Chemistry.  By  Brande  &  Taylor.  Second  American  edition,  thoroughly 
revised.  Philadelphia:  Henry  C.  Lea.  1867,  pp.  764,  octavo. 
The  work  of  Brande  &  Taylor  has  been  so  favorably  received  since  its 
introduction  to  the  American  public,  in  1864,  that  a  new  edition  was  re- 
quired, and  it  is  well  worth  mentioning  that  this  second  American  edi- 
tion has  been  very  carefully  revised,  and  enlarged  by  nearly  seventy  pages, 
by  Dr.  Taylor,  the  surviving  author,  Prof.  Brande  having  deceased  since 
the  first  edition  was  issued.  The  author  appears  to  have  extended  his 
care  to  all  portions  of  the  work,  organic  and  inorganic.  Among  the  for- 
mer, additions  will  be  found  at  chloroform,  nitro-glycerin,  anilin  colors, 
valerianates  of  soda  and  of  zinc,  petroleum,  &c.  Chemical  attraction,  saline 
solubilities,  spectrum  analysis,  and  other  subjects,  have  also  been  enlarged, 
so  that  the  claims  of  the  book  presented  to  the  student  are  strong  and  de- 
cided, as  being  up  to  the  present  time,  and  meriting  his  confidence.  The 
book  is  well  printed,  and  appears  to  have  been  duly  cared  for  in  passing 
the  press.

Three  numbers  of  this  excellent  monthly  have  reached  us — those  for 
April,  May  and  September — and  our  omission  to  notice  their  reception  has 
been  accidental  rather  than  intentional.  The  first  number,  containing  the 
prospectus,  we  have  not  seen  ;  but,  by  an  advertisement  appended  to  the 
September  number,  we  are  informed  that  the  publishers  are  much  encour- 
aged by  the  patronage  already  extended  to  the  work.  From  a  glance  over 
the  pages  we  are  satisfied  that  it  will  prove  a  valuable  means  of  creating  a 
taste  for  natural  history,  by  presenting  the  subject  in  a  form  attractive  and 
easily  understood.  Besides,  the  illustrations  and  typography  are  so  excel- 
lent that  the  work  is  an  ornament  to  the  table.  Our  farmers  should  en- 
courage it,  if  for  no  other  reason  than  to  get  information  of  a  reliable  char- 
acter about  the  insects  and  other  pests  that  are  attacking  their  crops,  grow- 
ing and  gathered.  It  is  not  often  that  so  much  true  science  is  served  in  a 
form  so  agreeable  and  attractive,  and  the  price  is  only  three  dollars  a  year. 
The  editors  have  our  best  wishes  for  continued  and  increased  success.

This  new  weekly  journal  commenced  its  career  with  much  promise.  Its 
articles  have  been  well  written,  its  contributions  excellent,  and  its  getting 
up  admirable,  being  one  of  the  best  printed  journals  received.  In  view  of 
all  this  it  is  with  regret  that  we  learn  from  the  Editor  that  the  publication
