VOLATILE OIL IN CRYPTOMERIA WOOD. 405 



to the cholesterins. Indeed the solution in chloroform produces 

 on the addition of some concentrated sulphuric acid a dark 

 red color. 



I propose to call it Sugiol, from sugi, the Japanese name 

 for Cryptomcria Japonica. 



Sugiol is an oil of neutral reaction, almost completely in- 

 soluble in water, but easily soluble in alcohol, ether and 

 chloroform. Its boiling point is 264 0 , spec, gravity 0.935. ^ 

 yields no crystalline acetyl and hydrazon compound, but 

 reduces alkaline silver solution very slowly in darkness.
