The ' tonus is little if at all increased by closure of weaker currents (a, &), which essentially inhibit it. Closure of a strong current on the other hand = c. previous data re tetanisation of the nerve—distinguish the adductor muscle sharply from the abductor. In the first place, it is evident that in preparations of the former muscle weak currents and medium currents have a predominantly inhibitory action, while with stronger currents the effects of excitation preponderate, or alone appear (Fig. 195, a, It}. This is expressed, on the one hand, in the fact that the augmentation of tonus that invariably corresponds with the moment of closure, shortening of the muscle, increases with increasing intensity of current to a certain upper limit, which (from the mechanical conditions of the experiment) is
