This experiment was carried out to elucidate the changes of the distribution of nitrogenous components in skin during the storage of green salted skin. Influences of three kinds of treatments, which were, fleshing before curing, soaking in 10% NaCl solution with 20 p. p. m. chlorotetracycline before curing and repeated salting after 3 days and 1 month of the first curing, on distribution of nitrogenous components in skin were compared.The results of this experiment indicated that the amounts of non-protein nitrogen and soluble protein nitrogen in these skin were less than in skin cured without any treatment, but no change was found about other nitrogenous components. Remarkably decreased amounts of non-protein nitrogen were found in the skin soaked in 10% NaCl solution with 20 p. p. m. chlorotetracycline before curing. Remarkably decreased amounts of soluble protein nitrogen were found in the skin cured thrice. When the skin of inferior freshness was cured, the amounts of non-protein nitrogen increased. But in the skin soaked in 10% NaCl solution with 20 p. p. m. chlorotetracycline before curing, these increased degree of non-protein nitrogen was lowered.
