be increased to double that of the bleaching powder, as the quantity 
ordered in the present pharmacopoeia is too small to precipitate all 
the lime ; the volume should be increased as in the U. S. P. — Chem. & 
Drug., Lond., 1906, v. 69, p. 758. (See also a further note by “Able 
Scholar.” ibid., p. 803.) 
LIQUOR SODII PHOSPHATIS COMPOSITUS. 
Francis, John M., says the Committee of Revision has followed in 
the lead of the manufacturing pharmacists, in this instance, through 
whose efforts concentrated solution of sodium phosphate has attained 
a large consumption of late years. * * * A good quality of 
sodium is essential. — Bull. Pharm., Detroit, 1906, v. 20, p. 98. 
Arny, H. V., thinks this “ a rather belated recognition of " an old 
friend, exploited far more largely ten years since than it is to-day. — 
Am. J. Pharm., Phila., 1906, v. 78, p. 10. 
Dunning, H. A. B., asserts that the compound solution of sodium 
phosphate, U. S. P., when made strictly according to pharmacopceial 
directions, deposits crystals on standing. If the amount of citric acid 
is increased to 200 gm. for each 1,000 c. c. of finished preparation the 
solution is permanent. The U. S. P. directions to. triturate the salts 
are tedious and superfluous, as solution may readily be effected at a 
low temperature on a water bath. — Proc. Am. Pharm. Ass., 1906, 
v. 54, p. 485. 
Eliel. Leo, finds the U. S. P. formula unsatisfactory. The solution 
when first made is apparently perfect, but after standing for a few 
days crystals of sodium phosphate will be plentiful on bottom of 
container. A better working formula is desirable. — Proc. Indiana 
Pharm. Ass., 1906, p. 69. 
In the discussion on his paper, Eliel asserted that the manufac- 
turers do one of two things, or both; they either do not put into the 
product the amount of sodium phosphate which the label calls for, 
or they add phosphoric acid, which the U. S. P. does not call for. — 
Ibid., p. 72. 
A sample, the label of which claimed 70 grains of sodium phos- 
phate to the drachm, proved on rough analysis to contain but 35 
grains. — Ibid., p. 98. 
Robinson, Frank P., presents a formula for a palatable concen- 
trated solution of sodium phosphate, containing tincture of fresh 
lemon peel and phosphoric acid. — Bull. Pharm., Detroit, 1906, v. 20, 
p. 155. 
LITHII BROMIDUM. 
Caspari, Chas. E. 5 reports 6 samples examined. Three contained 
less lithium bromide than the U. S. P. demands, 3 contained metallic 
impurities. — Proc. Missouri Pharm. Ass., 1906, p. 100.
