thrill of conjunction or collision between the divided nuclei, and at once the second birth takes place. The two nuclei now split horizontally. There is a horizontal division across the whole egg-cell, and the nuclei are now four, two above, and two below. But those below retain their original nature, those above are new in nature. And those above correspond again to those below.

In the developed child, the great horizontal division of the egg-cell, resulting in four nuclei, this remains the same. The horizontal division-wall is the diaphragm. The two upper nuclei are the two great nerve-centers, the cardiac plexus and the thoracic ganglion. We have again a sympathetic center primal in activity and knowledge, and a corresponding voluntary center. In the center of the breast, the cardiac plexus acts as the great sympathetic
