134 THE ENZYME TREATMENT OF CANCER
The line of primary germ-cells of the diagram (Fig. 5) is not made up of one only, destined to form an embryo, and of n - 1, destined for a future generation, but it is composed of a limited number, 2 or 4 or 8, often not so many, embryonic in destiny, of which as a rule one only becomes a normal embryo, and n - 2, or n - 4, etc., are set apart to provide for the cycle of unicellular organisms or germ-cells. Such a persistent embryonic germ-cell, encapsulated within the individual, may at any time, by illness, injury, irritation, or other cause—such as declining years—weakening the system, be awakened into activity. The “age incidence” of cancer is scientific nonsense, for it is only relative. Whenever this happens—the time is long past when it should have unfolded as an embryo, it attempts to resume the cycle, and its “unconscious memories only enable it to try to repeat the asexual portion of the cycle. Such an encapsulated germ-cell can only do one or other of two things in the end—and live. It may develop, and it only does this congenitally with the developing individual, or it may attempt to go on with the life-cycle. Skipping the formation of conjugating cells or gametes, it is brought to the next portion of the life-cycle—trophoblast.* In this way it becomes an irresponsible trophoblast, and it may imitate or mimic anything in its environment. Whatever it mimic—something existent or non—existent—it is always an ‘‘ imitation tissue,’’ and behind the domino or mask an irresponsible trophoblast.
In nearly all the foregoing, morphological aspects have been under consideration. It now behoves us to take account of the physiological and functional ones. The
