This is of two classes: first, a simple opening in the vertebral canal, and, second, a large cleft sufficient to allow the egress of spinal membranes and substance. Achard speaks of partial duplication of the central canal of the spinal cord. De Cecco reports a singular case of duplication of the lumbar segment of the spinal cord. Wagner speaks of duplication of a portion of the spinal cord.
Thomas F. Ryan became secretary of the new corporation, and William C. Whitney an active participant in its affairs. This Broadway franchise formed the vertebral column of the New York transit system; with it as a basis, the operators formed the Metropolitan Street Railway Company in 1893, commonly known as the "Metropolitan."
Man is the only animal in the world who can straighten his body and stand perfectly erect. Even the anthropoid apes when standing on their feet assume a somewhat oblique position. The vertebral column in animal life was first developed on the horizontal plane, and so, naturally, when man was evolved and adopted the erect position, certain modifications of the spine were necessary.
He was dressed very tastefully, too, as if he knew he was a good-looking fellow. He had on a new blue woolen Havre frock, with a new silk handkerchief round his neck, passed through one of the vertebral bones of a shark, highly polished and carved.
We were content to visit him now and then, to arouse him, and then leave him to disincarnate his vertebral outward phase into chlorophyll or lifeless stone. To muse upon his courtship or emotions was impossible. His life had a feeling of sphinx-like duration Gawain as a tadpole was unthinkable. He seemed ageless, unreal, wonderfully beautiful, and wholly inexplicable.
In the lunar or weekly recurrent periods of some of our functions we apparently still retain traces of our primordial birthplace, a shore washed by the tides. At about this same early period the true kidneys were replaced by the corpora wolffiana. The heart existed as a simple pulsating vessel; and the chorda dorsalis took the place of a vertebral column.
These possess neither brain nor spinal cord; their nerve-centres, instead of being concentrated in a cranium and vertebral canal, are entirely disseminated through the cavities of the trunk, as are the visceral plexuses in vertebrated animals.
The disorder mainly affects the ossifying junctions of the long bones of the extremities, the vertebral border of the scapula, and the cristal border of the ilium.
The gain by the present method is incomparable. Intersecting at Albany, New York, with the line from Vanceborough, Maine, to San Francisco, just described, or perhaps what may be called the vertebral column of the system, is the New York and Chicago railway post-office line, known also as the "Fast Mail" or the "White Mail," as the mail-cars on this line were originally painted white.
Unnatural curves of the spine throw different parts of the body out of their natural positions, diminish the thoracic and abdominal cavities, and, according to the belief of certain physicians, compress the nerves that pass from the cord to other parts of the body. Slightly misplaced vertebræ in the neck, by compressing the vertebral arteries, may also interfere with the supply of blood
