CRUCIAL TEST OF THE NATURE OF CANCER 241
stance upon which it acts “as a key fits a lock.” Now, on a previous page, reference has been made to the “liquefaction of cancer” by means of potent hypodermic injections of trypsin. This has been seen more than once by a London consulting physician, who sent me several tubes of such liquid cancer from two patients suffering from epithelioma (skin-cancer). As already stated, the accuracy of this observation has been confirmed by Professor F. Blumenthal, of Berlin, and by the observations made by Captain Lambelle in the treatment of the two cases of lympho-sarcoma and sarcoma.* Since no observation refuting this has ever been published, it stands as a discovery doubly confirmed by observation. As hundreds of medical men have found, trypsin does not “ liquefy” the normal somatic laevo-rotatory albumins of the body and blood, although in some very advanced cancer cases, where they have been much injured by the action of the cancer, it may not be without some action upon them.** It follows from all this that, even without the use of the polarimeter, the scientific
* Bainbridge’s sixth thesis on p. 32 of his “ Scientific Report” reads:” That injectio trypsini, in some cases, seems to cause more rapid disintegration of (to ‘liquefy,’ according to Beard) cancerous tissue.” Since to this author it only “ seems “ to do this, and since his report does not contain a particle of evidence of the fact, I do not here cite—because there are none to quote—. any observations of his as confirming this undoubted fact. It suffices that Professor Blumenthal and Captain Lambelle have witnessed it, the latter in two cases. Possibly, Dr. Bainbridge never saw it at all, except in the microscopical preparation, or preparations, which I sent him in 1907.
** Such cases are probably much too advanced for success to be possible. A medical friend has recently written to me that in every disease there is a point beyond which the case is hopeless, and that blood-examinations in cancer cases under treatment were very desirable. In my opinion, this again indicates the folly of operation on living cancer, for this does but stimulate its growth and increase, until anon this point is reached. Then it is too late for any treatment to be successful.
