Inorganic  Chemical  Preparations.  By  Frank  Hall  Thorp,  Ph.D., 
Instructor  in  Industrial  Chemistry  in  the  Massachusetts  Institute  of  Tech- 
nology.   Boston  :  Ginn  &  Co.,  publishers. 
We  have  several  excellent  small  manuals  in  the  English  language  for  the 
manufacture  of  organic  preparations,  such  as  those  of  Cohen  and  Fischer,  but 
this  is  the  first  one  covering  the  ground  .of  inorganic  chemistry  in  the  same 
way.  It  has,  moreover,  several  new  and  distinctive  features  which  we  think 
are  of  value.  After  stating  the  formula  and  molecular  weight  of  each  com- 
pound, it  gives  the  materials  and  quantities  of  the  same  needed  for  the  prepa- 
ration, and  full  working  directions  for  the  carrying  out  of  the  manufacture, 
followed  by  the  reactions  involved  and  the  properties  of  the  product.  Under 
the  latter  head,  the  author  gives,  in  a  large  number  of  cases,  tables  showing 
the  solubility  of  the  salt  in  water  at  different  temperatures,  and  the  specific 
gravity  of  solutions  of  different  strengths.  For  these  tables  the  authorities  are 
invariably  given.  While  the  book  wants  a  table  of  contents,  the  substances 
are  alphabetically  arranged  and  an  index  follows. 
A  valuable  introductory  chapter  on  solution,  precipitation,  filtration,  decan- 
tatiou,  washing,  evaporation  and  crystallization,  abounding  in  valuable  sug- 
gestions, has  not  been  overlooked.  S.  P.  S. 
The  Principles  of  Theoretical  Chemistry,  with  special  reference  to 
the  constitution  of  chemical  compounds.  By  Ira  Remsen,  Professor  of 
Chemistry  in  the  Johns  Hopkins  University.  Fifth  Edition.  Lea  Brothers  & 
Co.,  Philadelphia  and  New  York.  1897. 
It  has  been  the  aim  of  the  author,  in  the  latest  edition  of  this  valuable  work, 
to  bring  it  in  accord  with  all  the  recent  advances  of  chemical  science.  The 
salient  features  of  this  book  are,  that  it  contains  a  clear  statement  of  theoretical 
chemistry  in  a  moderate  space.  It  is  therefore  not  so  formidable  to  the 
beginner  as  several  of  the  larger  works  on  this  subject,  yet  it  contains  abun- 
dant information  to  equip  the  student  for  almost  any  amount  of  research  work.
