I. _Quality._ In the first place, let us consider that which the phrenologists call "Quality," by which they express the various degrees of fineness or coarseness in a man's mental make-up which is usually indicated by his appearance and physical characteristics. This "quality" in a man is akin to what we call "class," "breeding," or "blood" in the higher animals. It is difficult to explain, but is universally recognized. At one extreme of "quality" we find those individuals who are fine-grained, refined, high-strung, intense, and inclined to be susceptible to emotional or sentimental influence, poetry, music, etc., and are apt to be more or less impractical and out of harmony with the material world of men and affairs. At the other extreme we find those individuals who are coarse-grained, of coarse and unrefined tastes, animal, gross, unrefined, and generally "swinish." Between these two extremes we find many degrees in the scale. The outward physical signs of the person, such as the coarseness or fineness of his skin, hair, nails, ears and facial features, as well as his general form and characteristics, will usually give the careful observer the key to the degree of a man's "quality." It will be well for the Salesman to acquaint himself with these characteristics, for they throw much light on the general character of people. Next in order come what are called the Temperaments, by which term phrenologists designate the general classes into which individuals fit. As a rule, however, an individual manifests the elements of several of the temperaments--that is, they blend in him. The best phrenological authorities classify the temperaments as follows: (1) The Vital; (2) The Motive; (3) The Mental; the characteristics of which are described as follows:
