ing  and  most  important  meetings  that  this  Association  has  ever 
held.  The  attendance  is  expected  to  equal  if  not  exceed  that  of 
Boston  last  year,  and  extensive  preparations  are  being  made  to 
entertain  the  visiting  physicians  and  their  friends.  This  will  be  the 
third  meeting  in  Atlantic  City  within  a  decade,  evidencing  the  popu- 
larity of  this  known  resort  with  physicians. 
The  World's  Production  and  Consumption  of  Rubber,  for  the  year 
July  I,  1905,  to  June  30,  1906,  amounted  to  68,000  tons  and  62,574 
tons  respectively.  Of  the  68,000  tons  produced  in  this  period  over 
one-half  came  from  America,  about  23,400  tons  from  Africa  includ- 
ing the  East  African  Islands,  while  the  remaining  (1,800  tons)  came 
from  Asia  and  Polynesia.  Of  the  23,400  tons  of  African  rubber 
4,500  tons  were  produced  by  the  Congo  State,  1,500  tons  by  French 
Guinea,  1,250  tons  by  Angola  and  1,000  tons  by  the  Gold  Coast. 
In  America  Brazil  heads  the  list  with  a  production  of  41,000  tons. 
The  Central  American  States  furnished  400  tons,  Mexico  from  150 
to  200  tons  and  Bolivia  about  1,100  tons.  {B.  and  Col,  Drug.,  1907,

Hydrogen  Dioxide  as  an  Aid  m  the  Examination  of  Sputum. — Peters 
{Muench.  Med.  Woch.  Sckr.,  1907,  page  9)  recommends  the  addition 
of  hydrogen  dioxide  to  sputum  as  a  simple  and  most  effectual  means 
of  breaking  up  tenacious  masses  and  distributing  the  tubercle 
bacilli  evenly  through  the  specimen.  {Journal  American  Medical 
Association,  1907,  page  1556.) 
Use  of  Picrolonic  Acid  for  the  Alkaloidal  Valuation  of  Drugs  has 
been  reported  on  by  Matthes  and  Rammstedt,  who  have  conducted 
a  series  of  experiments  with  dinitro  phenyl  methyl  pyrazolone, 
known  as  picrolonic  acid,  for  the  quantitative  precipitation  of  certain 
alkaloids.  The  authors  have  demonstrated  the  working  accuracy  of 
this  method  with  mixtures  of  known  quantities  of  alkaloids  and 
have  devised  comparatively  simple  methods  for  determining  the 
alkaloidal  content  of  several  preparations  of  nux  vomica,  hydrastis 
and  jaborandi.    (^Pharmaceutical  Journal,  April  27,1907,  page  527-) 
Glucosides  of  Frangula  Bark. — Tunman  (Phar.  Cenfh,  1907,  page 
99)  reports  a  number  of  microchemical  and  gravimetric  analyses 
that  appear  to  indicate  that  the  amount  of  anthra  glucosides  con- 
tained  in  Frangula  bark  varies  at  different  times  of  the  year  and 
reaches  a  maximum  in  the  month  of  April.
