_The Cabbage._--The composition of the Drumhead Cabbage has been studied by Dr. Anderson. He found a larger proportion of nutriment in the outer leaves than in the "heart," and ascertained that the young plants were richer in nutriment than those more advanced in age. His results show the desirability of cultivating the open-leaved, rather than the compact varieties of this plant. ANALYSIS OF THE CABBAGE.--BY DR. ANDERSON. Outer leaves. Heart leaves. Water 91·08 94·48 Compounds containing nitrogen 1·63 0·94 Compounds destitute of nitrogen, such as gum, sugar, fibre, &c. 5·06 4·08 Ash (mineral matter) 2·23 0·50 ------ ------ 100·00 100·00 According to Fromberg, the composition of the whole plant is as follows:-- Water 93·40 Nitrogenous, or flesh-forming compounds 1·75 Non-nitrogenous substances such as gum, sugar, &c. 4·05 Mineral matter 0·80 ------ 100·00 Dr. Voelcker, who has more recently analysed the cattle cabbage, furnishes us with the following details of its composition:-- COMPOSITION OF CABBAGE LEAVES (OUTSIDE GREEN LEAVES). Water 83·72 Dry matter 16·28 ------ 100·00 The fresh and the dry matter consisted of:-- Fresh Dry matter. Matter. Per cent. [*] Protein compounds 1·65 10·19 Non-nitrogenous matter 13·38 82·10 Mineral matter 1·25 7·71 ----- ------ 16·28 100·00 [* Containing nitrogen ·26 1·63] In the following table the results of a more elaborate analysis of the _heart_ and inner leaves are shown:-- COMPOSITION OF HEART AND INNER LEAVES.
