1) Spectra in the ultraviolet and visible regions have
been obtained on samples of malononitrile under different
conditions. The samples were manufactured by several
companies in America and Sweden.
2) The spectral analysis has demonstrated that the
compound used by Hydén and Hartelius is not the same
as that employed by American investigators. If, however,
an aqueous solution of the American product is allowed
to stand at room temperature for a long enough time,
it develops the same spectral characteristics as the Swedish solution.
3) Future studies will concern themselves with attempts to identify, the active substance and to examine
its effect on neuronal nucleoproteins.
