Caspari, Chas., jr., calls attention to the need for care in connection 
with aromatic waters and the possibility of precipitation or separa- 
tion at low temperature. — Proc. Am. Pharm. Ass., 1906, v. 54, p. 261. 
Glass, IV. S., discusses the official aromatic waters and strongly 
urges their preparation by dissolving the respective oils, by agita- 
tion. in hot water and filtering when cold through double well-wetted 
filtering paper. — Pharm. J., Bond., 1906, v. 22, pp. 344-345. 
Hill, J. Rutherford, calls attention to the possibly dangerous incom- 
patibility of medicated waters, made by using magnesium carbonate 
as the clarifying agent, and alkaloidal salts like strychnine hydro- 
chloride. — Ibid., v. 22, pp. 224-225. 
Dunning discusses the presence of alkali in aromatic waters and 
thinks it will be avoided by following the methods of the U. S. P. 
VIII. — Proc. Maryland Pharm. Ass., 1906, p. 62. 
Dunning, H. A. B., recommends the use of powdered paper as a 
vehicle for distributing the oil in making medicated waters. He 
asserts that the solution of the oil filters off perfect^ clear and will 
be found to be highly flavored. — Proc. Am. Pharm. Ass., 1906, v. 54,

Bougault, J., wonders how many pharmacists are able to profit by 
the latitude given them as to the method of preparation of aromatic 
waters. — J. de pharm. et de chim. Par., 1906, v. 23, p. 287. 
Cook, E. Fullerton, reports that Franklin IV. Earl, after experi- 
ments with the official, U. S. P. VIII and Ph. Brit., processes for 
the preparation of aromatic waters, concludes that the hot water 
agitation method is the best, in that the water does not change on 
keeping and the process produces a saturated solution which is clear 
and requires less time for preparation. Cinnamon water can not be 
made by this method, however, as a turbid liquid results at once 
which will not clear. With purified talc, he found difficulty in free- 
ing the water from the fine suspended particles which can not be 
filtered out. Paper pulp is unpleasant to handle and does not seem 
to yield as strong a solution. Distillation invariably yields a super- 
saturated milky liquid which must be filtered. The flavor, when clis-
