Am.  Tour.  Pharm. 
July,  1921. 
Following  the  six  chapters  mentioned  are  to  be  found:  Appen- 
dix I,  Key  to  Nomenclature  of  Chemical  Compounds ;  Appendix 
II,  Displacement  Series ;  Appendix  III,  The  Periodic  System  and 
Classification  of  the  Elements ;  Appendix  IV,  Solubility  Table  of 
Compounds;  Appendix  V,  Preparation  of  Salts  and  Key  to  Equa- 
tions, and,  finally,  a  very  useful  Index  and  Glossary. 
The  type  and  composition  of  the  book  are  satisfactory  and  the 
language  clear  and  concise,  but  the  volume  shows  numerous  evi- 
dences of  the  lack  of  the  careful  proof  reading  that  should  be  given 
all  text-books,  and  particularly  those  .in  which  much  of  the  text  is 
in  the  form  of  formulas  or  equations  in  which  every  letter,  figure 
and  other  character  counts  for  so  much. 
The  reviewer  unhesitatingly  recommends  the  book  to  any  per- 
son who  desires  a  clear,  compact  treatise  on  equation  writing.
