SUMMARY A satisfactory method of estimating biuret reactive material in semen is described. Human, ram, bull, fowl and dog semen vary in protein, proteose and peptide content. Values for biuret reactive material range from 1·80 gm./100 ml. in fowl semen to 7·32 gm./100 ml. in bull semen. Proteolysis occurred in human semen during incubation but was not detected in the semen of other species studied. Considerable species differences occurred in the amount of protein precipitated on heating semen at pH 4·6.
