Hartwich, C. (Arch. d. Pharm., y. 242, p. 647), discusses the iden- 
tification of ipecac and some of its substitutes by means of the struc- 
tural characteristics shown under the microscope. — Abstr. in Proc. 
Am. Pharm. Ass., 1905, v. 53, p. 640. 
Collin, Eug., points out that for the recognition of the several 
varieties of ipecac the determination of the size of the starch granules 
and of the crystals that are present offers a ready method for dif- 
ferentiating between them. — Just’s Bot. Jahresber. for 1905, v. 33, 
part 3, p. 198 (from J. de Pharm. et de Chim., v. 20, pp. 293-300). 
Mannich and Brandt (J. de Pharm. et de Chim., v. 20, p. 276) 
report the root of Heteropteris pauciflora , mentioned by Peckolt of 
Rio, as being used to adulterate ipecac. IVhile in external appear- 
ance this root closely resembles ipecac, its histological structure is 
markedly different. It contains no starch or raphides of calcium 
oxalate but shows cells containing a peculiar brown coloring mat- 
ter. — Analyst, Lond., 1905, v. 30, p. 60. 
Vanderkleed, Charles E., reports 14 assays of ipecac which varied 
from 2.01 to 2.63 per cent of ether-soluble alkaloids. The general 
quality of this drug he believes to be very good.— Proc. Pennsyl- 
vania Pharm. Ass., 1905, p. 56. 
An abstract asserts that during the past year comparatively little 
ipecac was found that complied with the Ph. Germ., IV, requirement 
of 2.03 per cent of alkaloid. Of 19 samples examined only 3 were 
found to comply with this requirement. — Suedd. Apoth. Ztg., 1905, 
v. 45, p. 528. 
Stanislaus, I. V. S., offers some remarks on the ipecac root of the 
pharmacopoeia. — Am. Druggist, A. Y., v. 47, p. 350. 
Maben, Thomas, believes that the reduction of the standard to 
1.75 per cent of alkaloids is a mistake. It seems unwise to reduce the 
standard to what is practically the lowest strength found in com- 
merce. — Pharm. J.. Lond., 1905, v. 21, p. 141. 
Caeser and Loretz outline a method for the assay of ipecac in which 
they recommend ether as the primary solvent in place of the ether 
chloroform mixture directed by the U. S. P.. VIII. — Geschafts-Ber. 
von Caeser & Loretz, in Halle a. S., 1905, p. 93. 
Gadd and Gadd point out the necessity for examining prepara- 
tions of ipecac because of the doubt that has been cast upon the sta- 
bility particularly of the liquid preparations. — Pharm. J., Lond., 
1905, v. 21, p. 439. 
Xaylor, TV A. H., discusses the standardization of the galenical 
preparations of ipecac and the several methods of assay that have 
been proposed. — Ibid., p. 124. 
Lyons, A. B., believes that the official fluid extract of ipecac will 
find no favor with pharmacists because it is loaded with resinous
