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