Again, the animal cell is constantly producing carbonic acid and nitrogenous waste, but these are the first necessities of life to our alga, which removes them, so performing an intracellular renal function, and of course reaping an abundant reward, as its rapid rate of multiplication shows.
Weismann, who has most fully elaborated a hypothetical scheme of the relations of the intracellular units, identifies the larger of these units not with the ordinary granules of the cell, but with a remarkable structure called chromatin, which becomes aggregated within the cell nucleus at the time of cellular division a structure which divides into definite parts and goes through some most suggestive manoeuvres in the process of cell multiplication.
It is a micro-organism which penetrates the tissue, and selects and impregnates it, sets it vibrating, gives it /another life./ But the exciting agent of this intracellular activity, instead of being the normal germ of life, is a parasite." He went on to describe the process minutely and in highly scientific terms, and ended up by saying: "The cancerous tissue never achieves full development.
For our present knowledge of the power of intracellular digestion possessed by the endoderm cells of the lower invertebrates removes all difficulties both as to the mode of entrance of the algae, and its fate when dead. In short, we have here the relation of the animal and the vegetable world reduced to the simplest and closest conceivable form.
