Sulphoricinate  of  sodium. — A.  Berlioz  prepares  this  salt  as  follows  : 
To  one  kgm.  of  castor  oil,  250  gm.  of  pure  sulphuric  acid  of  66° 
B.  are  added  in  small  quantities  and  with  constant  stirring,  to  avoid 
any  rise  in  temperature.  Stand  aside  for  12  hours  and  add  1,500 
gm.  cold  water;  agitate  and  remove  the  aqueous  layer,  which 
gradually  separates.  Then  to  remove  excess  of  sulphuric  acid,  wash 
a  number  of  times  with  water,  which  contains  100  gm.  of  table  salt 
per  litre,  and  which  has  previously  been  heated  to  60-700  C.  Care- 
fully add,  under  constant  stirring,  soda  lye  to  a  feebly  acid  reaction ; 
let  stand  for  two  or  three  days,  decant  and  filter. 
Sulphoricinate d  phenol,  used  for  the  treatment  of  diphtheria  (see 
Amer.  Jour.  Pharm,  1 891,  p.  195)  and  prepared  with  sodium  sulpho- 
ricinate, made  in  the  manner  indicated,  will  retain  its  transparency 
at  ordinary  temperatures. — Jour,  de  Pharm.,  Jan.,  1893,  p.  10. 
The  action  of  sulphuric  acid  on  citrene  has  been  studied  by  G.. 
Bouchardat  and  J.  Lafont  (Jour.  Pharm.  et  Chim.,  Jan.,  1893,  p.  49),. 
who  find  that  thereby  inactive  polymers  of  this  hydrocarbon  are 
formed,  the  most  abundant  of  which  is  diterpilene  C20H32.  The 
action  of  sulphuric  acid  on  the  camphenes  appears  to  give  entirely 
different  results  from  those  which  the  authors  obtained  with  biva- 
lent citrene,  and  with  monovalent  terebenthene.
