This  specimen  is  kept  in  the  top  gallery,  where  the  temperature  is  fre- 
quently high. 
There  is  nothing  remarkable  about  the  camphor  oil,  it  is  similar  in 
appearance  to  laurel  camphor  oil  which  has  lately  been  introduced  here. 
Its  specific  gravity  is  0'882.  Mr.  Jamie  says  of  it,  "Every  camphor  tree 
yields  a  large  quantity  of  oil  which  is  very  much  used  externally  for 
rheumatism  by  all  classes,  and  is  often  used  as  an  adulterant  of  cajeput 
oil,  being  considerably  cheaper  than  it.  The  camphor  oil  might  be  used 
instead  of  the  PharmacoiDoeia  lin.  camphor?e,  I  have  seen  it  frequently 
prescribed  in  place  of  it. 
I  beg  to  express  my  indebtedness  and  thanks  to  Mr.  Jamie  for  his  valu- 
able information.  -Fhar.  Jour,  and  Tt-ans.,  March  28,  1885,  pp.  795-796. 
Note.— In  a  note  to  '  Phar.  Jour,  and  Trans.,"  May  2,  1885,  Mr.  J.  R.  Jackson  states 
that  two  samples  of  Baros  camphor  in  the  Kew  Museum  corresponding  to  the  third 
quality,  as  classified  by  Mr.  MacEwan,  have  deposited  crystals;  one  of  these  samples 
was  sent  from  Borneo  by  the  late  Mr.  Motley  in  1851,  the  other  from  Sumatra  by  Dr.  de 
Vriesse  in  1855.  The  superior  kinds,  whiter  and  larger  crystals,  received  at  the  same 
time,  sliow  no  deposit  whatever.  The  specimens  are  not  subjected  to  any  very  high 
temperature. 
A  sample  of  Baros  camphor  corresponding  to  the  first  quality  described  above  has 
been  in  our  possession  for  about  twenty  years,  and  was  presented  to  us  by  the  late  Prof. 
Procter,  wlio,  we  believe,  received  it  from  the  late  Daniel  Hanbury.  The  bottle  is  kept 
in  closet,  where  during  the  summer  the  temperature  may  reach  occasionally  95  or 
100°  F. ;  during  the  fii  st  ten  or  twelve  years  no  sublimate  was  observed,  but  since  that 
a  moderate  amount  of  crystals  lias  formed  in  the  upper  part  ol'  the  bottle.— Editor

A  Treatise  on  Practical  Chemistry  and  Qualitative  Inorganic  Analysis, 
adapted  for  use  in  the  laboratories  of  colleges  and  schools.  By  Frank 
Clowes,  D.  Sc.,  Lond.,  etc.  With  illustrations.  From  the  fourth  Eng- 
lish edition.    Philadelphia  :  Lea  Brothers  &  Co.,  1885.    12mo,  pp.  376. 
We  may  simply  repeat  the  favorable  opinion  which  we  expressed  after 
the  examination  of  a  previous  edition  of  this  work  (see  ''Am.  Jour.  Phar.," 
1881,  p.  143).  It  is  practical  in  its  aims  and  accurate  and  concise  in  its 
statements.  Slight  changes  in  the  arrangement  were  very  judiciously 
made.  Thus  the  first  section  now  treats  of  the  preparation  and  use  of  ap- 
paratus, which  are  necessary  in  performing  the  experiments  with  certain 
gases  and  liquids,  described  in  section  II ;  the  use  of  the  spectroscope  has 
been  tranferred  from  the  appendix  to  the  analytical  operations  in  section 
III,  etc.  Among  the  new  matter  added  in  the  present  edition,  may  be 
mentioned  in  section  VI  the  reactions  of  various  organic  matters,  such  as 
alcohol,  starch,  glucose,  urea,  albumen,  six  of  the  most  important  alkaloids, 
and  nine  organic  acids  ;  the  latter,  we  think,  would  be  more  conveniently 
considered  with  tartaric  and  other  organic  acids  in  section  IV,  and  the 
number  might  be  increased  by  cinnamic  and  malic  acids,  which  are  fre- 
quently met  with. 
But  these  transpositions  and  additions  do  not  represent  the  only  or  main 
changes  in  the  present  edition  ;  of  far  greater  importance  is  the  care  which
