The proportion of leaf would appear rather larger than in the 

 turnips or mangold- wurzel ; but it is unsafe to judge from so 

 limited a series. 



The water in the roots is, if anything, less than in beet or 

 turnip, and most certainly so in the leaf — the leaf of carrots 

 should, therefore, be more valuable. 



The ash in the root is no way different in quantity from that of 

 either of the root crops just mentioned, but that of the leaf is seen 

 to be very much greater. This is important, and will be noticed 

 again almost immediately. The analyses of five specimens of the 

 root ash are before given and included in the following table : —
