Friend. J. A. N. (Proc. Chem. Soc., 1905, v. 21, p. 133), outlines a 
-process for tlie estimation of potassium permanganate in the presence 
of potassium persulphate. — Pharm. Ztg., Berlin, 1905, v. 50, p. 603. 
Gardner and North have made a series of experiments with solu- 
tions of potassium permanganate and of ammonium oxalate and con- 
clude that solutions of the former when made with pure ingredients 
are stable and will readily keep for at least twelve months without 
deterioration. — Abstr. in Deut.-Amer. Apoth. Ztg., N. Y., 1905, v. 26, 
p- i7 - 
Lemaire (Repert. de Pharm.) has experimented with a number 
of nonoxidizable substances that might be of use for the making of 
caustic points of potassium permanganate. He finds that sodium 
phosphate, containing about 12 molecules of water, melts at 10° C. 
and answers admirably for the production of points by moulding 
them in suppository moulds. — Pharm. Zentralli., 1905, v. 46, p. 861. 
An abstract (from Munch. Med. Wnhnschr.) recommends a mix- 
ture of 2 parts of potassium permanganate, 1 part of kieselguhr and 
1 part of paraffin ointment as a haemostatic, to be used in minor oper- 
ations, nose bleed and similar cases. — Pharm. Ztg., Berlin, 1905, 
v. 50, p. 804. 
POTASSII ET SODII TARTRAS. 
Kebler, Lyman F., reports finding potassium and sodium tartrate 
that was very dirty and contained iron salt and chloride. — Proc. Am. 
Pharm. Ass., 1905, v. 53, p. 189. 
Meredith, II. L., reports on a sample of potassium and sodium tar- 
trate which analysed from 55-57 per cent of potassium and sodium 
tartrate, the remainder a very inferior sodium bicarbonate. — Proc. 
Maryland Pharm. Ass., 1905, p. 55. 
PRUNUM. 
Eberle, E. G., mentions Primus domestica and serotina as occurring 
in Texas. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 305. 
PRUNUS VIRGINIANA. 
Havenhill, L. D., points out that lack of conformity to degree of 
fineness of powder specified is accountable for the reported difficul- 
ties in percolating wild cherry and the lack of uniformity of prepara- 
tions. — Proc. Kansas Pharm. Ass., 1905, p. 93. 
PUL VIS GLYCYRRHIZJE COMPOSITUS. 
Evans, J. (Pharm. J., Lond.), gives tabulated results of examina- 
tions of 5 samples, including amount of ash and the alcohol soluble 
extract. — Year Book of Pharmacy, Loncl., 1905, p. 267.
