These results, as well as those of others, we have fully discussed 

 elsewhere {Phil. Trans., 1859, aud Jour. Chem. Soc, vol. xvi, 1863), and 

 we can only very briefly refer to them in this place. 



The column of actual gain or loss shows in one case, with colza, 

 a gain of more than 1 gram nitrogen ; and the amount in the products 

 is more than forty-one times as much as that supplied as combined
