  The

  the 
  acid 
  is, 
  therefore,

  and 
  this 
  has 
  been 
  confirmed 
  

   by 
  the 
  analysis 
  of 
  its 
  silver 
  salt, 
  to 
  be 
  given 
  below. 
  Its 
  derivation 
  from 
  cotarnine 
  

   cannot 
  be 
  distinctly 
  understood, 
  and 
  is 
  attended 
  by 
  the 
  formation 
  of 
  several 
  other 
  

   substances 
  which 
  I 
  have 
  not 
  examined. 
  If 
  we 
  compare 
  its 
  formula 
  with 
  that 
  of 
  

   cotarnine, 
  however, 
  we 
  shall 
  see 
  that 
  if 
  we 
  add 
  to 
  the 
  latter 
  two 
  equivalents 
  of 
  

   oxygen, 
  and 
  subtract 
  from 
  it 
  the 
  formula 
  of 
  apophyllic 
  acid, 
  the 
  difference 
  is

  I 
  have, 
  however, 
  been 
  unable 
  to 
  determine 
  whether 
  this 
  group 
  of 
  atoms 
  passes 
  

   into 
  any 
  particular 
  form 
  of 
  combination, 
  or 
  whether 
  it 
  be 
  entirely 
  oxidised 
  into 
  

   carbonic 
  acid 
  and 
  water, 
  which 
  I 
  suspect 
  it 
  is. 
  

  

  Apophyllic 
  acid 
  differs 
  from 
  anthranilic 
  acid 
  by 
  the 
  elements 
  of 
  two 
  equiva- 
  

   lents 
  of 
  carbonic 
  acid.

  According 
  to 
  Wohlee, 
  when 
  apophyllic 
  acid 
  is 
  distilled, 
  it 
  gives 
  a 
  quantity 
  of 
  

   chinoline. 
  From 
  our 
  knowledge 
  of 
  its 
  constitution, 
  however, 
  we 
  should 
  rather 
  

   anticipate 
  the 
  production 
  of 
  aniline, 
  or, 
  at 
  least, 
  of 
  an 
  isomeric 
  of 
  it, 
  particularly 
  

   if 
  distilled 
  with 
  excess 
  of 
  lime 
  or 
  baryta,

  By 
  distillation 
  I 
  obtained 
  a 
  small 
  quantity 
  of 
  an 
  oily 
  base 
  with 
  a 
  somewhat 
  

   aromatic 
  odour 
  ; 
  but 
  it 
  did 
  not 
  give 
  the 
  reaction 
  of 
  aniline 
  with 
  chloride 
  of 
  lime,
