A  portion  of  this  was  then  evaporated  to  a  crystallizing  point, 
set  aside,  and  produced  the  sal  Rochelle. 
The  mother  liquor  from  the  above,  with  the  other  portion  of 
the  liquor,  was  then  used  for  obtaining  the  cream  of  tartar  and 
tartaric  acid. 
To  a  portion  of  it  hydrochloric  acid  was  added,  which  caused  a 
precipitate  of  bitartrate  of  potash,  as  a  crystalline  powder.  This 
was  drained  on  a  filter,  and  then  washed  with  distilled  water  and 
dried. 
The  tartaric  acid  was  made  by  precipitating  tartrate  of  lime, 
by  solution  of  chloride  of  calcium,  from  the  other  portion  of  the 
original  liquor  (solution  of  sal  Rochelle),  the  resulting  tartrate 
of  lime  washed,  and  then  decomposed  by  sulphuric  acid,  the  Sul- 
phate of  lime  separated  by  filtration,  and  the  solution  of  tartaric 
acid  evaporated  to  a  certain  point,  so  as  to  deposit  any  dissolved 
tartrate  of  lime,  then  filtered,  and  again  evaporated  and  crystal- 
lized.

By  E.  S.  Wayne. 
The  specimen  of  quicksilver  ore  was  handed  to  me  for  exami- 
nation by  J.  S.  Bonham,  of  Concord,  Tenn.  The  locality  in 
which  it  is  found  is  in  Macon  county,  Tenn.,  near  the  dividing 
ridge  that  separates  the  waters  flowing  into  the  Atlantic  arid 
Gulf  of  Mexico,  and  forty  miles  from  Wall  Hollow,  S.  C,  and 
thirty  miles  from  the  line  of  railroad  from  Cincinnati  to  South 
Carolina.  The  specimen  is  a  talcose  rock,  containing  quicksilver 
in  the  metallic  state.  From  the  description  given  to  me,  there 
is  an  immense  vein  of  the  material.  By  analysis  I  found  that  it 
yielded  7 J  per  cent,  quicksilver  (150  pounds  to  the  ton).  From 
the  appearance  of  the  specimen  when  handed  to  me,  and  the 
statement  made  by  the  party  that  it  contained  quicksilver,  I 
thought  that  it  was  merely  a  conjecture  upon  his  part,  but  analy- 
sis proved  the  correctness  of  the  statement,  both  by  wet  and  dry 
assay.    A  portion  of  the  ore,  placed  in  a  glass  tube  and  heated,
