every  three  or  four  hours,  according  to  the  action  or  the  effect 
desired.  Some  practitioners  neglect  the  use  of  this  agent,  be- 
cause it  does  not  act  so  powerfully  as  podophyllin,  and  hence 
lose  the  use  of  a  very  important  remedy  in  functional  derange- 
ment of  the  liver  and  other  organs  essential  to  digestion. 
METALLIC  WEALTH  OF  THE  UNITED  STATES. 
By  J.  D.  Whitney. 
In  a  work  on  this  subject,  recently  published  by  Messrs.  Lippin- 
cott,  Gratnbo  &  Co.,  of  this  city,  the  author  enters  into  a  careful 
investigation  of  the  mining  interests  of  the  United  States  in  com- 
parison with  those  of  other  countries.  The  following  extract, 
summing  up  the  production  of  metals,  is  taken  from  a  notice  of  the 
work  in  Silliman's  Journal  for  September,  viz  : 
A  general  summary  at  the  close  of  the  volume  is  given,  accom- 
panied by  a  tabular  statement  of  the  estimated  amount  and  value 
of  metals  produced  throughout  the  world  in  1854.  The  metals  se- 
lected are  gold,  silver,  mercury,  tin  copper,  zinc,  lead  and  iron.  The 
aggregate  of  these  are  as  follows  : 
Gold.  Silver.  Mercury.  Tin.  Copper.  Zinc.  Lead.  Iron, 
lbs.  troy.  lbs.  troy.  lbs.  av.  tons.  tons.  tons.  tons.  tons. 
481,950   2,965,200   4,200,000  13,660   66,900   60,550    133,000  5,817,000 
The  product  of  the  United  States  in  gold  is  set  down  at  200,000 
pounds,  Australia  and  Oceanica  at  150,000,  and  Russia  at  60,000 
Mexico  and  South  America  47,100.    Of  silver,  the  New  World 
supplies  2,473,700  pounds,  leaving  only  the  small  residue  of 
491,500  lbs.  for  all  other  countries.    Of  mercury,  Spain  gives  the 
world  2,500,000  lbs.,  and  the  United  States  100,000  lbs.  England 
and  Australia  furnish  over  half  of  all  the  copper  produced  by  the 
world  :  the  present  product  of  the  United  States  being  in  this  metal 
only  3,500  tons.    Prussia  and  Belgium  furnish  four-fifths  of  all 
the  zinc  used  in  the  world  (viz.  16,000+33,600  tons.)    Lead  is 
distributed  between  Great  Britain,  Spain  and  the  United  States  in 
the  ratio  of  4,  2,  1  (viz.  61,000,  30,000  and  15,000  tons  each.) 
England  furnishes  more  than  half  the  iron  of  the  world,  3,000,000 
tons,  and  the  United  States  1,000,000  tons.    France  is  the  next 
most  productive  country  in  iron,  600,000  tons.    Russia  produces 
but  200,000  tons,  and  Sweden  150,000  tons,  quantities  bearing  a 
very  small  relation  to  the  celebrity  of  product  of  those  countries.
