4-  5-05  ;  saponification  equivalent,  3-80  ;  saponification  equivalent, 
after  acetylization,  30  3.  The  greater  portion  of  the  oil  distilled 
between  250°  C.  and  263 0  C.  Ten  volumes  of  official  alcohol  were 
required  for  solution  at  25 0  C.  The  oil  evidently  consists  chiefly 
of  a  terpene,  with  a  small  proportion  of  an  alcohol  (about  7  per  cent.), 
and  a  still  smaller  amount  of  an  ester. 
Progress  in  the  Synthesis  of  Adrenalin. 
By  Joseph  L.  Turner. 
The  paper  embodied  a  review  of  research  on  adrenalin,  its  chem- 
ical constitution,  and  attempts  to  produce  it  synthetically.  The 
author  has,  in  conjunction  with  C.  E.  Vanderkleed,  accomplished 
a  synthesis  of  adrenalin  along  lines  entirely  different  from  those 
thus  far  recorded.    The  method  was  not  given. 
The  Synthesis  of  Camphor. 
By  A.  R.  L.  Dohme. 
The  author  considered  the  reasons  for  endeavoring  to  synthesize 
camphor  and  the  advantage  of  the  same  to  the  public.  The  labor- 
atory of  Professor  Behal,  his  personality  and  method  of  work,  were 
described,  and  attention  called  to  the  advance  of  French  chemists 
over  American  from  the  standpoint  of  benefit  to  humanity  as  against 
benefit  to  science.  The  history  of  the  synthesis  of  camphor  and 
details  of  leading  methods  were  given.  Behal's  method  of  synthesis 
was  described  and  its  advantages  pointed  out. 
The  Production  of  Camphor. 
By  A.  R.  L.  Dohme. 
The  author  stated  that  about  80  per  cent,  of  the  camphor  on  the 
market  comes  from  Japan,  while  China  supplies  but  20  per  cent. 
He  said  that  the  island  of  Formosa  furnishes  the  larger  proportion 
of  Japanese  camphor,  but  it  is  difficult  to  obtain,  depending  upon 
the  fact  that  the  region  where  the  trees  grow  is  sickly  and  the 
natives  are  savage.  The  principal  refinery  of  the  Chinese  is  at 
Foochow.  Both  China  and  Japan  have  taken  measures  to  protect 
the  camphor  industry,  China  having  passed  a  law  that  for  every 
tree  cut  down,  five  shall  be  planted  in  its  place.  Japan  is  also  plant- 
ing trees,  and  has  passed  a  law  that  no  trees  less  than  fifty  years
