temperaments. It has been supposed by some that the cerebellum is the
seat of sexual instinct. The fact appears that an ample development of
the posterior base of the cerebrum and the cerebellum indicates
nutritive activity, which is certainly a condition most favorable to the
display of amativeness. In a double sense, then, this temperament is a
vital one; both by nutritive repletion, and by reproduction. It is the
blood-manufacturing, tissue-generating, and body-constructing
temperament, causing growth to exceed waste, and promptly repairing the
wear which follows continual labor.

While the sleazy structures of the lymphatic temperament are favorable
to the functions of transudation, exhalation, and mutual diffusion of
liquids, the sanguine, as its name indicates, is adapted to promote the
circulation of the blood, to favor nutrition and reproduction. The
former temperament does not move the world by its energies, or impress
it vividly with its wisdom, and the latter is more enthusiastic,
enjoyable, and quickening. Each temperament, however, possesses salient
qualities and advantages.

THE LIFE LINE.

Dr. W.B. Powell, in his work on "The Human Temperaments," announces the
discovery of a measurement which indicates the tenacity of life, and the
vital possessions of the individual. He has observed that some persons
of very feeble appearance possess remarkable powers of resistance to
disease, and continue to live until the machinery of life literally
wears out. Others, apparently stronger and more robust, die before the
usual term of life is half completed. He also noticed that some families
were remarkable for their longevity, while others reached only a certain
age, less than the average term of life, and then died. He remarked also
that some patients sank under attacks of disease, when, to all
appearances, they should recover, and that others recovered, when,
according to all reasonable calculations, they ought to die. He,
therefore, not only believed that the duration of human life was more
definitely fixed by the organization than is supposed, but he set
himself to work to discover the line of life, and the measure of its
duration. He made a distinction between vital vigor, and vital tenacity.
_Vital vigor_ he believed to be equivalent to the condition of vitality,
which is indicated by the breadth of the brain found in the sanguine
temperament; and _vital tenacity_ to be measured by the _depth_ of the
base
