    192                                  THE ENZYME TREATMENT OF CANCER

 

In certain independent laboratory estimations of these preparations, made by a fully competent chemist and physician in February, 1907, the tryptic power per ampoule of these preparations was found to be 9.6 Roberts tryptic units. That is to say, if preparations of such a strength of trypsin (9.6 units), and of the very slight amylolytic power of 0.37 amylolytic units, were now used for what Captain Lambelle and I regard as full normal doses, given daily or every other day, the following would be the procedure: The full daily dose of 1,000 tryptic units would require the use of quite 100 ampoules of 9.6 units, and the full dose of amylopsin could be obtained from more than 5,000 ampoules of the strength of 0.37 unit, or more than five litres. I com­mend these figures to certain transparently anonymous scribes, cancer researchers and ex-researchers, in the English medical press.

It has been pointed out that little or no evidences of the value of pancreatic ferments in malignant disease have been published in France or Germany. With our present knowledge of the requirements of the treatment, it would be surprising to find any positive evidence in the medical publications of either country. This lack of evidences is easily explicable. From Germany the total number of applications for general directions or for preparations to date (June, 1911) is two, all told, and doubtless most of the cases there treated received the German preparations mentioned by Dr. P. T. Hald (Lancet, November i6, 1907. pp. 1371-1375), and to his article the reader may be referred for information as to their strength (vide Appendix M).

The writer has not a single record of a request for injections as strong as 250 or 500 tryptic units from any French physician. Some French and Italian cases were
