Viewed through spectroscope, produces nn absorption of whole spectrum, but ii., 

 absorption bands. It is possible, from the colour apparently ( nmencing formation 

 in the sap wood, from its solubilities and insolubilities, that it may be a result df 

 the decomposition of the balsam in the outer layer of the woody tissue. As poon 

 as a larger supply of the wood can l)o obtained an inquiry into the compositiou 

 and origin of these colours Avill be made.
