REMARKS  ON  THE  PREPARATION  OF  LIQUOR  BISMUTH  I. 
By  Albert  E.  Ebert, 
This  subject  was  introduced  by  Mr.  C.  R.  C.  Tichborne,  (Lond. 
Pharm.  Journ.,  Jan.  1864,)  and  was  thorougly  investigated  some 
months  later  by  Mr.  N.  Gray  JBartlett,  who  communicated  the 
results  of  his  examination  to  this  Journal  (Jan.,  1865.)  Since 
the  appearance  of  the  latter  paper  an  article  was  published  by  Mr. 
Thos.  P.  Blunt,  (Lond.  Pharm.  Journ.,  May,  1865)  in  which  Mr. 
Bartlett's  process  was  declared  unsatisfactory,  though  at  the  same 
time  a  formula  was  submitted  which,  in  all  essential  points,  was  but 
a  reproduction  of  that  of  Mr.  Bartlett.  Subsequently,  a  rejoinder, 
by  Mr.  Tichborne,  appeared,  (Lond,  Pharm.  Journ.,  June,  1865) 
reiterating  his  former  statements,  which  had  been  disputed,  and 
suggesting  another  method  of  preparing  liquor  bismuthi.  This 
consisted  in  dissolving  crystallized  ter-nitrate  of  bismuth  in  water, 
adding  a  due  proportion  of  citric  acid,  and  neutrallizing  the  liquid 
with  ammonia.  These  papers,  instead  of  further  elucidating  the 
subject,  have  left  it  in  such  a  state  of  uncertainty,  that  many  may 
be  deterred  from  attempting  the  preparation  of  liquor  bismuthi. 
The  large  demand  which  has  followed  the  introduction  of  this 
solution,  and  the  evidences  of  favor  with  which  it  has  been  re- 
ceived, convince  me  that  it  is  of  too  much  value  to  be  allowed 
to  fall  into  discredit  through  fallacious  formulas  or  the  disputes 
of  inventors. 
After  a  series  of  carefully  conducted  experiments  with  the 
different  processes,  I  have  arrived  at  the  following  conclusions : 
First.  Teroxide  of  bismuth,  though  recently  precipitated.
