these  in  comparison  to  the  platinum  gramme  divisions,  and  I  am  sur- 
prised that  they  are  not  more  generally  adopted  in  our  laboratories. 
The  set  contains  14  weights,  from  J  a  gramme  to  J  a  miligramme. 
As  to  brass  or  copper  divisions,  I  have  always  considered  them  inac- 
curate, for  they  tarnish  very  rapidly  in  an  atmosphere  which,  for  that 
of  a  laboratory,  might  be  considered  tolerably  pure.  Weights  of 
maillechort  (a  kind  of  German  silver)  resist  much  better  than  copper 
or  brass  weights  ;  I  have  a  set  since  the  year  1856,  the  gramme  divis- 
ions of  which  extend  only  to  the  centigramme,  and  are  perfectly 
bright  and  accurate  at  the  present  day,  but  they  have  only  been  used 
occasionally.

MALT  EXTRACTS. 
By  Albert  E.  Ebert. 
[The  author  states  that  two  classes  of  preparations  are  known  under 
this  title,  one  analogous  to  lager  beer  having  a  three  per  cent,  alcohol 
strength,  of  which  the  preparations  of  Hoff  and  Koch  are  examples; 
whilst  the  other  kind  is  saccharine  and  gummy  in  their  nature,  and 
usually  bear  the  name  of  Liebig.  The  author  considers  the  first  class 
to  be  good  beer  at  an  exhorbitant  price,  and  criticises  severely  those 
professional  men  who  have  given  it  their  endorsement. 
The  second  class  of  Malt  Extracts,  of  which  Ed.  Loeflund  and  Dr. 
H.  E.  Linck,  both  of  Stuttgard,  are  makers,  are  put  up  in  patent 
medicine  style,  and  though  claimed  as  original,  this  point  is  question- 
able, as  Malt  Extract  has  long  been  known  in  Great  Britain  and  Bel- 
gium as  well  as  in  Germany.] 
Prof.  Liebig  does  not  lay  any  claim  to  the  discovery  or  introduction 
of  this  preparation  ;  we  have  heard  him,  during  his  lectures,  denounce 
this  attachment  of  his  name  to  these  extracts,  it  having  been  done  in 
opposition  to  his  wishes  by  parties  who  hoped  to  increase  their  sales 
by  this  seeming  endorsement  of  their  articles.  We  have  lately  made 
the  malt  extract,  at  the  urgent  request  of  physicians,  and  give  here- 
with the  process,  so  that  pharmacists  may  prepare  it  themselves,  in- 
stead of  relying  upon  the  specialist  to  supply  it  at  exorbitant  prices.
