Annotation by Joshua Lederberg:
KW: OCR n.g.;  This is part of Q71;
term paper for Gordon Whaley's course on Growth. I had become interested
in colchicine just around time I entered Columbia College as a freshman
in Sept. 1941; I may have started at the AISL that Spring.  It seemed
to me an important reagent for the physiology/toxicology of mitosis.
Cf also reviews on Colchicine; and experiments on effects of colchicine
on mouse spermatogenesis.  As far as I know the mechanism of the
gradient (permeability; export; inherent threshold of susceptibility)
has not been studied.  This item is related to Whaley letter to Lederberg,
