Extractum Filicis. 
Caesar and Loretz Jahres.-Ber., Aug. 1911, pp. 76 and 105. 
Regret is expressed in that the Ph. Germ. V. has not included an assay 
for oleoresin of aspidium. The crude filicin content is thought to be a 
satisfactory indication of the value of this preparation. A filicin con¬

physical and chemical constants, are tabulated.

Oil of male fern. 
Brit. & Col. Drugg., 60, p. 388. 
In this article, it is stated that parcels of the extract of male fern are 
being condemned in London as they have been found to contain large 
quantities of castor oil. 
Suspicion was first aroused through the low selling price of some
