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.
