He  suggests  the  following  formula  for  a  clove  water,  stating 
that  it  meets  all  possible  requirements  as  a  vehicle  and  is  particu- 
larly efficient  for  the  administration  of  bromides  and  iodides. 
Oil  of  cloves    4.0  c.c. 
Tincture  of  cudbear   50.0  c.c. 
Alcohol    43-Q  c.c. 
Purified  talc   15.0  gm. 
Water  to  make    1000.0  c.c. 
Mix  and  filter.

Saffron. 
By  R.  I.  Grantham. 
Because  of  its  excessively  high  price  saffron  is  frequently  found 
on  the  market  adulterated  in  many  ways. 
Among  the  methods  practised  for  this  purpose  the  author  men- 
tions the  mixing  with  vegetable  filaments,  coloring  with  aniline 
dyes,  and  by  adding  articles  of  high  specific  gravity,  such  as  glycerin, 
molasses,  honey,  and  salts  of  sodium  and  potassium,  as  well  as 
barium  sulphate  to  increase  its  weight. 
The  author  gives  the  result  of  some  tests  on  4  samples  to  deter- 
mine the  presence  of  added  coloring  matter  of  aniline  origin.  The 
results  so  far  as  color  from  this  source  is  concerned  were  negative.

Laboratory  Notes. 
By  Thomas  A.  Egan. 
Commenting  on  the  manufacture  of  zinc  oxide  ointment  the 
author  recommends  that  the  zinc  oxide  be  triturated  in  a  mortar  with 
10  per  cent,  of  oil  of  benne  until  perfectly  smooth,  then  melt  the 
lard,  add  to  contents  of  mortar  and  stir  continuously  until  mixture 
becomes  firm.  By  this  method  an  ointment  is  obtained  which 
remains  smooth  and  does  not  become  granular  with  age. 
Discussing  the  time-honored  Basham's  mixture,  he  remarks 
that  the  varying  temperature  of  the  store  is  the  source  of  trouble 
with  this  preparation,  as  it  favors  chemical  change.  He  replaces 
part  of  the  water  used  in  making  this  preparation  with  orange  flower 
water  and  keeps  it  in  the  refrigerator.
