14 THE ENZYME TREATMENT OF CANCER
Krukenberg. Thus it came about that, while the line of first advance was purely embryological, later a junction could be effected with the science of stereo-chemistry, and a further base for operations obtained in the fundamental discoveries of Pasteur on the asymmetry of naturally occurring organic compounds.
The following remarks* (literally translated), by Professor F. Blumenthal, of Berlin, concerning “ trypsin” and cancer are of interest: “ For a long time the trypsin-therapy of Beard awakened greater hope. This depends upon the quick digestion of the cancerous tumour by trypsin. If trypsin or pancreatin be injected into a cancer, one notes a fairly quick softening of the same, leading to a liquefaction, which is aseptic, not made up of pus. In some cases it appears that in small and readily accessible tumours it has been possible with the help of trypsin to cause the tumour to disappear. I will recall only the case in the aural clinic of Munich. In larger tumours, especially with metastases, I have only had failures. Successes also seem to he lacking in mouse tumours, as Bashford reported.** In the treatment with

** It would appear not to have occurred to Professor Blumenthal that this statement might have reference to inert ferments. Since the experiments, which must be supposed to have led to this erroneous conclusion, have never yet been published, and since they are, indeed, not mentioned in a single word in the Third Scientific Report of the Imperial Cancer Research Fund, published in 1908. and, lastly, since there are no scientific or other evidences extant to show that ferments of any kind or sort had ever been employed in these unpublished experiments, I feel bound to ask Professor Blumenthal to explain, as a scientific man, why he cites these unpublished experiments and nonexistent evidences ? It is common enough to note in scientific publications that published experiments or evidences have been ignored by the author, but it is something quite new to find unpublished experiments and mythical evidences cited in a
