— except '  organized  labor.'  They  denounce  bitterly  any  union  on  the 
part  of  those  who  buy  their  cotton  to  raise  the  price  of  products 
manufactured  from  it,  but  they  earnestly  advocate  the  adoption  of 
measures  to  make  the  manufacturers  pay  higher  prices  for  the  staple. 
The  president  of  the  Cotton  Growers'  Association  has  issued  an 
address  calling  conventions  of  the  Texas  farmers  at  Waco,  Texas, 
March  8th ;  of  those  in  the  Mississippi  Valley  at  Memphis,  March 
ioth,and  of  those  east  of  the  Mississippi  at  Augusta,  March  15th,  to 
secure  '  concert  of  action,'  as  '  by  a  systematic  and  judicious  market- 
ing of  our  crops  we  can  realize  inestimable  benefits  that  never  can  be 
secured  permanently  otherwise.'  The  method  urged  upon  the  cot- 
ton growers  is  that  which  is  so  bitterly  complained  of  when  applied 
to  the  cotton  manufacturers — a  restriction  of  the  output  in  order  to 
secure  higher  prices.  '  Destroy  the  annual  surplus  of  cotton  '  is  the 
watchword.  '  You  will  be  better  off  with  a  7,000,000-bale  crop  sell- 
ing at  10  cents,  supplemented  by  ample  food  crops,  than  with  a 
10,000,000-bale  crop  selling  at  5  cents.'  " 
"  AN  EXAMINATION  OF  SOME  OFFICIAL  LEAD 
PREPARATIONS. 
By  Frederick  w.  Haussmann. 
Sub-Committee  of  Research  of  the  United  States  Pharmacopceial  Committee 
of  Revision. 
The  observation  that  certain  official  preparations  prepared  from 
lead  salts  differed  from  the  standard  prescribed  by  the  Pharma- 
copoeia, induced  the  writer  to  inquire  into  the  cause  of  such 
variations. 
Continued  investigations  revealed  the  fact  that  the  statements  of 
the  Pharmacopoeia,  regarding  the  preparations  under  examination, 
were  also  open  to  criticism,  and  in  the  course  of  this  paper,  altera- 
tions and  additions  which  may  be  regarded  necessary  will  be 
mentioned. 
The  experience  of  other  pharmacists  is  invited  to  be  rendered 
for  comparison  either  to  corroborate  or  disprove  the  conclusions 
arrived  at  by  the  writer. 
The  original  researches  were  confined  to  Goulard's  extract,  the 
liquor  plumbi  subacetatis  of  the  Pharmacopoeia,  where  the  first 
deviations  from  the  official  standard  were  noticed.  It  was  soon 
found,  however,  that,  to  determine  the  exact  causes  thereof,  it  was 
also  necessary  to  examine  the  metallic  ingredients,  lead  acetate  and 
oxide.
