text: The morphogenetic effects of lithium ions and embryonic animalizers have been described by Schweikhardt (1966): increased cell length, apical size, and stripe width, and delayed primordial development, are seen in lithium chloride; decreased size, broad base, narrow stripes, and complete failure of primordial formation in, for example, sodium thiocyanate, iodosobenzoic acid, or zinc salts.
