VOLATILE OILS. 
An editorial expresses the belief that it is premature for methods 
of assay to be placed in the pharmacopoeia which can be properly 
carried out only by skilled analysts and which are of so recent a date 
that few pharmacists in the retail business have ever heard of them, 
least of all tried them practically. — Drug Topics, N. Y., 1905, v. 20, 
p. 215. 
Umney and Bennett assert that — 
Viewed all around, there can be no question that the monographs are in them- 
selves models of what such monographs intended for guidance in medicine 
should be. and in our opinion they go very decidedly further and are likely to 
be of value to all manufacturing pharmacists, also to those handling essential 
oils, and record the principal features in a concise form for judging. — Pharm. 
J., Lond., 1905, v. 21, p. 143.
