The right humerus was fractured at the external condyle; there was a fracture of the coronoid process of the ulna, and a backward dislocation at the elbow. The annular ligament was ruptured, and the radius was separated from the ulna. On the left side there was a fracture of the anatomic neck of the humerus, and a dislocation downward.
Thus the direction of the hair on the lower part of our arm reminds us to-day of that useful custom of our anthropoid ancestors. The nervous system in man and all the other Vertebrates is, when fully formed, an extremely complex apparatus, that we may compare, in anatomic structure and physiological function, with an extensive telegraphic system.
If we had this unknown pithecoid stem-form before us, we should certainly put it in the order of the true apes in the primate system; but within this order we cannot, for the anatomic and ontogenetic reasons we have seen, separate man from the group of the anthropoid apes.
No one can doubt the momentous bearing of these embryonic phenomena. Human embryo, three months old, natural size, from the dorsal side: brain and spinal cord exposed. Central marrow of a human embryo, four months old, natural size, from the back. In order to understand them fully we must first say a word or two of the general form and the anatomic composition of the mature human central marrow.
An analogous case was that of "A-Ke," a Chinaman, who was exhibited in London early in the century, and of whom and his parasite anatomic models are seen in our museums. CLASS IX. Of "Lusus naturae" none is more curious than that of duplication of the lower extremities. Pare says that on January 9, 1529, there was living in Germany a male infant having four legs and four arms.
The anatomic changes in the glands and substance of the uterus also favor the irritation, and the development of new growths, which may be malignant or benign as cancers, fibroid growths, and so forth. Hemorrhage at the Menopause a Significant Symptom of Cancer.
And since these endocrines control not only physique and physiognomy, anatomic and functional minutiae, but also mind and behaviour, we are justified in putting down the white man's predominance on the planet to a greater all-around concentration in his blood of the omnipotent hormones. While the Negro is relatively subadrenal, the Mongol is relatively subthyroid.
Sherrington, that masterly physiologist, in his volume entitled "The Integrative Action of the Nervous System," shows clearly how the central nervous system was built up in the process of evolution. Sherrington has made free use of Darwin's doctrine in explaining physiologic functions, just as anatomists have extensively utilized it in the explanation of the genesis of anatomic forms.
In every case, first three, then five, vesicles develop from this bulb, and the permanent brain with all its complex anatomic structures, of so great a variety in the various classes of Vertebrates, is formed from the five primitive vesicles.
When one sees the fragile woman aggressive, the masculinoid woman submissive, one may infer an education of experience that has brought the usually recessive glands into the foreground, and by their hyperactivity imposed a bisexuality of function upon a unisexual anatomic structure. A man apparently as formidable as a tyrannosaurus, may be ruled by his wife for the same reason.
