138 THE ENZYME TREATMENT OF CANCER
Of the ferments of the sexual generations, by far the most important is that first discovered by the Court physician, Baron Corvisart, and to which afterwards Professor W. Kuhne gave the name of “ trypsin.” It is this enormously powerful ferment, trypsin, upon which Nature relies for the suppression of trophoblast in normal mammalian gestation. Lower down in the scale than the mammals she associates with it its complement, amylopsin. Foetal blood of a mammal does not contain this latter, and the foetal pancreas gland does not produce it. In the human pancreas gland amylopsin is not formed until some few months after birth. The reason of this is not far to seek. When in the ancestral mammals uterine development was initiated, along with it and following its close there was evolved the mammary nutrition. In this amylopsin is not needed, and its production by the pancreas gland was postponed until the milk nutrition was done with. The mammary nutrition is (on the testimony of more than one embryologist: thus, on that of my friend J. P. Hill, as well as on my own) older in time than the allantoic placenta. The latter was introduced to defer the birth period, and by prolonging the gestation, as detailed in my “ Span of Gestation,” to bring the young into the world in a more perfect state. In prolonging the gestation, the mammary nutrition was postponed, and in this way the appearance of amylopsin upon the scene put off to an even later period. This has led to grave difficulties and dangers in human gestation, for there is no such thing in nature as a ferment possessing both proteolytic and amylolytic powers.*
The proper scientific treatment of cancer is the enzyme or pancreatic one. If trypsin alone be used, bad symp-
