﻿372 
  DB, 
  Anderson's 
  researches 
  on 
  some 
  of 
  the 
  

  

  and 
  I 
  did 
  not 
  obtain 
  it 
  in 
  sufficiently 
  large 
  quantity 
  for 
  analysis. 
  Chinoline, 
  I 
  

   conceive, 
  it 
  cannot 
  possibly 
  be, 
  but 
  whether 
  it 
  is 
  aniline, 
  or 
  a 
  base 
  isomeric 
  with 
  

   it, 
  I 
  shall 
  for 
  the 
  present 
  leave 
  an 
  open 
  question. 
  My 
  impression 
  certainly 
  is, 
  

   that 
  it 
  is 
  not 
  aniline, 
  and 
  it 
  is 
  quite 
  conceivable 
  that 
  the 
  decomposition 
  may 
  be 
  

   very 
  different, 
  and 
  that 
  during 
  distillation 
  only 
  two 
  equivalents 
  of 
  carbonic 
  acid 
  

   are 
  separated, 
  as 
  is 
  the 
  case 
  in 
  every 
  other 
  instance 
  if 
  the 
  production 
  of 
  a 
  volatile 
  

   base 
  ; 
  and 
  in 
  that 
  case 
  we 
  should 
  have 
  a 
  substance 
  isomeric 
  with 
  anthranilic 
  acid, 
  

   and 
  possessing 
  basic 
  properties. 
  

  

  Apophyllate 
  of 
  Silver. 
  — 
  This 
  salt 
  can 
  only 
  be 
  obtained 
  by 
  digesting 
  apophyllic 
  

   acid 
  in 
  solution 
  upon 
  moist 
  carbonate 
  of 
  silver, 
  filtering 
  from 
  the 
  excess 
  of 
  car- 
  

   bonate, 
  and 
  precipitating 
  the 
  solution 
  with 
  a 
  mixture 
  of 
  alcohol 
  and 
  ether. 
  The 
  

   salt 
  is 
  thrown 
  down 
  as 
  a 
  perfectly 
  white 
  powder, 
  of 
  a 
  more 
  or 
  less 
  crystal- 
  

   line 
  appearance, 
  and 
  which 
  colours 
  slightly 
  by 
  exposure 
  to 
  the 
  light. 
  It 
  is 
  ex- 
  

   tremely 
  soluble 
  in 
  water, 
  sparingly 
  soluble 
  in 
  alcohol, 
  and 
  insoluble 
  in 
  ether. 
  It 
  

   does 
  not 
  explode 
  when 
  heated, 
  and 
  undergoes 
  a 
  slow 
  decomposition, 
  leaving 
  

   behind 
  metallic 
  silver. 
  As 
  precipitated 
  from 
  the 
  original 
  solution 
  it 
  is 
  liable 
  to 
  

   retain 
  excess 
  of 
  oxide 
  of 
  silver, 
  and 
  requires 
  to 
  be 
  purified 
  by 
  a 
  second 
  solution 
  

   in 
  water 
  and 
  reprecipitation 
  with 
  alcohol 
  and 
  ether.

  Apophyllate 
  and 
  Nitrate 
  of 
  Silver. 
  — 
  When 
  a 
  solution 
  of 
  nitrate 
  of 
  silver 
  is 
  

   added 
  to 
  one 
  of 
  an 
  alkaline 
  apophyllate, 
  a 
  rather 
  sparingly 
  soluble 
  crystalline 
  salt 
  

   is 
  deposited, 
  which 
  has 
  been 
  described 
  by 
  Wohler 
  as 
  the 
  apophyllate 
  of 
  silver. 
  It 
  

   is, 
  however, 
  a 
  double 
  compound 
  of 
  that 
  salt 
  with 
  nitrate 
  of 
  silver. 
  It 
  explodes 
  

   violently 
  when 
  heated, 
  and 
  the 
  silver 
  must 
  be 
  determined 
  as 
  chloride.
