by  Presenilis — precipitating  as  the  oxalate  and  weighing  as  the 
oxide. 
A  number  of  samples  examined  showed  : 
Calcium  oxide:  216  to  22-5  per  cent. 
Chlorides  and  sulphates  :  Traces — small  amounts. 
Solubility  tests :  About  as  given  in  preceding  parts  of  paper. 
Reaction  :  Slightly  acid — to  somewhat  alkaline. 
Physical  appearance  :  From  bulky,  white  powder  to  small  pearly 
white  crystals. 
The  above  examination  is  not  exhaustive,  but  is  rapid,  approx- 
imately accurate,  and  enables  the  pharmacist  to  arrive  quickly 
at  comparative  valuations  between  different  samples  of  calcium 
glycerophosphates.

RESEARCH  IN  MANUFACTURING  PHARMACY. 
By  Henry  Kraemer. 
The  original  investigator  has  always  been  assured  honor  and  a 
more  than  passing  record  of  his  work,  the  permanence  depend- 
ing upon  the  true  significance  or  value  of  his  achievements.  At  the 
present  time  the  research  worker  has,  in  addition,  a  chance  to  win 
some  of  the  largest  prizes.  Not  only  are  specific  sums  available  as 
in  the  Nobel  prizes,  but  other  funds  are  at  the  command  of  investi- 
gators, as  those  set  aside  by  the  Carnegie  Institution.  Moreover, 
there  are  opportunities  on  every  hand,  in  universities  as  well  as  in 
manufacturing  laboratories,  for  the  right  men  to  conduct  research 
and  make  great  discoveries. 
Many  remarkable  discoveries  have  been  made  by  those  connected 
with  universities.  In  recent  years  very  many  of  these  discoveries 
are  due  to  the  impetus  as  well  as  financial  assistance  and  facilities  of 
the  laboratories  of  large  manufacturing  houses.  The  many  alkaloids 
of  cinchona,  opium,  etc.,  or  the  constituents  of  many  of  the  volatile 
oils  would  probably  never  have  become  known  were  it  not  that 
tons  of  material  have  been  worked  up  in  large  manufacturing  labo- 
ratories and  the  material  placed  at  the  command  of  research 
workers. 
Not  only  is  this  true,  but  we  are  also  much  indebted  to  some  of 
these  manufacturing  firms  for  very  valuable  information  which  they
