has  been  considerably  extended,  and  many  chemical  formulae  introduced 
that  have  been  needed  in  laboratory  calculations. 
It  would  be  useless  in  a  limited  space  to  enter  into  even  an  enumeration 
of  the  additions  that  have  been  made  in  this  edition,  nor  has'our'time  been 
sufficient  to  compare  it  with  the  preceding  ;  yet  from  a  general  glance  over 
we  observe  the  same  attention  to  accuracy  in  details  which  have  heretofore 
so  eminently  characterized  the  work.  It  has  been  the  aim  of  the  authors 
to  make  the  Dispensatory  as  comprehensive  as  possible  ;  much  it  contains 
in  close  foot-notes,  and  many  valuable  results  are  condensed  in  short  para- 
graphs of  the  text;  where  several  have  written  on  the  same  subject,  ab- 
stracts of  each  are  given  where  each  possesses  merit.  This  will  be  noticed 
at  the  articles  "  Tinctura  Ferri  Chloridi,"  Strychnia,  Cinchona,  etc.  So 
much  has  been  discovered  in  relation  to  the  ethers  that  Dr.  Bache  found 
it  necessary  to  almost  wholly  reconstruct  that  abstruse  chapter,  and  the 
same  may  be  said  of  that  on  Glycerin.  We  hope  to  be  able  hereafter  to 
point  out  more  in  detail  the  new  features  of  the  Dispensatory,  but  must 
conclude  the  present  notice  with  the  opinion,  that  it  in  all  respects  keeps  up 
its  well  earned  character,  as  a  guide  book  in  materia  medica  and  pharmacy 
to  the  physician  and  apothecary,  as  well  to  the  practitioner  in  his  office 
or  shop,  as  to  the  student. 
As'^regards  the  mechanical  execution,  the  printer  has  done  well ;  but  in 
regard  to  paper  the  publisher  might  have  done  better ;  yet  the  anxiety 
to  compress  the  size  of  the  volume  may  excuse  the  deficiency  in  this 
respect. 
Elements  of  Inorganic  Chemistry  ;  including  the  applications  of  the  Science 
in  the  Arts.  By  Thomas  Graham,  F.  R.  S..  L.  &  E.,  &c.  Edited  by 
Henry  Watts,  B.  A.,  F,  C.  S.,  and  by  Robert  Bridges,  M.  D.  Second 
American,  from  the  second  revised  and  enlarged  London  edition.  Com- 
plete in  one  volume,  with  233  illustrations  on  wood.  Philada.  Blan- 
chard  &  Lea,  1858  :    pp.  852. 
In  1852,  the  first  part  of  this  work,  including  the  non-metallic  bodies, 
and  the  alkaline  and  earthy  metals,  amounting  to  over  430  pages,  was  pub- 
lished in  this  city  under  the  revision  of  Prof.  Bridges,  from  the  London 
edition.  Owing  to  circumstances,  the  principal  of  which  has  been,  no 
doubt,  the  engagements  of  the  author  in  the  Royal  Mint,  he  has  not  found 
time  to  go  on  with  the  work,  and  it  remained  in  the  condition  it  was  left 
by  the  author  in  1852,  until  recently,  when  Wm.  Henry  Watts,  F.  C.  S., 
well  known  as  the  translator  of  Gmelin's  Hand-book  for  the  Cavendish 
Society,  engaged  to  edit  the  remainder  of  the  work,  under  the  superinten- 
dence of  the  author,  and  has  written  an  extensive  supplement  of  200  pages, 
which  applies  chiefly  to  the  first  part  previously  published,  thus  bringing 
that  very  important  portion  up  to  the  present  condition  of  science.  In 
the  last  part  of  the  text  just  brought  out  an  important  feature  is  "  the
