About eight years ago the firm Schimmel & Co. (Fritzsche 
Bros.), of Leipzig, manufacturers of volatile oils, commissioned 
Messrs. E. Gildemeister, of Leipzig, and Fr. Hoffmann, of Berlin, 
with the preparation of a treatise on the entire subject of volatile 
oils. The result was a volume of over 900 pages (with maps an.l 
numerous illustrations, which, under the title " !)/'■ athen^en 
Ole," was published by Julius Springer, of Berlin, in 18'J. 1 . In the 
following year it appeared in a slightly comb-n.- 
Volatile Oils, 732 pages), translated by Edw. Kremers. or Alison, 
Wisconsin, and published by the Pharmaceutical Keview tui- 
Hshing Co., of Milwaukee. The work is a remarkable and 
unfortunately all too rare instance of co-operation between prac- 
tical and scientific men. In plan and execution it gives sinking 
proof of the farsightedness and liberality of the man 
who wished to see their business placed on a scientific basis, and 
at the same time of the thoroughness of the experts who were 
invited to carry out the ideas of their commissioners. The pan 
dealing with the " Oils of the Gramineae " occupies pp. iW-JM) oi
