CON V ALL ARIA. 
Gienapp, E. (Wiener illustr. Gartenztg., 1905, pp. 66-70), presents 
an article on the cultivation of convallaria, the exportation of the 
plant to America, and the preservation of the young plants by means 
of ice. — Bot. Centralbl. for 1905, v. 100, p. 91. 
CORIANDRUM. 
Eberle, E. G., mentions coriander among the medicinal plants of 
Texas. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 304. 
Spaeth, E., points out that commercially satisfactory coriander 
should not yield more than 7 per cent of ash and that the portion 
insoluble in 10 per cent hydrochloric acid should not exceed 2 per 
cent. — Ztschr. f. Unters. d. Nahr. u. Genussmittel, Berlin, 1905, v. 10, 
p. 25. 
CREOSOTTJM. 
Francis, John M., points out that the tests for phenol and coal-tar 
creasote are ample; the coerulignol test is very important and the 
one most likely to be needed. — Bull. Pharm., Detroit, 1905, v. 19, 
p. 450. 
CRESOL. 
An editorial note on cresol asserts that it is “ difficult to obtain, 
of good quality, in this market.” — Drug Topics, 1905, v. 20, p. 196. 
The same assertion is contained in correspondence to H. J. Eb- 
• erle. — Am. Druggist, 1905, v. 47, p. 297. 
The Ph. Hisp., VII, requires that cresol have a specific gravity of 
approximately 1,045; that it boil at from 185 to 205° C., and be 
soluble in from 40 to 50 parts of water at ordinary temperatures, 
and freely soluble in strong alcohol, glycerin, or §ther. — Farmacopea 
Oficial Espanola, 1905, p. 231. 
An abstract (from Riedel’s Report) outlines a method for the 
approximate determination of cresols and phenols in crude cresols. — 
Year Book of Pharmacy, Lond., 1906, p. 29. 
Hallberg, C. S. N., discusses cresol and its solution. The article 
is accompanied by some additional comments brought out in dis- 
cussion. — Proc. Am. Pharm. Ass., 1905, v. 53, pp. 417-4:19. 
Adam, Paul, presents a comparative study of several formulas that 
have been proposed or are included in other pharmacopoeias. He 
proposes a simple mixture of equal parts of cresol and 30 per cent 
solution of sodium hydrate. — J. de pharm. et de chim., Paris, 1905, 
v. 22, p. 145. 
Tollens, Karl, reports a comparative study of the toxicity of cresol 
and the saponaceous preparations of cresol with similar preparations 
of phenol. The experiments lead him to conclude that a cresol soap
