producing  power,  then  this  was  equal  to  a  yearly  waste  of  187 
tons  of  meat  without  bone.  Estimating  the  meat  as  worth  six- 
pence per  pound,  this  amounted  to  a  loss  of  £10,472.  In  this 
way  the  waste  over  the  country  must,  he  said,  be  very  great. 
In  the  great  American  curing  establishments  the  brine  wasted 
must  be  something  enormous,  as  he  found  that  in  eight  of  the 
Federal  States,  4,000,000  pigs  were  slaughtered  and  cured  last 
season.  Mr.  Whitelaw  concluded  by  quoting  from  from  Greg- 
ory and  Liebig  as  to  the  value  and  efficacy  of  extract  of  meat. 
At  the  conclusion  several  gentlemen  expressed  their  approval 
of  the  p  iper,  and  the  desirability  of  such  a  practical  applica- 
tion of  dialysis  as  that  described  by  Mr.  Whitelaw. —  London

CINCHONA  NEWS. 
By  C.  W.  Quin,  F.  C.  S. 
In  the  Technologist  for  February  there  is  a  very  interesting 
paper  on  cinchona  culture  in  Jamaica,  by  Nathaniel  Wilson, 
the  island  botanist.  The  quinine-yielding  cinchonse  were  in- 
troduced into  the  island  in  the  autumn  of  1860  by  means  of 
seeds,  and  by  the  month  of  October  in  the  year  following  Mr. 
Wilson  had  the  satisfaction  of  possessing  over  four  hundred 
healthy  young  plants  ready  for  planting  out.  The  selection  of 
too  warm  a  site,  however,  killed  nearly  all  of  them,  and  it  was 
found  necessary  to  transplant  the  remainder  to  a  much  colder 
situation,  the  climate  and  soil  of  which  proved  to  be  all  that 
could  possibly  be  desired.  Some  of  the  plants  of  the  Cin- 
chona succirubra  have  attained  a  height  of  six  feet,  having  a 
circumference  at  the  base  of  the  stem  of  four  and  a  half  inches. 
The  grey  barks  O.  nitida  and  O.  micrantha  being  slower  in 
growth  have  not  reached  so  large  a  size.  So  far  the  experiment 
h'?s  proved  highly  successful,  and  Mr.  Wilson  states  that  it 
would  be  difficult  to  find  more  healthy  fruit  trees  in  the  neigh- 
borhood. It  is  calculated  that  in  about  four  or  five  years  the 
plants  will  yield  seeds;  in  the  mean  time  they  can  be  success- 
fully propagated  by  cuttings  and  layers.  It  seems  that  the 
climate  and  soil  of  the  higher  and  many  of  the  intermediate
