elude  that  phenicated  water,  in  the  proportion  of  from  1-1,000  to 
even  5-10,000,  might  be  applied  to  keep  raw  meat  fresh  and  sweety 
without  imparting  to  it  either  any  perceptible  smell  or  taste,  provided 
the  meat  be  kept  in  well-closed  vessels,  be  they  casks,  tinned  iron 
canisters,  or  other  vessels. 
Second  process :  By  m-eans  of  vegetable  charcoal  coarsely  broken 
up^  and  saturated  ivith  phenicated  water  at  from  5-10,000  to  1-1,000. 
— This  process  is  applied  as  follows  :  I  cover  the  meat  with  a  thin 
woven  fabric,  in  order  to  avoid  its  direct  contact  with  the  charcoal, 
which  might  penetrate  into  the  fibre  of  the  meat,  which  is  placed  next 
into  barrels,  care  being  taken  to  place  therein  first  a  layer  of  the 
phenicated  charcoal,  then  a  layer  of  meat,  and  so  on,  alternately, 
until  the  barrel  is  quite  filled,  and  all  interstices  properly  taken  up 
by  the  charcoal.  As  regards  the  importation  of  raw  meat,  preserved 
by  this  method,  from  South  America,  I  would  suggest  that  the  meat, 
first  covered  with  any  thinly-woven  fabric,  be  placed  in  bags  made  of 
raw  caoutchouc,  very  abundantly  obtainable  in  the  country  alluded 
to;  so  that  the  importation  of  raw  meat  and  the  importation  of 
caoutchouc  might  go,  as  it  were,  hand  in  hand.  The  mode  of  filling 
in  alternate  layers  of  phenicated  charcoal  and  meat  would,  of  course, 
remain  the  same  ;  and  there  would  be  no  difiiculty  of  hermetically 
sealing  up  bags  made  of  caoutchouc,  either  by  soldering  the  seams 
together,  or  by  placing  a  cap  of  caoutchouc  over  the  mouth  of  the 
bag,  and  soldering  the  cap  on  hermetically. —  The  Drug.  Circular

ON  THE  QUANTITATIVE  ANALYSIS  OF  WHITE  LEi^D  GROUND 
IN  LINSEED  OIL. 
By  Yictor  Biart. 
Text  books  on  chemistry  tell  us  very  little  about  adulterations  of 
paints.  Take,  for  instance,  white  lead ;  how  shall  we  proceed  ?  If 
the  druggist  bought  it  in  the  state  of  powder,  it  would  be  relatively 
easy ;  but  as  it  is  generally  sold  ground  in  linseed  oil,  the  case  ap- 
pears to  be  more  complicated.  If  we  refer  to  books,  it  will  general- 
ly be  with  disappointment. 
As  an  instance,  I  give  what  I  found  in  a  good  book  on  chemistry, 
in  the  part  of  the  work  relating  to  chemical  analysis,  speaking  of  the 
analysis  of  white  lead  in  oil,  the  author  says :    "  When  the  white
