon extracting with ether, as the 
first solvent, and subsequently evaporating of the ether, a thick green fatty 
oil was obtained. The author considers this fatty substance the active 
principle.

Extractum Filicis maris resinosum. 
Repert f. d. Pharm., 23, p. 433. 
The preparation of this extract by means of alcohol instead of ether 
is recommended. The product thus obtained is spoken of as an Extractum 
resinosum. The Euile de Fougere of Peschier is spoken of as the harz- 
haltiges Oel. A chemical analysis of the extract is also given.

Farrnkrautwurzelextrakt. 
Arch. d. Pharm., 19, p. 153. 
The extract is reported to have been prepared by the process of macera¬ 
tion, ether being the solvent employed. Pour ounces of rhizomes gathered 
in August gave 108 grains of extract.
