This  is  an  excellent  work,  well  adapted  for  the  beginner  and  the  advanced 
student  of  chemistry.  The  numerous  facts,  the  established  laws  and  the  various- 
theories  are  given  and  explained  so  comprehensively  and  with  such  accuracyr 
as  to  show  at  once  not  only  the  able  chemist,  but  likewise  the  experienced 
teacher.  Tn  the  beginning  of  the  work,  the  use  of  technical  terms  is  almost  al- 
together avoided,  while  considerable  prominence  is  given  to  illustrative  experi- 
ments, all  of  which  are  well  described,  well  explained,  and  usually  illustrated 
with  appropriate  wood  cuts.  Many  of  the  processes  of  applied  chemistry  are  de- 
scribed, and,  with  their  apparatus,  illustrated.  With  the  adoption  of  the  atomic 
system  of  notation  (0=16,  &c.)  now  employed  by  the  large  majority  of  chemists, 
the  author  is  not  disposed  to  adopt  the  binary  theory  of  the  constitution  of  salts  j 
hence  the  old  nomenclature  for  the  salts  has  been  retained,  together  with  the 
formulas,  modified,  of  course,  by  the  change  in  the  atomic  weights  ;  but  the  bi- 
nary formulas  are  frequently  placed  alongside  of  the  former;  thus  we  find  for  bi- 
carbonate of  soda  Na2  0.  C02-  H2O.  CO2  or  NaHC(>3-  [Organic  chemistry  is  treated 
upon  nearly  200  pages  ;  the  space  allotted  to  it,  therefore,  does  not  permit  to  enter 
as  largely  into  details  as  in  the  first  part;  but  all  the  classes  of  organic  compounds 
have  been  duly  considered,  and  those  of  some  importance  in  the  arts  or  otherwise 
more  extensively  described. 
Not  the  least  commendable  feature  of  the  work  is  the  good  and  useful  index,  which, 
contains  not  only  the  names  of  all  the  elements  and  compounds  mentioned,  but  also 
their  symbols,  and  the  formulas  of  many,  so  that  bicarbonate  of  soda,  for  instance,, 
is  met  with  not  only  under  the  letter  S,  but  likewise  under  N,  as  NaHC03: 
A  careful  examination  of  this  work  has  convinced  us  that  it  is  one  of  the  best  for 
the  student  of  chemistry  in  its  general  relations,  and  in  its  applications  to  metal- 
lurgy and  other  extensive  industrial  manufactures. 
An  Introduction  to  Practical  Chemistry;  including  Analysis.  By  John  E.  Bowman,. 
F.C.S.,  &c.  Edited  by  C.  L.  Bloxam,  F.C.S.,  &c.  Sixth  American  from  the  sixth 
and  revised  English  edition.  Philadelphia:  H.C.Lea.  1873.  12mo.  pp.  339.

The  number  of  editions  through  which  this  little  work  has  passed,  is  sufficient 
evidence  of  its  value  to  the  chemical  student;  by  its  present  editor  it  has  been  tho- 
roughly revised  and  enlarged  by  many  additions.  It  appears  to  be  particularly 
adapted  for  the  advancement  of  those  students  who  may  be  compelled  to  experiment 
with  little  assistance  from  an  instructor.

This  being  the  twenty-third  year  of  the  publication  of  this  list,  its  convenient  ar- 
rangement and  its  usefulness  are  too  well  known  and  appreciated  to  require  any 
further  comment.

and  its  vicinity.
