  ON 
  THE 
  PRODUCTS 
  OF 
  THE 
  

  

  cent., 
  and 
  which 
  were 
  obviously 
  mixtures 
  of 
  the 
  picoline 
  and 
  lutidine 
  salts. 
  When 
  

   the 
  last 
  mother 
  liquor, 
  however, 
  was 
  evaporated 
  to 
  a 
  small 
  bulk, 
  and 
  alcohol 
  and 
  

   ether 
  added, 
  another 
  salt 
  altogether 
  distinct 
  from 
  that 
  of 
  picoline, 
  and 
  crystal- 
  

   lizing 
  in 
  flattened 
  tables, 
  was 
  deposited, 
  which 
  analysis 
  proved 
  to 
  have 
  the 
  con- 
  

   stitution 
  of 
  the 
  lutidine 
  salt. 
  

  

  This 
  platinum 
  salt 
  crystallizes 
  from 
  its 
  solutions 
  in 
  square 
  tables, 
  sometimes 
  

   very 
  distinct, 
  at 
  other 
  times 
  confused 
  and 
  irregular. 
  It 
  dissolves 
  very 
  readily 
  

   in 
  cold 
  water, 
  and 
  still 
  more 
  abundantly 
  in 
  boiling, 
  and 
  appears 
  also 
  to 
  be 
  very 
  

   easily 
  soluble 
  in 
  excess 
  of 
  hydrochloric 
  acid. 
  Numerous 
  analyses 
  of 
  this 
  salt 
  

   were 
  made, 
  of 
  which 
  the 
  following 
  are 
  the 
  results 
  :
