Liquor  Ferri  Chloridi. — A  specimen  prepared  by  Rob.  W.  Maris, 
Ph.G.,  had  the  specific  gravity  1-435,  contained  a  trace  of  nitric  acid, 
and  on  evaporation  10  gm.  yielded  a  solid  residue  of  1-98  gm.  Five 
commercial  specimens  contained  also  a  little  nitric  acid  (with  the 
exception  of  one  specimen)  and  gave  the  following  results: 
Specific  gravity,  i'392       1*421       1*414       i'4i7  1*406

For  the  Preparation  of  Antiseptic  Ligatures,  Edward  Q.  Thorn- 
ton, Ph.G  ,  uses  cat-gut  (E  and  A  violin  strings  being  most  frequently 
used)  which  is  wrapped  loosely  upon  glass  spools  and  then  kept  in 
ether  for  24  hours.  Remove  the  spools  from  the  ether,  pass  a  glass 
rod  through  them,  and  allow  the  ether  to  evaporate  avoiding  con- 
tact with  anything.  When  dry  cover  with  a  one  per  cent,  solution  of 
mercuric  chloride  in  diluted  alcohol;  after  half  an  hour  remove  from 
the  mercuric  solution,  and  wipe  the  cat-gut  with  a  towel  that  had 
previously  been  washed  out  of  a  01  per  cent,  solution  of  mercuric 
chloride  in  water.  The  cat-gut  is  preserved  in  a  bottle  under  oil  of 
juniper,  and  should  remain  in  the  oil  for  at  least  ten  days  before  it 
is  used.    (See  also  American  Journal  of  Pharmacy,  1886,  p.  598.) 
Preservation  of  Yolk  of  Egg. — Cyrill  D.  Rosenkrans,  Ph.G., 
recommends  the  preservation  of  the  yolk  by  carefully  drying  it  upon 
glass  plates,  and  keeping  it  in  thin  layers  in  paper  boxes  lined  with 
paraffined  paper.  After  several  months  it  showed  no  tendency  to 
rancidity  or  decomposition.  Using  this  dried  yolk  for  an  emulsion, 
it  is  rubbed  up  in  a  mortar  with  a  small  quantity  of  sugar,  then 
sufficient  water  is  added  to  make  a  smooth  paste,  after  which  the  oil 
and  remaining  water  are  incorporated  with  it  in  the  usual  manner. 
1NoT;K  by  The;  Editor. — The  French  Codex  gives  a  formula  for  Phenol  sodi 
dissous,  which  consists  of  phenol,  70  gm.*  caustic  soda  solution  (spec.  grav. 
1*332),  100  gm. ;  distilled  water  sufficient  to  make  one  liter.  The  soda  solution 
contains  nearly  23  gm.  of  Na20  corresponding  to  29  gm.  of  NaHO.
