They [statements about macro-molecules in turn being bonded to other such molecules] undoubtedly have increased in number since our first-publication 10 years before. But also before that they were very numerous, and Frey-Wyssling's "points of adherence" [in macro-molecules] were quoted by biologists and chemists equally. In all this, one has again and again the impression as if in the immediate molecular and intermolecular range of magnitude one thinks of the presence of an adhesive or glue, which could be something different from --if functionally powerful -- simple direct chemical bonds. One should note that also the furniture maker's glue and rubber solution in the end work, it is true, unstoichiometrically, but still as "real" chemical facultative [= creating the possibility of] bonding.
