{Botanical Laboratory, The University, Ann Arbor, Michigan.)
Scahlek and Szegvary, and Svedberg, have recently
described remarkable instances of sudden liquefaction of
inorganic colloidal gels which have a striking analogy in the
collapse of the gel structure of the protoplasm of a dividing
echinoderm egg when the latter is subjected to mechanical
pressure. It is the purpose of this paper to call attention to
this analogy.
