Chickens, nitrogenous ration, weighed 8 lb. 15 oz. Chickens, carbonaceous ration, weighed 9 lb. 1 oz. The four lots were placed in separate pens where they remained during the entire experiment, which lasted 125 days. They were fed and watered once daily, and an account kept of the food eaten and water drank.
It is now proved that every plant begins its existence under the same form; that is to say, in that of a cell a particle of nitrogenous matter having substantially the same conditions.
It will not help our girls much, for instance, to have learnt the number of cubic feet of oxygen that is necessary for turning the purple blood into scarlet the amount of nitrogenous, phosphatic, carbonaceous, and other elements which are requisite for building up new tissue, etc., etc., and many other dry facts of a kindred nature, if she does not put this knowledge to practical use.

And therefore this remarkable result came out that however much a plant may differ from an animal, yet that the essential constituent of the contents of these various cells or sacs of which the plant is made up, the nitrogenous protein matter, is the same in the animal as in the plant.
The protoplasm in the form of the primordial utricle is, as it were, the animal element in the plant, but which is imprisoned, and only becomes free in the animal; or, to strip off the metaphor which obscures simple thought, the energy of organic vitality which is manifested in movement is especially exhibited by a nitrogenous contractile substance, which in plants is limited and fettered by an inert membrane, in animals not so."
Much of the substance of the loaves and fishes with which He fed the multitude the carbon and nitrogenous products also came from the air, though He could have taken them from many other sources. The combination and building up of these in the ordinary way would have taken weeks or months, but was performed instantaneously by His mighty power."
While the oxidation of alcohol into acetic acid may take place by purely chemical means, these processes are not practical on a large scale, and vinegar manufacturers everywhere depend upon bacteria as their agents in producing the oxidation. These bacteria, several species in all, feed upon the nitrogenous matter in the fermenting mass and produce the desired change in the alcohol.
During the second period one of the chickens fed nitrogenous food, and during the third period another of the same lot were taken ill and removed from the experiment. Both seemed to be suffering from impacted crops, as the stomach and gizzard in each case were found to be empty.
*Urea* is the most abundant solid constituent of the urine and is the chief waste product arising from the oxidation of nitrogenous substances in the body. Although secreted by the cells lining the uriniferous tubules, it is not formed in the kidneys. The secreting cells simply separate it from the blood where it already exists.
