Kahn, Joseph, points out that citric acid is sometimes adulterated 
with tartaric acid, and outlines several readily applied tests for de- 
tecting the latter. — Am. Druggist, X. Y., 1906, v. 49, p. 6. 
Ohliger. Willard, reports citric acid with traces of tartaric acid 
and solubility in alcohol not U. S. P. — Proc. Michigan Pharm. Ass., 
1906, p. 46. 
Kebler, Lyman F., reports citric acid that contained lead and trace 
of sulphate. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 348. 
Macfadden, A. W. J. (Local. Govt. Bd. [Gt. Brit.], Med. Dept., 
Bpts. Insp. Foods, 1906, Xo. 2, p. 10), reports on a large number of 
samples of citric acid. Small quantities of lead were found in nearly 
every sample and very small quantities or traces of arsenic in a num- 
ber of samples, these metals being accidental impurities. — Exper. 
Sta. Bee., 1906, v. 18, p. 1149. 
Evans Sons, Lescher & Webb point out that citric acid is, as a rule, 
free from adulterations, and assert that the examination of a large 
number of samples revealed only one case in which the lead reached 
0.002 per cent, a great majority containing 0.001 per cent and under, 
and that in all cases the quantity of arsenium has proved to be below 
one part per million. — Analytical Xotes for 1906, 1907, p. 13. 
ACIDUM CITRJCUM SACCHARATUM N. F. 
Caldwell, Paul, doubts the practicability of saccharated citric acid 
and its companions elsewhere in the X. F. Ill, and says “ it is hardly 
possible to carry them in stock without fear of deterioration.” — Drug. 
Circ. & Chem. Gaz., X. Y., 1906, v. 50. p. 392. 
ACIDUM GALLICUM. 
The Ph. Brit. Committee of Reference in Pharmacy points out 
that the tartarated-antimony statement, in connection with gallic 
acid, is incorrect. — Chem. & Drug., Loud., 1906, v. 69, p. 862. 
ACIDUM GLYCEROPHOSPHORICUM N. N. R. 
Alpers, W. C., points out that with the preparation of glycerophos- 
phates sterilized water only should be used. His experience had been 
that when dissolved in ordinary water glycerophosphates rapidly 
deteriorate. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 487. 
Dunning, H. A. B., discusses the glycerophosphates and presents 
a tried formula for the compound elixir, which can be used for the 
plain elixir also. — Bull. Pharm., Detroit, 1906, v. 20, pp. 157-159. 
The writer presents further remarks and formulas. — Ibid., pp. 
214, 245. 
Patch, E. L., reports that sodium glycerophosphate is sometimes 
acid and sometimes alkaline ; varies from 1.4 per cent H 3 P0 4 to 0.175 
per cent XaOH. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 346.
