Antineuritic yeast concentrates

Abstract

THIS work is being communicated now for two reasons. Confirmation of a previous statement is needed that preparations of activity under 0.1 mg. per day pigeon dose can be obtained from yeast. Moreover the details of pre- paring these more active concentrates are required in explanation of an ac- companying paper [Peters, Kinnersley, Orr-Ewing and Reader, 1928].
