made  a  similar  one.  I  heartily  second  his  suggestion,  with  the 
proviso  that  the  American  Pharmaceutical  Association  erect  the 
building  and  turn  it  over  to  the  government  on  co?idition  that  the 
U.  S.  Government  pledge  itself  to  properly  support  it.  The  co-opera- 
tion of  the  government  seems  to  me  of  the  greatest  importance.

WEST  INDIAN  SANDAL  OIL. 
The  plant  Amyris  balsamifera  yields  ah  oil  entering  commerce  as 
named  above.  This  oil  has  specific  gravity  -962,  is  dextrogyre  and 
fractionates  with  six  portions,  the  first  fraction  distilling  in  vacuo  at 
I39°-I47°  C.  and  the  sixth  at  1700 -174°  C.  The  second  and 
fourth  fractions  are  most  abundant,  and  the  two  analyze  to  C15H24  and 
C^H^HoO  respectively.  The  oil  yields  with  halogen  acids  a  series 
of  derivatives,  the  chlorine  derivative  (yield  17  per  cent.)  being 
identical  with  cadinene  dihydrochloride,  C15H242HCl,  and  the  other 
halogen  derivatives  being  analogous  cadinene  compounds. — E.  Daus-

SANDALWOOD  OIL. 
The  oil  of  Santalum  album,  examined  by  M.  Guerbet  (J.  de  Ph. 
et  Ch.y  1900,  225),  has  specific  gravity  0-9867  and  had  specific  rotat- 
ing power —  2i-i6°.  Saponification  separated  from  it  3  percent, 
of  the  following  acids :  Formic,  acetic,  santalic  and  teresantalic,  all 
found  in  the  oils  as  esters.  Santalic  acid,  C15H2402,  is  a  viscid,  color- 
less liquid  boiling  at  2io°-2i2°  C.  under  20  millimetres  pressure, 
insoluble  in  water,  but  soluble  in  alcohol,  and  is  so  feebly  acid  that 
it  can  be  freed  from  its  salts  by  C02.  Teresantalic  acid,  C10H14O2, 
occurs  in  large  colorless  prismatic  crystals  melting  at  15 7°  C,  and 
forms  crystalline  salts.  The  unsaponifiable  portion  of  the  oil 
yielded,  on  repeated  fractional  distillation,  6  per  cent,  of  sesquiter- 
penes, santalenes  a  and  /?  respectively,  the  former  boiling  at  25 2° 
C,  the  latter  at  28 1°.  Both  are  lsevogyre.  Also  two  alcohols,  san- 
talol  a  and  /9,  80  per  cent.,  the  study  of  which  is  not  complete. 
Lastly,  there  was  obtained  from  the  oil  by  precipitation  with  semi- 
carbazid  hydrochlorate  3  per  cent,  of  an  aldehyde,  santalol,  C15H240, 
a  colorless  liquid  of  peppery  odor,  boiling  at  1800  C.  under  40
