CRUCIAL TEST OF THE NATURE OF CANCER 239
scientific investigation, published, unlike many other things, with the scientific experiments and evidences—if after this any man deny the truth of what is about to be affirmed on the word of a scientific investigator of nearly twenty-nine years’ standing, then it will be the time for the writer to make for himself the crucial test ; and this shall be done, and the results published, as soon as the necessary material has been obtained.
In Pasteur’s lectures* one may read:
“How can one avoid, for example, the assumption that corresponding to a dextro-rotatory body there must be a laevo-rotatory body, now that we know the cause of the dextro- and laevo-rotatory character? That would be to doubt that an irregular tetrahedron had an enantiomorphous image, or that for a right-handed screw there could be a corresponding left-handed screw, or that a right hand was matched by a left hand. Therefore the elementary constituents of all living matter will assume one or the other of the opposite asymmetries, according as the mysterious life-force which causes asymmetry in natural bodies acts in one direction or the other. Perhaps this will disclose a new world to us. Who can foresee the organization that living matter would assume, if cellulose were laevo-rotatory instead of being dextro-rotatory, or if the laevo-rotatory albumins of the blood were to be replaced by dextro-rotatory bodies? These are mysteries which call for an immense amount of work in the future, and to-day (1860) bespeak consideration in science.”
(1) It is, of course, a truism to state that the normal or somatic albumins are laevo-rotatory. (2) In the pancreas gland they form for themselves the wonderful
