In TTX and 20 mr+t barium, sustained inward current were evoked by voltage steps positive to -30 mV. The activation energy for growth of small nuclei is shown to be higher than that for growth of nuclei of visible size; this concept requires the introduction of a slow growth correction, and the pressure of nitrogen expressed as a function of time of heating t is then given by a relation of the formula p = const. Many other binary nitrogen hydrides are known, but the most important are hydrazine (N 2 H 4 ) and hydrogen azide (HN 3 ). BARIUM AZIDE, WETTED WITH NOT LESS THAN 50% WATER is a suspension or slurry of of an unstable solid in sufficient water to allow safe shipping and handling. Sodium azide is more harmful to the heart and the brain than to other organs, because the heart and the brain use a lot of oxygen. 17.
