LINIMENTUM AMMONIJE. 
Beringer thinks the formula adopted by the pharmacopoeia ridicu- 
lous; there is no advantage in using the combination of alcohol and 
oleic acid over the commercial olive oil for the purpose. 
Drescher thinks lard oil should be used. — Proc. New Jersey Pharm. 
Ass., 1906, p. 110. 
LINIMENTUM CAMPHORJE. 
Hommell. P. E., thinks that camphorated oil made with cotton- 
seed oil is undesirable, especially so from a medical standpoint, as it 
lacks the emollient, penetrating, and other properties which the doctor 
desires when he exhibits this agent. He thinks the oils of olive and 
benne are more emollient and demulcent ; olive oil, too, is nondrying, 
while cotton-seed oil is so. — Proc. New Jersey Pharm. Ass., 1906, 
p. 107. 
Alpers, W. C., suggests the use of circulatory displacement in 
making liniment of camphor and outlines the method employed. — 
Proc. Am. Pharm. Ass., 1906, v. 54, p. 506. 
Evans, John, thinks it necessary to check the amount of camphor 
in the finished product ; this is easily done bv heating a known weight 
(5 gm.) of the sample in a small flat-bottomed porcelain dish over 
the water bath to constant weight. Loss of weight equals camphor. 
Another method is by determination of the specific gravity of the 
olive oil used and of the finished product; every 1 per cent of camphor 
increases the specific gravity about 0.0005. He asserts that the, prep- 
aration does not deteriorate by volatilization. — Apothecary, Boston, 
1906, v. 18, p. 906. 
Utz suggests that a method for estimating the camphor content of 
this preparation be added. — Apoth. Ztg., Berl., 1906, v. 21, p. 930. 
Liverseege, J. F., records a number of adulterations in connection 
with camphorated oil. Most of the defective samples were small 
vials put up by unqualified dealers. Several of the samples con- 
tained from 20 to 40 per cent of paraffin oil and only 5 to 7 per cent 
of camphor. — Year Book of Pharmacy, 1906, p. 269. 
LINIMENTUM SAPONIS MOLLIS. 
- 
Dunning, H. A. B., asserts that the quickest and most satisfactory 
method of making liniment of soft soap is to heat the soap for some 
time on a water bath until quite soft, then turn off the flame and dis- 
solve the soap in the requisite amount of alcohol. — Proc. Am. Pharm. 
Ass., 1906, v. 54, p. 483. 
Havenhill. L. D., reviews the history of soap liniment and the 
various changes in the official formula for this preparation, and pre- 
sents a modified formula, which he believes is designed to obviate
