_ with black veins; thin shavings appear blood red with veins of

naked eye; all parts of the wood are full of colouring matter. 
> Chemical composition.—Red sandalwood was first examined - 
L. Meier, who obtained from it a red crystalline principle to 
which he gave the name of Santaline. Meier obtained this 
bstance by exhausting the wood with ether, the extract thus 
tained was then washed with water, dissolved in alcohol, and — 
e alcoholic solution precipitated by acetate of lead, on. the. . 
removal of the lead the liquid yielded the santaline. . - as

Weidel (1870) exhausted the wood with we water con- 
aining a littlé potash and obtained by means of hydrochloric
