34 THE ENZYME TREATMENT OF CANCER
precise bio-chemical methods can now be applied to the study of the growth of cancer, and brings new and exact information as to the nature of the relations existing between The tumour and the animal bearing it. The effect which a growing tumour produces upon a normal organism is a problem of nutrition similar to the growth of a foetus in a pregnant animal ; it cannot be explained by assuming the formation of pathogenic ‘ cancer ferments or ‘cancer toxins.’ “ In the foregoing the italics are mine, and they are introduced to draw attention to the method of citing the “ new and exact information.”
As demonstrating the exact opposite of this information, one may cite the following recent words of Blumenthal and Neuberg: “ Moreover, we consider the question of the abnormal enzymatic (ferment) processes in tumours as completely cleared up, since it has also been answered in a positive sense by Abderhalden and his colleagues, working with quite other methods.” The original German of this passage will be found in a short article by Blumenthal and Neuberg’on” Proteolytische Fermente der Krebszelle,” in Zeitschr. f. Krebsforschung, vol. x., pp. 246-247, 1911. For further evidences and for the present position of the matter, Blumenthal and Neuberg refer to Neuberg, “ Handbuch der Biochemie,” “ Chemie der Neuhildungen,” 1909 ; also to the same author, in Zeitschr. f. Krebsforschung, vol. x., 1910; and to Blumenthal, “ Ergebnisse der Physiologic,” “ Die chemische Vorgänge bei der Krebskrankeit, ” pp. 363-428, 19I0 separate edition of the memoir (Asher-Spiro, Berlin), 1910.
In a review of Bainbridge’s report, the Lancet (October 9, 1909, p. 1079) states “ A negative result of this kind has the great value we have indicated, in that the medical profession have before them chapter and verse
