In  regard  to  sodium  phosphate  solution,  Prof.  I.  V.  Stanley 
Stanislaus  said,  that  the  United  States  Pharmacopoeia  directs  in  the 
compound  solution  of  sodium  phosphate  the  employment  of  un- 
effloresced  crystals  of  the  salt.  The  manufacturers  supply  the  salt 
in  barrels,  boxes  or  paper  cartons,  whereby  the  sodium  phosphate 
loses  about  25  per  cent,  of  its  water  of  crystallization,  becoming  so 
strengthened  in  the  normal  salt  content,  that  upon  the  solution  of 
such  an  effloresced  salt,  the  excess  of  the  normal  dried  salt  crystal- 
lizes out. 
Now,  whereas  the  crystallized  official  sodium  phosphate  contains 
603  grammes  of  water  of  crystallization  in  each  kilo,  the  difference 
between  this  and  603  (1000  —  603  =  397)  or  397  grammes  of  the 
exsiccated  sodium  phosphate  U.S. P.  should  be  employed  to  make 
1000  c.c.  of  the  compound  solution,  the  quantities  of  sodium  nitrate, 
and  citric  acid  and  water  remaining  the  same. 
The  solution  prepared  as  just  stated  will  not  deposit  crystals  of 
sodium  phosphate,  and  if  hot  water  is  employed  it  can  .be  made 
with  the  greatest  saving  of  time,  and  is  of  the  U.  S.  P.  strength. 
President  Howard  B.  French  presented  to  the  college  specimens 
of . the  following  coniferous  Japanese  plants:  Golden  Shinoro,  20 
years  old ;  pot,  Shigaragi  ware.  Avalagi,  25  years  old ;  pot,  Shiga- 
ragi  ware.  A  Japanese  table  garden,  worked  by  Mr.  Harada.  An 
excellent  specimen  of  Xanthoriza  was  presented  by  Prof.  Charles 
H.  LaWall.  A  vote  of  thanks  was  tendered  the  donors  of  these 
specimens. 
JANUARY. 
The  fourth  of  the  present  series  of  pharmaceutical  meetings 
was  held  on  Tuesday  afternoon,  January  19,  at  3  o'clock,  with 
Dr.  C.  A.  Weideman,  Recording  Secretary  of  the  college,  in  the 
chair. 
Prof.  Charles  H.  LaWall  read  a  paper  on  "  The  Differentiation  of 
the  Enzymes  in  Milk  by  the  Use  of  Hydrogen  Peroxide  and  Its 
Tests."  (See  this  Journal,  p.  57.)  The  paper  was  discussed 
by  Dr.  Lowe,  Mr.  England,  Professor  Kjaemer  and  the  author. 
Prof.  LaWall  called  attention  to  the  fact  that  in  the  employment  of 
Hehner's  test  in  detecting  formaldehyde  in  milk,  negative  results 
were  not  indicative  that  formaldehyde  was  not  present.    The  test
