I commenced an examination of the turnip, its top or leaves and root, but it remains 

 unfinished from want of time. The leaves contain in 500 parts 85-92 of dry matter and 

 415-08 water, or 17-18 per centum of dry matter; ash 13-69, or 2-73 per centum of in- 

 organic matter. Of this 13 -69, 3-69 is silica, 2-35 earthy phosphates, 1-25 carbonate of 

 lime, -615 magnesia, 1-26 potash, and 3-73 soda. The composition was influenced by 

 an unmanured soil, and by a small quantity of adherent foreign matter.
