It may be well to direct attention to the danger of a mixed 
compound, when preparing these substances. The plates of the 
second body mentioned in the former paper evidently consisted of 
such, and contained enough “eudesmin” to alter the melting point 
as they gave a melting point of 162°C. Later a purer product 
of Aromadendrin was obtained from the kino of EZ. hemiphloia 
which melted at 192° C., while the melting point of pure Aroma- 
dendrin is 216° C. 
Aromadendrin is readily soluble in ether, acetic ether, rectified 
spirit, and amyl alcohol ; but is almost insoluble in chloroform. 
It is insoluble in benzole and petroleum spirit. When dissolved
