Rapports  sur  les  Expositions  internationales  de  Peche  de  Boulogn' -sur-mer, 
Arcachon  et  du  Havre  (1866 — 1868).  Par  le  docteur  J.  L.  Soubeiran,  secre-

Report  on  the  international  expositions  of  fishery  at  Boulogne,  Arcachon  and 
Havre.    8vo,  187  pages. 
The  first  international  fishery  exposition  was  held  at  Amstardam  in  1861, 
when  most  of  the  maritime  nations  of  Europe  displayed,  besides  the  products, 
the  various  apparatus  and  appliances  which  are  used  by  them  to  secure  the 
numerous  products  of  the  sea.  Towards  the  close  of  the  same  year  the  city  of 
Boulogne  decided  upon  a  similar  exposition  in  this  important  French  port.  The 
project  was  ready  for  execution  in  1865,  by  which  time,  however,  the  comple- 
tion of  the  new  museum  at  Bergen,  Norway,  offered  an  opportunity  to  hold  the 
second  international  fishery  exposition  there,  and  necessitated  the  postponement 
of  the  one  contemplated  at  Boulogne  to  the  following  year,  when,  simultane- 
ously, a  similar  exposition  took  place  at  Arcachon,  which  bore  more  of  scientific 
character,  and  was  mainly  ichthyological  At  the  universal  exposition  of  Paris* 
held  in  1867,  a  certain  space  was  also  accorded  to  the  products  of  the  sea  and 
rivers,  and  in  1868  the  city  of  Havre  arranged  an  international  maritime 
exposition,  in  which  large  quantities  of  commercial  products  of  importation  and 
exportation  found  a  place  beside  the  special  maritime  products  and  apparatus. 
The  author,  who  had  previously  reported  to  the  Societe  d'acclimatation  upon 
the  two  expositions  held  outside  of  France,  now  reports  upon  those  held  in  that 
country,  as  far  as  they  related  to  the  subjects  mentioned  before.  The  report, 
which  was  first  published  in  the  "Bulletin  de  la  societe  d'acclimatation,"  2 
serie,  t.  viii,  1871,  now  appears  in  book  form,  and  contains,  in  a  compact  form, 
much  valuable  information  of  the  various  fishes  which  are  of  commercial  im- 
portance, and  of  the  pisciculture  now  successfully  carried  on  in  many  countries. 
The  work,  though  not  designed  to  be  exhaustive  of  the  subject,  is  a  valuable 
addition  to  the  literature  on  these  subjects.

"  The  Lens"  perished  in  the  great  Chicago  fire  before  the  first  number  was 
mailed  ;  the  number  before  us  is  not  an  exact  reproduction  of  that  ill-fated  one. 
While  it  will  be  mainly  conducted  in  the  interests  of  microscopy,  valuable  con- 
tributions on  any  branch  of  natural  science  will  not  be  excluded.  A  good  be- 
ginning is  made  in  this  first  number  by  an  enumeration  of  the  flora  of  Chicago 
and  vicinity,  by  H.  H.  Babcock.  The  other  papers,  nearly  all  original,  relate 
to  various  subjects  connected  with  microscopy.  To  judge  from  this  first  num- 
ber, we  expect  "The  Lens"  will  fill  a  vacant  space  creditably,  and  we  wish  it 
that  success  which  it  aims  to  deserve  by  its  original  and  selected  matter,  as  well 
as  by  its  well  executed  wood-cuts  and  engravings.
