poses  precludes  the  manufacture.  But  from  the  strong  salines 
our  supply  is  derived  in  large  quantities.  At  Tarentum,  Sligo, 
and  Natrona  in  Western  Pennsylvania,  Pomeroy,  Ohio,  and 
Kanawha,  West  Virginia,  the  manufacture  of  bromine  has 
becom.e  of  considerable  importance.  The  production  of  1870 
will  reach  125,000  lbs.,  a  quantity  probably  in  excess  of 'our 
consumption.  In  1867  the  Stassfurt  product  of  bromine  was 
nearly  20,000  lbs. 
The  total  product  of  iodine  in  Great  Britain  and  France  is 
about  200,000  lbs.  annually,  and  outside  these  two  countries 
very  little  is  produced.  As  the  average  product  of  iodine  is 
about  10  lbs.  to  the  ton  of  kelp,  and  it  requires  20  tons  of  wet 
weed  to  produce  one  ton  of  kelp,  this  total  product  represents 
the  burning  of  400,000  tons  of  sea-weed.  At  the  present  price, 
the  iodine  produced  is  of  more  value  than  the  alkaline  salts, 
which  were  the  original  object  of  the  industry. 
As  previously  stated,  iodine  is  not  produced  in  the  United 
States.  Since  its  use  was  first  established  here  the  price  has 
fallen  from  $16.00  to  about  $5.00  per  lb.  At  present,  bromine 
is  furnished  for  less  than  $1.50  per  lb. 
The  chief  consumption  of  bromine  and  iodine  is  for  medicinal 
purposes  in  the  form  of  iodides  and  bromides  of  potash,  soda,  or 
ammonium.  A  small  proportion  is  consumed  in  photography. 
Bromine  has  been  proposed  as  a  discharge  in  calico  printing, 
and  during  the  late  war  was  to  some  extent  employed  as  a  disin- 
fectant. As  yet,  but  a  small  proportion  of  the  bromine  of  the 
saline  mother-liquors  is  economized  ;  but  should  the  manufactu- 
rers turn  their  attention  to  this  important  substance,  the  conse- 
quent reduction  in  price  will  render  its  economical  employment 
in  other  directions  possible. — Amer.  Chemist,  Aug.,  1870.

Sulphur  is  a  substance  v/hich  has,  if  not  a  fragrant,  at  least  a' 
decided  odor,  and  is  useful,  both  internally  and  externally.  Be- 
sides these  purely  personal  uses,  it  is  largely  used  in  this  country 
in  the  manufacture  of  sulphuric  acid,  and  for  other  manufactur- 
ing purposes.    As  a  matter  of  course  the  source  of  supply  be-
