Solutions  containing  T^Ww[  and  2  0  0\00,  of  vanillin 
were  then  prepared  and  all  were  found  to  give  positive  results  with 
the  resorcinol-sulphuric  acid  test,  although  the  90q00-q-  dilution  re- 
quired some  time  for  the  rose-colored  zone  to  appear  and  no  definite 
reaction  could  be  obtained  with  any  higher  dilution  than  this.  The 
phenol-sulphuric  acid  test  was  not  quite  so  delicate,  being  sensitive 
to  !  Q  (/q  q  0 ,  while  the  Hehner  test  was  found  to  be  sensitive  in  about 
this  degree  also.

The  first  or  opening  session  was  held  on  Tuesday  afternoon  in  the

of  expediting  the  work  of  the  convention  by  transacting  many  of 
the  routine  matters  in  advance  of  the  opening  session,  which  is  al-
