alcohol. The residue remaining after removing the alcohol by evapora¬ 
tion is mixed with the volatile oil, this mixture constituting the so-called 
extract.

Ueber mehrere schon frueher erschienene Analysen der 
Farrenkrautwurzel (Aspidium filix mas L.) und ueber die 
Gewinnung seines harzigen Oels. 
Trommsdorff’s n. Journ. d. Pharm., 17, p. 5. 
The vermifuge properties of male fern are said to be due to its ol€o- 
resine (oelharz) content. This the author prepares by extracting the 
drug with ether and subsequently evaporating the solvent, (p. 8.) It is 
further stated that this oleosesine remains perfectly homogenous after 
months if prepared from freshly gathered rhizomes, but deposits a white 
granular substance when old rhizomes are used (p. 9.) 
According to the author’s analysis the oleoresine consists of a volatile 
aromatic oil, a fatty oil, resin, stearin, green and red coloring materials, 
acetic and gallic acids.

The “oil” extracted with ether is said to be a mixture of oil, resin 
and oxidized tannin. Twelve ounces of rhizomes gathered in February 
yielded 15 drachms of extract. Two drachms of this extract yielded 43 
grains of fatty oil.

The powdered rhizome of the male fern is directed to be extracted with 
alcohol and the alcoholic extract after evaporating off the solvent, washed 
with water. The extract is then further purified by solution in ether and 
subsequent evaporation.

Observations and Experiments on Peruvian Bark.

Pharm., 34, p. 446.] 
In the discussion of the therapeutic uses of the various constituents of 
Peruvian bark, it is stated that Dr. Chapman of Philadelphia prescribed 
piperin and oil of pepper in combination with quinine. The oil of pep¬ 
per is said to be the more active therapeutically, one drop of oil being 
equivalent to three grains of piperin (p. 39.)
