A  Monument  to  Liebig. — The  following  circular  has  been  issued  at  Berlin : 
Committee  for  Erection  of  a  Liebig  Memorial. 
Bureau,  No.  10  Dorothea  St.,  Berlin. 
Berlin,  April  29,  1873. 
Honored  Sir, — In  its  session  of  April  28th,  the  directors  of  the  German 
Chemical  Society  unanimously  decided  to  honor  the  memory  of  Justus  Yon 
Liebig  by  the  erection  of  a  statue  either  in  Darmstadt,  Giessen,  or  Munich. 
A  committee,  consisting  of  the  undersigned,  was  empowered  to  take  the 
necessary  steps  to  carry  out  this  decision. 
In  making  known  to  you  this  decision  of  the  directors  of  the  German  Chem- 
ical Society,  we  hasten  to  inquire  of  you  whether  you  are  disposed  to  become 
a  member  of  the  general  committee  for  the  erection  of  a  Liebig  Memorial. 
In  case  of  an  affirmative  answer,  which  we  earnestly  request,  we  will  have 
the  honor  to  send  to  you,  in  a  few  days,  the  call  to  be  signed. 
The  Committee. — A.  W.  Hoffmann,  C.  A.  Martius,C.  Scheibler. 
This  call  has  since  been  issued  and  a  large  committee  appointed,  ihe  mem- 
bers residing  in  different  countries. 
Australian  Soluble  Gums. — The  number  of  arborescent  species  of  Acacia 
furnishing  gum  is  not  inconsiderable.  The  species  indigenous  to  Australia  are 
of  greater  celerity  of  growth  than  the  African  gum  Acacias.  Gum  a  good  deal 
resembling  Arabic  is  obtained  from  Acacia  harpophylla,  Ferd.  Mueller;  A. 
Bidwillii,  Bentham  ;  A.  pycnantha,  Bentham  ;  A-  decurrens,  Willdenow ;  and 
A.  homalophylla,  Cuming.  It  has  been  exported  for  cotton  printing,  adhesive 
purposes,  and  other  applications.  The  supply  can  be  rendered  abundant. —

Indian  Opium. — The  poppy  being  exclusively  grown  for  the  Supreme  Gov- 
ernment of  India  in  Benares  and  Behar,  the  permission  of  the  Lieutenant- 
Governor  of  Bengal  has  been  sought  and  obtained  on  the  subject  of  improving 
its  cultivation.  The  opium  manufactured  in  the  Himalayas  contains  50  per 
cent,  more  morphia  than  that  of  the  plains  of  India.  This  fact  was  placed  on 
record  in  the  "Journal  of  the  Agri-Horticultural  Society  of  India." — Pharm. 
Journ.  (Lond.),  July  12,  1873. 
Manna,  etc.,  from  Palermo. — From  the  consular  reports  we  find  that  the 
shipments  of  manna  from  Palermo  were  1345  cwt.,  valued  at  £8189,  in  1870, 
and  2530  cwt.,  valued  at  £14,642,  in  1871.  Most  of  this  gees  to  France.  The 
trade  in  essences  and  essential  oils  also  shows  a  large  increase,  having  risen 
from  8890  lbs.,  valued  at  £1252,  in  1870,  to  49,800  lbs.,  valued  at  £6620,  in 
1871.  There  are  five  manufactories  of  concentrated  lemon  juice  and  essences 
in  that  city,  which  turn  out  400  pipes  annually. — Ibid.
