The  quantity  of  ash  yielded  by  the  seed  of  Moldavian  and 
Chevalier  barley  and  of  their  produce  on  clay  is  singularly  alike,, 
the  numbers  being  almost  identical  ; but  the  similarity  vanishes 
when  the  produce  on  sand  is  examined.

In  examining  the  table  which  exhibits  the  composition  of  Che- 
valier barley  we  perceive  considerable  differences  in  the  propor- 
tion of  the  principal  ingredients  ; more  especially  is  this  the  case 
with  phosphoric  acid,  of  which  there  is  one-third  more  in  No.  3 
than  in  No.  1.  The  same  remark  applies,  although  in  a less 
degree,  to  the  analyses  of  Moldavian  barley.
