ELIXIR jGrUARANE N. F. 
Caldwell, Paul, asserts that alcohol should replace the aromatic 
elixir in the formula for elixir of guar ana on account of the resinous 
nature of the fluid extract. — Drug. Circ. & Chem. Gaz., N. Y., 1906, 
v. 50, p. 392.

ELIXIR HYPOPHOSPHITUM CUM FERRO N. F. 
Caldwell, Paul, points out that in the formula for elixir of hypo- 
phosphites with iron the ferrous sulphate could be easily replaced 
by the hypophosphite and the solution effected by the addition of 
sufficient potassium or sodium citrate. — Drug. Circ. & Chem. Gaz., 
X. Y., 1906, v. 50, p. 392. 
ELIXIR PEPSINI N. F. 
Caldwell, Paul, asserts that the addition off hydrochloric acid to 
the formula for elixir of pepsin is not necessary. — Drug. Circ. & 
Chem. Gaz., X. Y., 1906, v. 50, p. 392. 
ELIXIR PEPSINI ET BISMUTHI N. F. 
Caldwell, Paul, believes that in the making of elixir of pepsin and 
bismuth a solution of pepsin in water, together with an equal amount 
of glycerin, as required in the glycerite of pepsin, is far better than 
using the glycerite itself, as the acid present tends to precipitate the 
bismuth. — Drug. Circ. & Chem. Gaz., X. Y., 1906, v. 50, p. 392. 
ELIXIR PEPSINI, BISMUTHI ET ‘STRYCHNINE N. F. 
Caldwell, Paul, asserts that the tartaric acid in the formula for 
elixir of pepsin, bismuth, and strychnine is objectionable. He sug- 
gests the use of strychnine sulphate dissolved in hot water. — Drug. 
Circ. & Chem. Gaz., X. Y., 1906, v. 50, p. 392. 
ELIXIR POTASSII BROMIDI N. F. 
Caldwell, Paul, points out that tincture of cudbear does not 
color alkaline solutions well, and that cochineal color, X. F., would 
be a much more desirable coloring agent for elixir of potassium bro- 
mide. — Drug. Circ. & Chem. Gaz., X. Y., 1906, v. 50, p. 393. 
ELIXIR QUININE ET PHOSPHATUM COMPOSITUM N. F. 
F. S. H. asserts that no possible manipulation that he knows of 
will make a permanent preparation of the elixir of quinine and phos- 
phates compound X. F. Ill, since the soluble ferric phosphate can 
not remain in solution if the finished preparation is very acid, as it 
necessarily will be from the syrup of calcium lactophosphate. On
