Male fern extract. 
Southall Bros., & Barclay, Lab. Rep., 20, p. 15. 
The statement of Parry that much of the male fern extract is adulterated 
is confirmed. The physical and chemical constants obtained in the ex¬ 
amination of six commercial extracts are tabulated.

It is stated that there was hardly any variation in the percentage of 
oleoresin in the samples of cubebs examined during the last six years,

The determination of the ether extract of male fern, and the 
unification of the methods of analysis. 
Bull. Sci. Pharmacolog., 19, p. 705, [Pharm. Ztg., 58, p.

It is stated that the method of the Swiss Codex gives values for crude 
filicin which are about 30 per cent, too high owing to the solubility of 
the ether solution in the solution of barium hydroxide. If the ether be 
driven off by heating to 50°C before filtering, the results will be com¬ 
parable with those obtained by the magnesia methods.

Notes on Indian drugs. 
Pharm. Journ. 89, p. 391. 
The examination of the rhizomes of Indian ginger, with reference to de¬ 
termining the relationship between maturity and oleoresin content, showed 
that young rhizomes develop oleoresin as they are allowed to grow. Those 
gathered in December yielded 6.4 per cent, of extract to alcohol (90 per 
cent.), while those gathered in February gave 8.3 per cent. Upon washing 
the extracts with water, the remaining insoluble residue amounted to 3.0 
per cent, and 3.5 per cent., respectively. Some of the more mature rhizomes 
gave as high as 11.8 per cent, of alcoholic extract or 8.1 per cent, of 
washed resin.
