are better adapted to cold climates, because magnetism dominates over electricity, consequently they produce more animal heat, and are better able to endure the rigors of a cold climate. The same general conditions are found to exist in birds and animals inhabiting northern latitudes.
ANATOMICAL TEMPERAMENTS.
The Temperaments are also classed anatomically as:
MOTIVE, where the bones are large and strong and the muscular development is stronger than the nutritive or mental system. Persons of this temperament are active, energetic, and best adapted to out-door pursuits and vigorous employment.
VITAL, in which the nutritive or vital system is most active, large lungs, stomach and blood vessels, and corpulent and plump figure. Persons possessing temperament are inclined to sedentary occupations, and if the brain is large and of good quality, are able to do an immense amount of mental labor without breaking down. They should take systematic exercise and avoid fats and stimulating foods and drinks to obtain the best results.
MENTAL, in which the brain and nerves are most active. The body is not adapted to hard muscular labor, and there is not enough vitality of nutritive power to nourish the brain in the heavy demands made upon it. Such persons incline to mental effort and literary work, and for a time display great brilliancy, but sooner or later collapse, unless this condition is corrected, by regular hours, plenty of sleep, the absence of stimulants and the cultivation of muscular and vital force. This temperament is distinguished by a relatively large head and small body, pyriform face, high, wide forehead, and usually sharp features.
CHEMICAL TEMPERAMENTS.
There are three principal fluids which circulate through the body, viz., arterial blood, venous blood, and lymph. As the blood passes out from the heart through the arteries it is strongly charged with magnetism and is very strongly acid in quality. As it returns to the heart through the veins it has expended its
