in whole or in part, of its essential oil, and has a strong characteristic 
odor and taste. The maximum amount of ash, for the air dry drug, 
should not exceed 8 per cent, and the amount insoluble in 10 per 
cent hydrochloric acid should not exceed 2 per cent. — Ztschr. f.

CARYOPHYLLTJS. 
LalYall, Charles H., reports finding ground clove containing wheat 
starch. — Proc. Am. Pharm. Ass., v. 58, 1905, p. 18. 
Gadd, H. Wippell, points out that the admixture of exhausted 
flower buds is easily detected by fixing the clove, head downward, on 
the point of a drawing pin and applying a match to the stalk. Good 
specimens burn readily. — Pharm. J., Lond., 1905, v. 21, p. 902. 
Spaeth, E., points out that among the more common adulterants 
of this drug are cloves deprived of their oil, clove stems, and cacao 
shells. The total absence of starch should not be insisted on, but 
the starch present should be defined as that of the mother clove, 
which is occasionally present. The starch of ginger should not be 
present. Commercially satisfactory cloves should be undamaged and 
consist of the complete flower buds that have not been deprived, 
either in whole or in part, of their essential oil, and have a strong 
odor and taste of eugenol. Powdered cloves should be brown-red or 
brown in color and should possess a strong characteristic odor and 
taste. The presence of clove stems should not exceed 10 per cent and 
the amount of essential oil present should be at least 10 per cent. 
The total ash should not exceed 8 per cent and the amount insoluble 
in 10 per cent hydrochloric acid should not exceed 1 per cent. —

Herzog, J., presents a preliminary publication on caryophyllin. — 
Ber. d. pharm. Gesellsch., Berlin, 1905, v. 15, p. 121. 
Meyer and Honigschmidt (Monatsh., 1905, v. 26, pp. 379-389) 
discuss the source and character of caryophyllin. — J. Chem. Soc., 
Bond., 1905, v. 88, Pt. II, p. 456. 
CATAPLASMA KAOLINI. 
Schimpf, Henry W., in discussing the cataplasm of kaolin, says : 
This is similar to certain proprietary clay preparations. It is undoubtedly 
a very useful preparation and not an entirely novel one, for the peasants of 
central Europe have long employed a mixture of clay and glycerin as a house- 
hold remedy for many ailments, especially where poultices were indicated. — 
Am. J. Pharm., Phila., 1905, v. 77, p. 516. 
An editorial expresses the view that — 
the introduction of this article comes as a surprise, as the use of these clay 
poultices has occasioned much criticism and is by some considered as a distinct
