should be more fully defined so as to direct the gradual addition of 
the alcohol, or to modify the test entirely. — Pharm. Ztg., Berlin, 
1905, v. 50, p. 672. 
Stadlinger, Hermann, presents a comprehensive article on the ex- 
amination of honey; chemical, physical, and microscopical. — Pharm. 
Ztg., Berlin, 1905, v. 50, pp. 536 and 549. 
An abstract discusses the suggestion made by Herm. Ley to dilute 
the hone} 7 that is to be purified, adding a small proportion of alcohol 
and sufficient lime water to make the solution neutral or slightly 
alkaline. After filtering the solution may be treated with oxalic acid 
to remove the lime, again filtered and then concentrated to the proper 
consistency. — Deut.-Amer. Apoth. Ztg., N. Y., 1905, v. 26, p. 23.

The re visors of Vienna pharmacies (from Ztschr. d. oesterr. Apoth. 
Ver.) report Mentha piperita frequently contaminated with the 
leaves of Mentha viridis , and in one instance the leaves of Atropa bel- 
ladonna. The latter admixture, they point out, while no doubt acci-
