study  of  special  subjects  or  branches.  More  than  eighty  experiments  are 
described,  illustrating  the  methods  used  in  preparing  the  principal  classes 
of  compounds,  and  the  fundamental  reactions  involved  in  their  transforma- 
tions, tlius  showing  the  way  to  the  proper  study  of  this  important  branch 
of  science. 
The  book  deserves  to  be  widely  known  among  students  of  pharmacy, 
medicine  and  others  whose  aim  is  not  merely  a  knowledge  of  a  few  isolated 
facts,  but  a  sound  foundation  upon  which  correct  knowledge  of  causes  and 
effects  jnay  be  based.  The  book  is  well  printed  ;  the  proof-sheets  have  been 
carefully  read  ;  the  equations  explaining  the  reactions  are  numerous  ;  gra- 
phic formulas  are  judiciously  used  to  a  limited  extent ;  a  limited  number 
of  illustrations  showing  the  arrangement  of  apparatus  in  the  performance 
of  certain  experiments  have  been  added;  and  nothing  of  importance 
appears  to  have  been  omitted  for  accomplishing  the  objects  had  in  view.
