solation  from  the  book,  and  spiritualists  will  find  but  little  more  comfort,  for 
both  are  treated  to  a  mild  vein  of  sarcasm  that  is  all  the  more  searching 
because  of  its  freedom  from  bitterness. 
The  author  has  ventured  to  discuss  many  things  which  few  writers  in  the 
past  have  dared  to  undertake.  We  are  told  that  "  matter  is  retarded  motion," 
and  this  is  demonstrated  by  the  most  acute  process  of  reasoning.  He  also  dares 
to  denounce  the  hypothetical  ether  which  scientists  have  invented  to  account 
for  the  transmission  of  heat,  light,  etc.,  and  declares  there  is  no  need  for  it. 
It  is  impossible,  in  a  review,  to  give  the  details  of  how  these  ends  are  attained, 
but  the  book  itself  must  be  studiously  read,  not  once,  but  twice  or  thrice.  The 
vivid  description  of  the  drunkard's  den,  and  the  masterly  portrayal  of  the  effects 
of  certain  narcotics  are  the  products  from  a  writer  of  extraordinary  resources. 
In  the  words  of  the  author,  we  may  say  "to  many  this  manuscript  will  prove 
a  passing  romance,  to  others  an  enigma,  to  others  still  it  will  be  a  pleasing 
study,"  and  we  might  add  that  those  who  get  anything  out  of  it  will  be  required 
to  study  it.  The  author  is  at  once  a  scientist  and  a  philosopher;  he  has  also 
shown  himself  to  be  a  master  of  a  peculiarly  beautiful  literary  style  which,  in 
some  chapters,  may  be  termed  word-painting  of  the  highest  order  ;  in  fact,  the 
book  is  full  of  figurative  gems  like  the  following  :  "As  all  the  bubbles  in  a  glass 
shrink  and  vanish  when  the  first  collapses,  so  the  troupe  of  fairy-like  forms  be- 
fore me  disintegrated  and  were  gone."  We  have  no  authority  for  making  the 
statement,  but,  in  our  opinion,  there  is  but  one  name  possible  in  connection 
with  the  authorship  of  this  mysterious  book,  and  that  is  John  Uri  Lloyd. 
A  Handbook  of  Industrial  Organic  Chemistry.  Adapted  for  the  use 
of  manufacturers,  chemists  and  all  interested  in  the  utilization  of  organic 
materials  in  the  industrial  arts.  By  Samuel  P.  Sadtler,  Ph.D.,  F.C.S.  Second

Something  over  three  years  ago  the  first  edition  of  this  work  was  reviewed  in 
this  Journal.  Since  that  time  the  author  has  collected  considerable  new 
material  and  amplified  that  already  written.  The  valuable  bibliography  has 
been  carefully  brought  to  date,  and  the  statistics,  wherever  obtainable,  have 
been  revised  to  the  present  year.  It  is  needless  to  say  that  these  two  features 
alone  greatly  add  to  the  value  of  the  volume. 
The  general  treatment  of  the  several  industries,  as  adopted  in  the  first  edition, 
has  been  continued,  viz.:  (1)  enumeration  and  description  of  the  raw  material; 
(2)  the  processes  of  manufacture;  (3)  the  products,  both  intermediate  and 
final;  (4)  the  most  important  analytical  tests  and  methods;  (5)  bibliography 
and  statistics.  When  an  industry  has  been  written  up  in  the  order  of  these 
headings,  the  subject  is  practically  exhausted, 
Among  the  numerous  additions,  we  note  one  which  will  be  appreciated  by 
pharmacists,  namely,  the  enlargement  of  the  chapter  on  soaps,  so  as  to  include 
those  manufactured  for  toilet  purposes. 
Considerable  new  material  has  been  added  to  the  chapter  on  oils;  the 
"  chrome  tanning  "  process  has  been  included  in  the  processes  of  manufac- 
turing leather,  and  the  chapters  on  the  textile  industries  have  been  consider- 
ably amplified.  The  appendix  has  been  enlarged  by  a  table  on  the  physical 
and  chemical  properties  of  the  fixed  oils  and  fats.    Some  two  years  ago,  the
