[46] I have determined the amount of nitrogen contained in the meal made from the whole maize, the growth of the colony, as also from plantain meal; I have also ascertained its amount in cassava meal, prepared in the manner mentioned in the text, and in meal prepared from the cassava sliced, dried, and ground without expressing the juice. Assuming Liebig's formula of Proteine, namely, C-48 N-6 H-36 0-4 the results stand thus:—
| Nitrogen. Per cent. | Proteine compounds. Per cent. | |
| Maize meal (unhusked) | 1.73 | 10.72 |
| Plantain meal | .88 | 5.45 |
| Cassava meal (juice expressed) | .36 | 2.23 |
| Ditto from the sliced and dried roots | .78 | 4.83 |
