The  manufacture  of  oil  of  lemon  and  citrate  of  lime  in  Sicily  is 
the  subject  of  an  exhaustive  paper  by  E.  M.  Chace  who  made  a 
personal  investigation  of  the  conditions  prevailing  in  Sicily  at  the 
time  of  his  visit.  The  article  is  illustrated  and  is  particularly  inter- 
esting at  this  time  as  being  descriptive -of  the  conditions  prevailing 
in  Sicily  before  the  recent  catastrophe  in  the  citrus  district. — Jour, 
of  Industr.  and  Eng.  Chem.,  1909,  v.  1,  p.  25. 
Lemon  Scented  Bay. — An  abstract  (from  West  Ind.  Bull:,  v.  9, 
pp.  265-276)  describes  a  variety  of  "bay"  known  as  Pigmenta 
acris  var  citrifolia  or  lemon  scented  bay,  which  yields  an  oil  that  has 
a  distinct  lemon-like  odor,  with  a  secondary  odor  resembling  that 
of  phenylisocyanide. — Pharni.  Jour.,  London,  1909,  v.  28,  p.  6. 
New  Adulterant  of  Lavender  Oil. — J.  Delphin  points  out  that 
the  esters  of  the  fatty  acids  of  cocoa-nut  oil  have  been  detected  as 
being  added  to  lavender  oil  of  poor  quality.  These  cocoa-nut  esters 
lend  themselves  well  to  this  fraudulent  application  since  the  saponi- 
fication value  is  very  high,  so  that  only  a  very  slight  addition  is 
necessary  to  greatly  "  improve  "  the  ester  value  of  the  oil. — Pharni.

Turpentine  and  its  Adulterants.— Arthur  E.  Paul  discusses  the 
production  of  turpentine  and  the  characteristics  of  the  oil  distilled 
from  it.  He  also  describes  "  wood  turpentine;"  also  known  as 
"  stump  "  turpentine,  steamed  wood  turpentine  and  wood  pulp  tur- 
pentine. As  these  products  are  but  slightly  below  turpentine  in 
price  it  follows  that  as  a  commercial  adulterant  they  would  have  to 
be  used  in  large  quantities  to  be  profitable.  Among  the  more 
common  adulterants  he  enumerates  the  several  petroleum  products 
and  turpentine  substitutes. — Jour,  of  Industr.  and  Eng.  Chem.,  1909, 
v.  1,  pp.  27-31. 
Toxicity  of  Bismuth  Subnitrate. — The  toxicity  of  this  substance 
is  discussed  by  Emil  G.  Beck,  who  reviews  the  literature  and  con- 
cludes that  bismuth  subnitrate  administered  by  stomach  in  small 
doses  is  harmless.  When  given  in  large  doses,  by  mouth,  or,  more 
particularly,  when  injected  by  rectum,  bismuth  subnitrate  may  lib- 
erate nitrites  which  may,  in  turn,  cause  poisoning. — Jour.  Am.  M. 
Assoc.,  Chicago,  1909,  v.  52,  pp.  14-18. 
Mercurous  nitrate  as  a  micro  chemical  reagent  for  arsenic  has
