neoua  faith  and  obscure  art  in  their  numerous  ramnifications,  and  is  there- 
fore a  most  valuable  contribution  to  the  history  of  the  gradual  progress  of 
culture,  and  likewise  of  literature  since  the  voluminous  writings  of  the  al- 
chemists and  of  the  rosicrucians  are  concisely  cited  and  explained. 
Written  in  the  full  light  of  the  present  knowledge  of  chemical  laws  and 
proven  facts,  its  language  is  nevertheless  so  free  from  technicalities,  and  its 
diction  is  so  engaging  and  captivating,  that  it  will  be  read  with  undimin- 
ished interest,  not  only  by  chemists,  but  by  cultivated  people  generally.  It 
sounds  almost  like  fiction  that  in  this  enlightened  age  the  art  of  gold  mak- 
ing still  lingers  in  some  secluded  localities,  and  that  the  faith  in  its  success 
nickers  occasionally  in  the  brain  of  some  honest  student. 
Aus  der  Molecular-Welt.  Eine  Gratulations-Schrift  an  Eobert  Bunsen,

From  the  world  of  molecules. 
An  excellent  little  work  treating  in  a  humorous  manner  of  the  modern 
views  of  atoms,  molecules  and  chemical  compounds.  The  author  states  in 
the  preface  that  it  was  first  written  in  1876,  but  laid  aside,  until  a  few  years 
ago,  he  concluded  to  revise  it  for  publication  in  commemoration  of  the 
seventy-first  anniversary  of  the  birth  of  his  friend  Prof.  Bunsen,  who  at  that 
time  was  sojourning  in  Naples.  The  book  must  be  read  to  appreciate  its 
attractive  humor  and  also  its  fine  points  of  sarcasm. 
Memoire  sur  les  Volumes  Moleculaires  des  Liquids.     Par  Hermann  Kopp. 
Heidelberg:  C.  Winter,  1886,  8vo.  Pp.  47. 
Memoir  on  the  molecular  volumes  of  liquids. 
This  memoir  was  written  in  reply  to  one  by  Bartoli,  which  appeared  in 
Annates  de  Chimie  et  de  Physique,  March,  1886,  and  which  condemned  in 
principle  the  results  of  a  long  series  of  researches,  published  by  Professor 
Kopp  more  than  thirty  years  ago  in  Liebig's  Annalen.  The  rejoinder,  in 
which  the  author  undertakes  to  point  out  various  errors  of  Mr.  Bartoli,  in- 
validating his  conclusions,  was  intended  for  publication  in  the  same  journal 
in  which  the  latter's  paper  appeared;  but  owing  to  a  rule  governing  publica- 
tions in  the  Annates,  to  avoid  controversies  likely  to  assume  a  personal 
character,  it  was  suggested,  but  not  concurred  in  by  the  author,  to  suppress 
certain  sentences  from  Mr.  Kopp's  memoir,  which  he  considered  essential,  or 
with  the  view  of  an  early  publication,  to  materially  abridge  it.  The  cor- 
respondence given  in  the  preface,  refers  to  this,  as  well  as  to  some  matters 
connected  with  the  history  of  alchemy  published  by  Mr.  Berthelot.  The 
subject  matter  of  the  memoir  itself  treats  of  questions  the  elucidation  of 
which  has  formed  a  considerable  portion  of  the  author's  prolonged  scien- 
tific labors.
