Fourth  Report  on  the  Analysis 
variety  is  not  so  well  known  or  so  widely  cultivated  as  the  com- 
mon red  kinds,  we  have  thought  it  necessary  to  examine  the 
latter.  The  carrots  were  obtained  from  Mr.  Paine,  of  Farnham, 
being  the  growth  of  1847,  of  the  sort  called  “ Long  Red  Surrey,” 
on  poor  but  deep  sand.

There  is  a sensible  difference  between  the  mineral  composition 
of  the  Belgian  carrots  before  analyzed  and  the  present  specimens 
of  the  common  variety.  But  whether  this  difference  is  to  be 
traced  to  the  variety  of  the  plant,  or  to  any  peculiarity  in  the  soil, 
manure,  or  season,  we  have  not  the  means  of  judging. 
Cow-Cabbage. 
The  following  is  an  ash  analysis  of  a large  variety  of  cattle 
cabbage,  called  the  “Flatpole”  or  “Drumhead,”  for  which 
we  are  indebted  to  the  kindness  of  Mr.  Fowler,  of  Dartmoor. 
The  crop  was  grown  upon  newly-reclaimed  land,  well  manured 
with  cattle-dung.  It  was  considered  worth  while  to  make  a 
separate  analysis  of  the  head  of  the  cabbage  and  the  lower  por- 
tion of  the  stalk.
