Santalum album, Linne.* 



India, ascending to the temperate elevations of Mysore. A 

 small or middle-sized tree, famed for its fragrant wood and 

 roots. In the drier and stony parts of ranges the greatest 

 fragrance of the wood is generated. S. Freycenetianum 

 (Gaudichaud) produces sandal-wood on the mountains of the 

 Sandwich Islands up to 3,000 \eet. Several other species 

 occur in Polynesia. The precious sandal-oil is obtained by 

 slow distillation from the heartwood and root, the yield being 

 about two and a half per cent.

 most sensitive colours. Experiments instituted in the labo-
