Excerpt from The Homeopathic Journal of Obstetrics, Gynecology and Pedology, 1894, Vol. 16 The 'foregoing remarks are intended to be preliminary, and by them we can understand the law of development that has received such brilliant illustration through Von Gudden's experiments. Von Gudden took young animals at the time of birth and extirpated some peripheral organ or part. The animals were allowed to grow to the adult period and then, being killed, their nervous systems were examined, by comparing the two sides. In this way a great deal was learned of the anatomical position of certain fiber tracts. But the experiments taught more than this. They taught a great physiological law, that development of a tract depends upon its being called into activity. With these conclusions before us, we can readily under stand why injury to a part of the nervous system in the infant acts at times so differently from a precisely similar injury in the adult. We may divide disease of the nervous system (including the effects of mechanical injury) in the infant into three classes 1. Those beginning during intra-uterine life. 2. Those begun during the process of birth. 3. Those dating from a later period. In the first class are included maldevelopment, which results in the production of monstrosities with absence of brain or of skull, or with hernia of brain membranes, includ ing at times some of the brain mass. The mode of causation of such faulty development is at present beyond our ken. The cases themselves are readily recognizable and rarely survive.
