ANALYSIS  OP  RED   SANDAL  WOOD. 
dissolved  in  hydro-chloric  acid,  the  solution  accurately  saturated 
with  ammonia  and  divided  into  several  portions. 
Chloride  of  calcium  indicated  oxalic  acid.  Sulphate  of  mag- 
nesia and  ammonia  indicated  phosphoric  acid,  oxalate  of  ammo- 
nia indicated  lime,  and  the  liquid  filtered  from  the  oxalate  of 
lime  gave  with  ammonia  a  precipitate  of  magnesia. 
By  subsequent  quantitative  experiments  the  author  deter- 
mined the  proportion  of  these  salts  in  1675  parts  to  be  50  parts 
of  oxalate  of  lime,  20  parts  of  phosphate  of  lime  and  30  parts 
of  phosphate  of  magnesia,  with  about  five  parts  of  coloring 
matter  left  by  the  alcohol. 
Action  of  fire  on  sandal  wood  exhausted  by  water  alcohol  and 
hydrochloric  acid. — The  wood  exhausted  by  the  three  preceding 
processes  was  decomposed  and  gave  the  ordinary  products  of 
the  distillation  of  wood,  and  an  ash  :  1570  parts  of  the  wood 
gave  29  of  ash,  consisting  of  silica  and  carbonate  of  lime ,  the 
parts  destroyed  by  the  fire  amounting  to  1541  parts  of  lignin. 
It  results  from  the  preceding  experiments  that  sandal  wood  has 
the  following  complex  composition,  viz: 
100  parts  of  the  wood  contain  :
