Abstract
The hematopoietic actions offour complex salts of cobalt were examined on rabbits. Purpureo salt did not bring about any significant altering in blood findings but other three salts, that is, Carbonatotetrammine cobaltic nitrate, Flavo salt and Croceo salt, produced polycythemias. Among these complex salts which revealed itself to be effective, there were noticed a certain differences in its effects quantitatively as well as qualitatively.
