In  commenting  upon  the  use  of  the  microscope  in  the  examina- 
tion of  substances  in  small  quantities,  Professor  Kraemer  said  that 
as  a  result  of  experiments  which  he  had  carried  out  there  were 
certain  difficulties  in  the  work  which  prevented  the  uniform  crystal- 
lizing of  the  same  substance.  He  had  found  that  on  crystallizing 
solutions  of  alum  in  watch  crystals  the  crystals  separate  in  three 
or  four  different  forms  apparently  of  the  same  system,  although  he 
thought  that  even  the  system  of  crystallization  might  be  different 
but  had  not  investigated  this  point  as  yet.  It  is  well  known  that 
calcium  oxalate  occurs  in  the  monoclinic  and  tetragonal  system. 
In  other  words,  microscopic  physical  conditions  must  be  taken  into 
account  in  work  of  this  kind.
