From  1887  to  19 13  Russia  produced  7,837  poods  of  platinum 
and  exported  6,428  poods,  or  82  per  cent.  This  crude  platinum 
was  exported  to  France,  70.09  per  cent.;  Germany,  29.13  per  cent.; 
England,  0.78  per  cent.  About  400  to  450  poods  of  platinum  are 
used  annually,  and  half  of  this  amount  is  used  in  the  United  States. 
The  supply  of  platinum  in  explored  mines  is  estimated  at  7,000 
poods.  The  nuggets  found  in  the  Urals  were  sometimes  of  consid- 
erable weight:  In  1827,  io^/ig  funts;  1831,  20^/45  funts;  1832,

NOTE  ON  SINGLE  CHAMOMILES.^ 
By  K.  M.  Holmes,  F.L.S. 
Having  recently  had  samples  of  single  chamomiles  sent  to  me  for 
identification,  I  was  much  surprised  to  find  that  the  flowerheads 
were  not  those  of  Anthemis  nohilis,  but  of  Matricaria  chamomilla. 
As  there  is  no  double  variety  of  the  latter  in  commerce,  while 
there  are  sold  in  vScotland — or,  at  least,  in  Aberdeen —  the  true 
wild  single  flowers  of  Anthemis  nohilis,  this  is  all  the  more  curious. 
On  making  further  inquiries,  I  found  that  several  wholesale  houses 
in  London  were  in  the  habit  of  supplying  the  flowers  of  Matricaria 
chamomilla  when  single  chamomiles  were  ordered;   and  even  in
