leaves are smoked and chewed like tobacco, and made into a tea. — 
Merck's Report, X. Y., 1906, v. 15, p. 95. 
Power and Tutin record a chemical examination of eriodictyon. 
They review the literature relating to this plant, record the experi- 
ments carried out, and conclude that Eriodictyon calif drnicum con- 
tains, in addition to some essential oil, resins and other amorphous 
bodies, triacontane, eriodictyol, homo-eriodictyol, and a new yellow 
crystalline substance phenolic in character. — Proc. Am. Pharm. Ass., 
1906, v. 54, pp. 352-369. 
Caldwell, Paul, asserts that in order to produce a perfectly clear 
aromatic sirup of yerba santa X. F., the oils should be mixed with 
the fluid extract and alkali together with the water, and the whole 
filtered through magnesium carbonate until the filtrate makes a 
clear mixture with water. The sugar may then be added and dis- 
solved. — Drug. Circ. & Chem. Gaz., X. Y., 1906, v. 50, p. 159.

EUCALYPTOL. 
Schimmel & Co. assert that the specific gravity of eucalvptol, at 
25° C., is not 0.925, as originally given in the U. S. P. VIII but 
varies between 0.921 and 0.923. They point out that solidifica- 
tion has to be started in case of need by rubbing a glass rod on the 
wall of the vessel. They also assert that eucalyptol has been offered 
in commerce which, on examination, proved to be nothing else than 
a rectified oil of eucalyptus. — Semi- Ann. Rep., 1906, Apr.-May, pp. 
73. 89. 
Evans Sons Lescher and Webb point out that eucalyptol is usually 
found to contain upward of 98 per cent of cineol by weight, but that 
one sample; which came to their attention only yielded 84 per cent. —

EUCALYPTUS. 
Smith, Henry C., discusses the variety and the interesting nature 
of the constituents of the several eucalypts, and the assistance given 
by this knowledge to facilitate the botanical arrangement and the 
classification of the several species. The author discusses more par- 
ticularly the kinos or astringent exudations, oxalic acid, and the 
oils. — Yearbook of Pharmacy, 1906, pp. 295-298. (See also Pharm.

revision of the genus Eucalyptus,” by J. H. Maiden. — Semi-Ann.
