ON GALBANUM.

that the last kind has a different origin from the two 
first: — 
1. The color is never greenish, but always reddish 
brown. 
2. The odor is quite characteristic. 
3. In commerce it is always more impure, and is never 
met with in grains, or in the state of Levantic galbanum. 
The debris of the stalks are different and thicker. 
4. It is procured from another country. Persian galba- 
num is always received from Astracan and Oremburg, and 
it is the kind employed in Russia. 
Levantic galbanum is imported into Trieste and Mar- 
seilles, and it has but recently been known and used in 
Russia. 
A large quantity of Levantic galbanum, which was de- 
posited for a long time in Hanover, where it was entirely 
unknown, was recognised by M. Ludwig, and it was very 
soon sold with advantage, having been found as good as 
that received from Marseilles.
