Improvement  of  Land  by  Warpiny. 
With  regard  to  the  processes  of  analysis  pursued  in  this  inves- 
tigation, all  that  need  be  said  is,  that  they  differed  only  in  a few 
minor  particulars  from  those  ordinarily  followed.  I must,  there- 
fore, beg  leave  to  refer  all  my  readers  who  may  wish  for  further 
information  to  Parnell’s  ‘ Elements  of  Chemical  Analysis,’  and 
Prof.  Johnson’s  4 Lectures  on  Agricultural  Chemistry  and  Geo- 
logy,’ in  which  works  they  will  find  everything  they  require. 
To  avoid  confusion,  it  will  be  observed,  that  I have  classified 
the  results  under  four  distinct  heads,  i.  e.,  A,  which  contains  those 
of  my  analyses  of  the  water  of  the  river  Trent,  taken  during  the 
warping  season ; B,  those  of  the  warp  from  various  localities  ; C, 
those  of  the  different  varieties  of  soil  ; and  lastly,  D,  which  in- 
cludes those  of  the  different  crops  grown  upon  natural  and  warped 
land. 
A.  Analysis  of  the  Warpiny  Waters. 
I. — The  first  specimen  examined  was  labelled  44  Water  taken 
from  the  warping  drain  before  going  on  the  land ; but  owing 
to  the  continued  rain,  there  was  much  fresh  water  in  the  River 
Trent,  and  the  warp  in  consequence  was  not  of  an  average 
quality.” 
Specific  gravity  of  the  filtered  water  at  58°  Fahren.  was  T00033.

* Those  substances  which  are  thus  marked  in  this  and  the  following  analysis  doubt- 
less existed  in  mechanical  suspension  in  the  water,  although  they  were  in  a state  of  too 
minute  division  to  be  stopped  by  a filter  of  white  bibulous  paper.
