Smith, Kline & French Company point out that the most common 
adulterant of cloves is clove stems. They report the following data for 
Zanzibar cloves: Ash, 5.36 per cent; ash insoluble in hydrochloric 
acid, 0.12 per cent; crude fiber, 7.5 per cent. — Lab. Rep. S. K. & F., 
1906, p. 34. 
Utz suggests that for cloves the ash content should not exceed 10 
per cent, and the drug should contain at least 10 per cent of volatile 
oil. — Apoth. Ztg., Berl., 1906, v. 21, p. 930. 
Sprinkmeyer and Fiirstenberg found the sand free ash in cloves to 
vary from 0.52 to 7.02 per cent. — Ztschr. f. Unters. d. Nahr. u. 
Genussm., 1906, v. 12, p. 657. 
Thamm, R., found the sand free ash in cloves to vary from 6.29 to 
6.82 per cent ; also discusses the composition of the ash, its solubility 
in water and its alkalinity. — Ibid., v. 12, p. 168. 
Rusby, H. H., asserts that clove stems are sold for cloves. — Proc. 
Am. Pharm. Ass., 1906, v. 54, p. 335. 
Fernan, Albert, reports finding a sample of partially extracted 
cloves containing but 1.5 per cent of eugenol. — Ztschr. d. allg. osterr. 
Apoth. -Ver., 1906, v. 44, p. 79. 
The fifth report of the Illinois Food Commission says that of 84 
samples of cloves examined, 4 were inferior, 23 contaminated, and 24 
adulterated with clove stems, cassia, ginger, sand, flour, pepper, shell, 
or allspice. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 335. 
CATAPLASMA KAOLINI. 
Cook, E. Fullerton, reports that Herbert L. Flack, as a result of 
his experiments and investigations, recommends the addition of about 
5 per cent more of glycerin to the U. S. P. formula, and heating with 
occasional stirring during at least four hours, otherwise a slow effer- 
vescence occurs in many samples which renders the product unfit to 
dispense in tight cans. — Am. J. Pharm., Phila., 1906, v. 78, p. 419. 
Hemm, Francis, exhibited two samples, one like a fluid and the 
other satisfactory. In the one case the clay used had lost 1 gramme 
in 5 on heating, 400 grammes mixed with the full amount of glycerin 
intended for 500 made it too soft. Hemm heats the clay for two 
hours, instead of one, as directed by the U. S. P. — Proc. Missouri 
Pharm. Ass., 1906, p. 46. 
Schultze thinks that from 2 to 3 per cent more glycerin should be 
added to the formula. — Proc. Maryland Pharm. Ass., 1906, p. 94. 
Dunning concurs ; thinks the difficulty due to the great difference in 
the kaolins on the market. — Ibid., p. 97. 
Stevens, A. B. (Bull. Pharm., Aug., 1906, 346), asserts that the 
U. S. P. formula for making cataplasm of kaolin is all right, and that
