matter, and so can not be mixed directly with syrup to make the 
official syrup of ipecac. — Proc. Am. Pharm. Ass., 1905, v. 53, p. 258. 
JALAP A. 
Eberle, E. G., says that Jatropha macrorhiza has a large globular 
rhizome having emetic and purgative properties. It is kept in drug 
stores along the Mexican border and is known as jalapa. — Proc. Am. 
Pharm. Ass., 1905, v. 53, p. 306. , 
Maben, Thomas, points out that the curious fall in the resin con- 
tent of jalap has been experienced in the United States as well as in 
England, and the U. S. P.. VIII, standard has been modified accord- 
ingly. As Umney has pointed out. pharmacopceial standards have 
varied from 18 to T per cent. — Pharm. J.. Lond., 1905, v. 21, p. 141. 
Vanderkleed, Charles E., reports assays of jalap which varied from 
0.48 to 8.2 per cent of resin. The general quality of this drug he 
asserts is poor. — Proc. Pennsylvania Pharm. Ass., 1905, v. 56. 
Dohme, A. K. L., asserts that jalap root is getting poorer and 
poorer/ and it is now almost impossible to get any jalap root that will 
pass the U. S. P. standard. The laboratory report indicates that the 
quality has decreased steadily from 1899, when the average resin 
content was 11.21 per cent, to 1905, when the average is but 6.2 per 
cent. — Apothecary, Boston, 1905, v. IT, p. 942. 
Gane, E. H., reports on 1,000 pounds of jalap, which yielded an 
average of 8 per cent of resin. — Proc. Am. Pharm. Ass., 1905, v. 53, 
p. 185. 
Gehe & Co. report that the bulk of the available jalap in the spring 
of 1905 consists of small immature tubers containing barely 7 per 
cent of resin. — Gehe & Co., Handels-Ber., 1905, p. 50. 
Moore, Russell W., believes that the lowering of the standard in 
the U. S. P., VIII, appears to be fully justified by the condition of 
the market. He reports the average resin content of the drug ex- 
amined in 1904 and since that time, and ventures the suggestion that 
evidently little care is exercised by the gatherers of this drug. — Proc. 
Am. Pharm. Ass., 1905, v. 53, p. 266. 
Caeser and Loretz recommend extracting the powder with abso- 
lute alcohol, heated in connection with a reflux condenser. An 
aliquot part of the resulting solution is partially evaporated and 
then treated with water. The resulting resin is dried and weighed. — 
Pharm. Ztg.. Berlin, 1905, v. 50, p. 773. 
Gadd and Gadd outline a method for determining the extractive 
present in tincture of jalap. — Pharm. J., Lond., 1905, v. 21, p. 439. 
KAOLINUM. 
Schimpf, Henry W., commends the inclusion of kaolin in the 
U. S. P., VIII, and points out some of the uses to which it may be 
put. — Am. J. Pharm., 1905, v. 77, p. 516.
