Reactions  of  Fixed  Oils. — Thos.  Maben  (Phar.  Jour,  and  Trans., 
March  20,  1886,  pp.  797-800}  obtained  from  the  Indian  collection  at 
the  Forestry  Exhibition  in  Edinburgh,  samples  of  the  oils  of  apricot 
(Primus  Armeniaca),  peach  (Prunus  Persica)  and  walnut  (juglans 
regia),  and  compared  their  reactions  with  those  of  oil  of  almond.  The 
test  with  nitric  acid  was  applied  by  shaking  vigorously  together  two 
fluid  drachms  each  of  the  oil  and  pure  nitric  acid,  sp.  gr.  1.42,  and 
noting  the  color  at  the  end  of  five  minutes,  an  hour,  and  five  hours. 
For  the  sulphuric  acid  test,  10  drops  of  the  oil  are  placed  on  a  white 
tile,  and  2  drops  of  strong  sulphuric  acid  are  dropped  in  the  centre  of 
the  oil.  The  chloride  of  zinc  test  is  applied  in  the  same  manner,  but 
5  drops  of  the  reagent  are  used,  and  this  is  prepared  by  making  a 
saturated  solution  of  oxide  of  zinc  in  strong  hydrochloric  acid.  In 
the  following  table,  walnut  oil  alone  is  a  drying  oil.

Products  of  Maize  — A  brief  notice  was  given  in  this  Journal,  1885, 
page  404,  of  a  process  elaborated  by  Dr.  F.  V.  Greene,  U.  S  X.,  for 
extracting  the  oil  and  albuminoid  matter  from  corn.  The  Franklin 
Institute  has  recently  awarded  the  John  Scott  Legacy  Medal  for  this 
process,  by  which  the  waste  products  of  starch  works  and  other  indus- 
tries may  be  utilized.
