sometimes as low as 0.5, reaching a minimum before respiratory activity 
attains its maximum, which it does on the second or third day; (4) with 
healing, normal conditions again gradually prevail. 
NABOKICH: confirms” earlier results of Polowzoff* that a considerable 
part (25-50 per cent. of the CO, usually ascribed to the respiration of seeds 
in experiments is really due to the respiration of microorganisms, as shown 
by a comparison of the respiration of sterile and infected seeds. He also 
ascertained that the antiseptics used (bromin and corrosive sublimate) did 
not depress the respiration of the seeds, but clearly accelerated it.—C. R. B.
