Lymph is the characteristic of the lymphatic temperament, and its specific gravity, temperature, and standard of vitality are all lower than that of red blood. In the sanguine temperament all the vital functions are more active, the blood itself has a deeper hue, its corpuscles carry more oxygen, the complexion is quite florid, and the arterial currents impart to every faculty a more hopeful vigor. The blood-vessels are the most active absorbents, eagerly appropriating nutritive materials for the general circulation, while the respiration adds to it oxygen, that agent which makes vital manifestation possible. This temperament exhibits greater sensibility, the conceptions are quicker, the imagination more vivid, the appetite stronger, the passions more violent, and there is found every display of animal life and enjoyment. A full development of the basilar faculties, indicated by an unusual breadth and depth of the base of the brain, accompanies this temperament. Its cerebral area includes the posterior and inferior portions of the cerebrum, the entire cerebellum, and that part of the medulla which connects with the spinal cord, all of which sustain intimate relations to vital conditions. Accordingly, such a development indicates good digestion, active nutrition, vigorous secretion, large heart and lungs, powerful muscles, and surplus vitality. The violent faculties, such as Combativeness, Destructiveness, and Hatred, are natural adjuncts, and their excess tends to sensuality and crime. They are not only secretive, appropriative, selfish, and self-defensive, but when redundant are aggressive and tend to destructiveness, the gratification of animal indulgence, intemperance, and debauchery. The correspondence between the cerebral conformation and the physical development is very obvious. Lower orders of animals possess these faculties, and their spontaneous exhibition is called instinct. They possess the acquisitive, destructive, and propagative propensities, which lead them to provide for their wants and secure to themselves a posterity. The exercise of their bodies causes a continual waste which demands incessant reparation, and they are governed measurably by these animal impulses.
