A systematic study of the resistance of heliozoan axopodia to pressure‐induced disintegrational changes has shown that progressively higher concentrations of D 2 O in the environing medium produce a progressively greater stability, not only as to the needle‐like form of the whole axopodia, but also as to their microtubular components. Also it was found that a higher temperature (25°C) yielded significantly higher stability values with identical degrees of deuteration, as compared with experiments performed at a lower temperature (20°C).
