It is almost cylindrical in form but is slightly flattened anteriorly and posteriorly. It extends from the foramen magnum, where it is continuous with the medulla oblongata of the brain, to the lower border of the body of the first or the upper border of the body of the second lumbar vertebra.

The advance of development progressively limits the possible operations of the inferior set of factors, so that, by both positive and negative limitations, reversal of the initial sex-index becomes increasingly more difficult. It has long been known that the degree of development of the sexcharacters that arise after birth is dependent in mammals upon internal secretions of the sex-glands (sex-hormones) circulating in the...

Page 387 - The charm of neurology, above all other branches of practical medicine, lies in the way it forces us into daily contact with principles. A knowledge of the structure and functions of the nervous system is necessary to explain the simplest phenomena of disease, and this can be only attained by thinking scientifically.
