On the question of the innervation of the movements of the pupil

In the next group of experiments, we studied the question of reflex dilation of the pupil with irritation of sensory nerves after overloading n. optici inside the skull, wishing to supplement the observation of the operated animals presented in the first section of the work. Of this group of experiments, only in some of which photographic registration was applied, in experiments relating to the early period of our work, we used the usual measuring method. As in other groups, we do not present all the experiments here, since many gave completely similar results, but we will present only the most valuable, typical ones.
