Adelaide,  South  Australia,  died  March  24,  aged  80  years.  He  was  a  younger 
brother  of  Sir  Robert  Hermann  Schomburgk,  who  died  26  years  before  him,  and 
for  some  years  had  accompanied  the  latter  in  his  travels  and  explorations. 
James  W.  White,  M.D.,  D.D.S.,  died  in  Philadelphia,  May  27,  in  the  sixty- 
fifth  year  of  his  age.  He  was  born  at  Hulmeville,  Bucks  Co.,  Pa.,  and  after 
the  death  of  his  father  was  raised  in  Burlington,  N.  J.  He  studied  medicine  at 
the  University  of  Pennsylvania.  At  the  time  of  his  death  he  was  the  senior 
member  of  the  firm  of  Hance  Brothers  &  White,  and  the  president  of  the  S.  S. 
White  Dental  Manufacturing  Company.  He  was  connected  with  the  Dental 
Cosmos,  as  contributor  and  editor,  since  its  establishment  in  1859.  He  was 
interested  in  a  number  of  philanthropic  undertakings,  and  in  1887  was 
appointed  president  of  the  Board  of  Charities  and  Correction,  an  unsalaried 
position  of  honor,  which  he  held  for  two  years,  when  he  was  removed  for 
refusing  to  acquiesce  in  what  he  conceived  to  be  a  violation  of  the  letter  and 
spirit  of  the  civil  service  laws  of  the  city.

Pepsin. —  The  Pharmaceutische  Centralhalle ,  June  4th,  1891,  describes  the 
production  of  pepsin  by  the  patented  method  of  J.  L,.  Webber,  which  consists 
in  macerating  animal  stomachs  with  acidulated  water,  clarifying  the  solution 
obtained  by  the  addition  of  sulphurous  acid,  removing  the  clear  liquid  from 
the  precipitate  and  then  separating  the  pepsin  from  the  peptone,  by  saturating 
at  a  higher  temperature  with  sodium  sulphate,  whereupon  pepsin  is  deposited 
whilst  the  peptone  remains  dissolved.  The  precipitate  is  dissolved  in  weak 
hydrochloric  acid ;  the  sodium  sulphate  is  removed  from  the  solution  by 
dialysis,  the  residual  liquid  concentrated  and  dried.  From  the  liquid,  out  of 
which  the  pepsin  is  deposited,  the  sodium  sulphate  is  separated  from  the  pep- 
tone by  recrystallization  on  cooling.  The  product  is  readily  soluble  and,  being 
free  from  peptone,  is  non-hygroscopic  and  permanent.  It  is  claimed  that  one 
grain  of  it  is  capable  of  dissolving  ten  thousand  grains  of  egg-albumen  accord- 
ing to  the  test  of  the  National  Formulary.
