LIKE the publication by Dr. Bainbridge, the contribution* of Messrs. Ball and Thomas professes to be a “scientific report.” As already stated, unlike the former document, the publication of the latter does give information—such that a searching scientific investigation can be made into the details of the procedure adopted. It must be recalled that, in the words of this report, “Two cases of carcinoma were placed on trypsin treatment in May, 1906, in the Cancer Wards of the Middlesex Hospital, but with negative result, there being no improvement in the patients, nor was the progress of the growth influenced by the trypsin injections.” Here the authors omitted to notice two significant facts of these cases, one had a single injection, and the preparation used had at that time been found to be inert in ferment powers by others as well as by myself.

There is no mention of any employment of
