Chili  Borates  and  Boracic  Acid. — Chili  saltpetre-caves  and 
their  surroundings  yield  a  large  percentage  of  borates  and  boracic  acid. 
C.  Reichardt  publishes  the  following  constituents  of  a  new  pulveru- 
lent Chili  mineral,  analyzed  by  him  : 
Water,  ....  18*107 
Sand  and  clay,         .  .         15  056 
Silicic  acid,        .  .  .  0*070 
Oxide  of  iron  and  aluminium,  0*840 
Lime,     ....  0*727 
Magnesium  chloride  (MgCl2),       1-109  99  84°' 
The  mineral  contains  18*594  per  cent,  of  boracic  acid. — Arch.  d. 
Pharm.,  Aug.  1878,  p.  13U . 
Salicylic  Cotton,  Benzoic  Cotton  and  Liquor  Aluminae  Ace- 
ticse  as  Antiseptics. — 5  per  cent,  salicylic  cotton  is  made,  according  to 
Prof.  Paul  Bruns,  by  saturating  1  kilo  of  cotton  with  4  liters  of  a  solu- 
tion of  50*0  grams  salicylic  acid,  20 -o  grams  castor  oil  (or  castor  oil 
and  colophony,  each  10  0  grams),  in  3*930  liters  (3930  cc.)  of  alcohol. 
10  per  cent,  salicylic  antiseptic  cotton  is  made  by  saturating  I  kilo  of 
cotton  with  a  solution  of  ioo*o  grams  salicylic  acid,  40^0  grams  castor 
oil  (or  castor  oil  and  colophony,  each  20*0  grams),  in  4*860  liters- 
(4860  cc.)  of  alcohol. 
Benzoic  cotton  is  made  in  the  same  manner,  substituting  benzoic  for 
salicylic  acid. 
Liquor  alumina  aceticce  is  considered  by  the  author  far  superior  to 
thymol,  carbolic  and  salicylic  acid,  etc.,  for  disinfecting  purposes,  for 
dressing  wounds  and  for  permanent  antiseptic  irrigation  ;  he  uses  a 
diluted  3  per  cent,  solution,  prepared  from  72*0  grams  alum,  II5'0 
grams  acetate  of  lead,  and  sufficient  water  to  make  the  filtrate  measure 
a  pint ;  this  solution  he  frequently  dilutes  with  3  to  6  times  its  bulk  of 
water. — Pharm.  Centralh.,  Sept.  26,  p.  361-362.. 
Detection  of  Organic  Poisons. — E.  Heintz  proposes  to  evaporate 
the  liquid  containing  organic  poisons  with  white  bole,  previously  treated 
with  hot  hydrochloric  acid  and  well  washed  with  water.  The  residue 
is  exhausted  with  chloroform  or  other  solvents,  and  retains  fats,  resins- 
and  other  impurities. — Zeitschr.f.  Anal.  Chem.,  1878,  p.  166.
